Description

The invention relates to a method for producing a hybrid component. A hybrid component or a hybrid component is a component with at least two areas, the two areas being produced at least in sections from different manufacturing processes or based on different technologies. For example, up to a defined production step, a first area can have been produced separately from a second area from different production processes.

Corresponding methods for producing a hybrid component are basically known from the prior art. Here, for example, a component area of a later component produced from a machining process can be connected to a component area originating from an additive manufacturing process. The two component areas connected to one another are therefore the finished component.

The invention is based on the object of specifying a method which increases the quality and performance of a hybrid component, in particular with regard to a simple, fast and inexpensive measure.

The object is achieved by a method for producing a hybrid component according to claim 1. The dependent claims relate to possible embodiments of the method.

The invention relates to a method for producing a hybrid component or a hybrid component, having the following method steps: (a) providing a base body produced in an additive manufacturing process, (b) providing at least one supplementary body, (c) connecting the supplementary body to the base body in or on a contact surface of the base body to form the hybrid component. The method is characterized in that the base body has a lower degree of hardening and / or solidification during the connection, in particular when the supplementary body is brought into contact with the base body, at least in regions on at least one first section, which at least in sections comprises the contact surface of the base body than on at least one further section of the base body.

The sequence of process steps (a) and (b) can be selected as desired. The base body can also have been at least partially completed in an additive manufacturing process, for example prior to connecting the supplementary body, and in a further additive production process carried out on or on the contact surface of the base body after connecting the supplementary body by applying a further component area or applying a further building material in its, in particular in its essential, main design form can be completed or expanded.

Before, during and / or after it is connected to the base body, the supplementary body can, for example, have, at least in sections, in particular completely, a dimensionally stable or non-dimensionally stable property. The supplementary body can for example consist of a non-solidified and / or a non-hardened material, at least in sections. A fiber-matrix semifinished product, for example a fiber-matrix semi-finished product, can be used as a supplementary body, at least in sections, in particular completely. B. a prepreg, a BMC (Bulk Molding Compound) and / or an SMC (Sheet Molding Compound). The unconsolidated portion of the fiber-matrix material, in particular the matrix, can be consolidated together with the first section of the base body. A prepreg is a semi-finished textile fiber matrix pre-impregnated with reactive resins that cures under temperature and / or pressure. It can be provided that fibers impregnated with an at least partially unconsolidated matrix are applied to a finished or partially finished component produced in an additive manufacturing process and then cured.

It is possible that the incompletely solidified first section of the base body and / or an unconsolidated or uncured area of the supplementary body is present in a pasty or gel-like or solid form. In the case of an unconsolidated first section of the base body and / or the unconsolidated area of the supplementary body comprising a plastic, this section or area can be in a partially crosslinked state.

The base body has a contact surface in or on which a supplementary body is attached at least in sections or in or on which a supplementary body contacts the base body. In this case, there is an at least partial, preferably predominant, particularly preferably complete, connection of the supplementary body to the base body. The contact surface was formed in the additive manufacturing method, the process parameters of the additive manufacturing device for manufacturing the base body, in particular for manufacturing the contact surface, being set in such a way that at least in some areas on at least one first section of the base body, which at least in sections comprises the contact surface of the base body , a lower curing and / or Degree of solidification is present than at least one further section of the base body.

For example, the first section of the base body, which at least partially encompasses the contact surface of the base body, can be deliberately not completely or not completely solidified and / or hardened in the course of the additive manufacturing process. This incompletely hardened and / or incompletely hardened first section of the base body can thus be post-hardened and / or post-hardened in a further process step that occurs after or with the application of the supplementary body. In this way, a more intimate consolidation and / or more solid connection and / or more rigid connection of the supplementary body to the base body can be achieved, for example by the fact that a chemical bond is formed between the supplementary body and the base body.

In other words, it can be provided that a first section after its manufacture in the additive manufacturing process has a first degree of hardening and / or solidification and at least one further section after its manufacture in the additive manufacturing process a second degree of hardening and / or hardening from the first has different, in particular lower, degree of hardening and / or solidification. This different degree of hardening and / or solidification can thus produce a first section of the base body which has positive connection properties for a connection with a supplementary body.

It is possible that a formation of the at least one first section of the base body and the at least one further section of the base body with different degrees of hardening and / or solidification through targeted area-dependent action of energy in the course of the additive manufacturing process for at least sectionally, in particular complete, production of the Base body takes place. Depending on the particular additive manufacturing method used to manufacture the base body, different process parameters of the additive manufacturing method can be changed or varied for the targeted formation of differently hardened or solidified sections. A change in process parameters of the additive manufacturing method enables the base body to harden differently depending on the area, so that in this way the first and further sections of the base body can be formed with their different degrees of hardening and / or solidification. In particular, for example due to the additive manufacturing process that builds up the base body in layers, regions of the base body remote from or inside or from the surface of the base body can also be provided with different degrees of hardening and / or solidification.

For example, after the at least partially, in particular complete, production of the base body in the course of the additive manufacturing process and / or before connecting the supplementary body to the base body, the degree of hardening and / or solidification of at least a first section of the base body and the degree of hardening and / or solidification at least one further section of the base body may differ by at least 2%, preferably by at least 7%, particularly preferably by at least 20%, most preferably by at least 30%. Such a still unconsolidated or uncured first section of the base body can provide a better connection between the base body in the course of the remaining hardening in the contact state with the supplementary body, which is in particular also at least partially, preferably completely, in a defined, not fully cured or solidified degree and supplementary bodies can be achieved. The minimum degree of hardening or solidification of the not fully hardened sections / areas of the base body and / or the supplementary body can be selected such that after a supplementary body has been arranged on or on a base body, this assembly can be locally displaced without unconsolidated material from the supplementary body and / or deformed and / or released from the base body as a result of gravity and / or as a result of acceleration. In other words, the minimum degree of hardening of the material of the supplementary body and / or of the base body is selected such that these bodies have a minimum dimensional stability for the free surfaces. In contrast, at least one enclosed area can e.g. B. an area of the base body, which is enclosed on the one hand by more solidified building material of the base body and on the other hand by a supplementary body, have such a low degree of solidification that it would flow off or out if it were not enclosed.

In the course of the additive manufacturing process, a base body can preferably be produced which has at least one further section (more solidified section) that at least partially defines a structure defining an intermediate space; a first section (less solidified section) is preferably at least partially, in particular completely, in at least one intermediate space Section) of the base body arranged or formed. The further section forming the defined structure can have a higher rigidity and / or strength at least in the state immediately after the additive manufacturing process has been completed and / or, in particular immediately, before have post-consolidation of the first section of the base body. The intermediate space can be formed, for example, by a structure of the further section that surrounds this intermediate space in a ring-like or circumferential manner. The structure of the further section that forms or defines the intermediate space can be designed, for example, in the manner of an inner skeleton or an inner supporting framework or supporting structure, at least in sections, in particular completely, within the base body. This means, for example, that the further sections are made harder and / or more rigid than the at least one first section, which is softer or not completely hardened or solidified. These first sections can e.g. B. be “kept in shape” due to the further sections and be so uncured or not solidified that a connection or a connection with the supplementary bodies is improved. A further hardening and / or solidification of the at least one section preferably takes place together with the supplementary body contacting it during a post-hardening or post-hardening step.

The base body can, for example, at least in sections, in particular completely, have a grid-like structure; the grid-like structure is preferably formed by the at least one further section of the base body. The further sections forming the lattice-like structure enable the base body to be kept in shape, for example, while the first sections are more unstable sections with a low degree of hardening and / or solidification compared to the further sections.

At least one core area of the base body can, for example, have an at least regionally irregular lattice-like structure, wherein preferably first lattice elements of a first area of the core area can be designed differently compared to second lattice elements of a second area of the core area, first lattice elements being particularly preferred compared to the second lattice elements can be designed differently in terms of thickness and / or length and / or orientation and / or shape and / or spacing.

The surface of the base body facing the supplementary body can be present, for example, as a predominantly closed surface. It can thus be achieved that a lattice structure located below the closed area is protected from the penetration of particles such as e.g. B. Dirt is protected during the manufacturing process.

It is possible for the base body to be manufactured at least in sections, in particular completely, in an additive manufacturing process using plastic, preferably synthetic resin, as a building material. A base body can thus be produced which at least in sections, preferably predominantly, particularly preferably completely, consists of plastic and / or synthetic resin or is made of such a material. The building material used in the additive manufacturing process is present as a liquid or strand-like or pasty or gel-like building material during additive manufacturing. In particular, a photopolymerizable building material can be used as the building material. For example, rigid PU (e.g. E-Rigid PU from EnvisionTec), PU methacrylate, in particular methyl methacrylate (MMA), vinyl ester and / or epoxy resin can be used as building material.

In a preferred embodiment it can be provided that a supplementary body is used which has at least fiber-reinforced plastic, glass and / or metal, the supplementary body preferably having reinforcing fibers and a plastic matrix, wherein (a) the reinforcing fibers: glass fibers, carbon fibers, ceramic fibers and / or aramid fibers, and / or (b) the plastic matrix a thermoset or thermoplastic matrix, in particular epoxy resins (EP resins), polyetheretherketone (PEEK), polyphenylene sulfide (PPS), polysulfone (PSU), polyetherimide (PEI) and / or polytetrafluoroethene ( PTFE). Here, the reinforcing fiber and / or the plastic matrix can comprise one or at least two of the components mentioned. Furthermore, it can prove to be advantageous if at least the plastic matrix material is not fully cured and / or not fully solidified before it is connected to the base body and / or immediately prior to post-curing and / or post-curing of the base body and supplementary body; of the supplementary body before and / or during its placement on or on the base body to a degree of hardening and / or solidification of a maximum of 95%, preferably of a maximum of 75%, particularly preferably of a maximum of 35%, most preferably of a maximum of 5%. Alternatively or additionally, the plastic material can have an almost unconsolidated or uncured shape, at least in sections, in particular completely, before or during its placement on or on the base body. The above-mentioned optional variant relating to epoxy resins thus relates to synthetic resins which carry an epoxy group. These are curable resins that can be converted into a thermosetting plastic with a hardener and, if necessary, other additives. Epoxy resins can be present as polyethers with two terminal epoxy groups, curing agents being used as reactants in order to form a macromolecular plastic with the resin.

A carbon fiber reinforced plastic (CFRP) can be used as a supplementary body, for example, at least in sections, in particular completely.

The plastic matrix material can at least in sections, in particular completely, for example consist of a thermosetting and / or a thermoplastic material; in particular, a thermosetting plastic matrix material which has not yet or not yet fully polymerized is used.

The fibers contained in the supplementary body can be present, for example, as a, in particular, pure, unidirectional layer. The fibers can alternatively or additionally be in the form of a woven fabric or scrim. The supplementary body can be applied to the contact surface of the base body as a so-called prepreg, for example. At least one prepreg can be present, for example, as a unidirectionally reinforced and / or flat semi-finished product, the matrix preferably consisting of an incompletely hardened or incompletely solidified thermoset material.

The at least one supplementary body can for example be materially and / or non-positively and / or positively attached to the base body, preferably the at least one supplementary body is at least partially connected to the base body by forming a chemical bond in or on the contact surface of the base body, especially fully connected. In particular, if both the first section of the base body and at least some sections of the supplementary body are brought together in a not completely hardened or not completely solidified state, the merging and / or a post-hardening or post-hardening step after contacting or solidification can be used. a reliable connection can be achieved after the supplementary body has been assembled with the base body. Here, for example, free radicals of the not completely hardened first section of the base body and free radicals of the not completely hardened area, in particular of the matrix, of the supplementary body can react and thus combine with one another at the molecular level. For example, the materials can be linked together as chains and block copolymers can be formed.

The reliability, in particular the strength, of the connection between the base body and the supplementary body can be further increased, for example, in that at least one surface area of the base body has at least one receiving area in which at least a part of the supplementary body is received. The receiving area is preferably designed as a recess. Because the supplementary body is inserted into a recess in the base body, an enlarged contact surface can be kept between the base body and the supplementary body, which has a positive effect on the reliability, in particular on the strength, of the connection. In an optional embodiment, the receiving area can be surrounded at least in sections, in particular completely, by the first section.

The base body can be manufactured using one of the following manufacturing processes: Selective Laser Sintering (SLS) and / or Multi-Jet Fusion (MJF) and / or Fused Deposition Modeling (FDM) and / or Continuous Liquid Interface Production (CLIP) and / or stereolithography (SLA). The continuous liquid interface production process can also be referred to as the digital light synthesis process.

During and / or after the supplementary body is arranged on or on the contact surface of the base body, post-curing and / or post-hardening of the base body can take place, for example, at least in sections, in particular completely. Here, the base body and / or the supplementary body, in particular jointly, can be exposed to thermal energy and / or electromagnetic radiation, preferably UV light. The base body and the supplementary body can preferably be brought into an oven and post-cured there, at least with regard to the sections / areas that are not completely cured. As a result of the post-curing and / or post-consolidation of the base body and / or the supplementary body, during and / or after an arrangement of the supplementary body on or on the contact surface of the base body, at least some sections, preferably at least predominantly, particularly preferably complete, consolidation and / or curing of the Base body and / or supplementary body take place.

The post-curing and / or post-consolidation can for example take place at least in sections, in particular completely, by means of thermal energy and / or by means of electromagnetic radiation, preferably UV light. Here, for example, thermal energy can be applied by applying thermal energy in a temperature range from 0 to 400 ° C., preferably from 5 to 300 ° C., particularly preferably from 10 to 250 ° C., most preferably from 25 to 225 ° C., with a thermal exposure period from 0 to 24 hours, preferably from 1 to 22 hours.

In the course of post-curing and / or post-consolidation of the base body, in particular of the at least one first section of the base body, it can for example be provided that the degree of hardening and / or degree of solidification of the base body, in particular the degree of hardening and / or degree of solidification of the at least one first portion of the base body, by at least 2%, preferably by at least 7%, especially is preferably increased by at least 20%, most preferably by at least 30%. In this context, the degree of hardening is to be understood as meaning, for example, a strength value and / or a stiffness value which can be increased by the corresponding percentage values. In relation to a CLIP or DLS process, the degree of curing can be understood as the formation or as the formation of a polymer network through chemical bonding (e.g. degree of chemical crosslinking). The degree of chemical bonding or the degree of chemical crosslinking results in an increase in the strength and / or rigidity values. For example, the strength of the first section of the base body and / or an unconsolidated area of the supplementary body in the course of post-curing and / or post-consolidation is increased by at least 2%, preferably by at least 7%, particularly preferably by at least 20%, most preferably by at least 30%, increased.

It can prove to be advantageous if a first section of the base body has a degree of hardening and / or a degree of hardening of a maximum of 30%, preferably a maximum of 20%, compared to an area of the supplementary body before or during the post-hardening and / or post-hardening. particularly preferably by a maximum of 7%, most preferably by a maximum of 2%. Because the two not fully hardened or not fully solidified sections / areas of the base body and the supplementary body have a similar degree of hardening and / or solidification, a good connection of these areas / sections can be achieved, since they then have a similar and / or identical behavior exhibit during post-hardening or post-hardening. This effect can be increased to a particular degree by using a similar material, in particular an identical material, at least in sections for the base body and for the supplementary body. For example, the material forming the at least one first section of the base body can be at least similar, in particular identical, to the material of the incompletely solidified and / or incompletely cured supplementary body.

In addition to the method for producing a hybrid component, the invention also relates to a component, in particular a hybrid vehicle component, produced using a method described herein.

All advantages, details, designs and / or features of the method according to the invention can be transferred or applied to the molded body according to the invention.

The invention is explained in more detail by means of exemplary embodiments in the drawings. It shows:

• 1 a schematic perspective illustration of an additively manufactured base body and a supplementary body in the disconnected state according to an exemplary embodiment;
• 2 a schematic representation of a full section according to section A of the base body 1 ;
• 3 a schematic perspective illustration of a hybrid component having a supplementary body and a base body;
• 4th a schematic representation of a method sequence for producing a hybrid component according to an embodiment.

4th shows a schematic process sequence for producing a hybrid component 1 or a hybrid component with the following process steps: The first process step 101 comprises providing a base body produced in an additive manufacturing process 2 , a second process step 102 comprises the provision of at least one supplementary body 3 . In a subsequent process step 103 the supplementary body is connected 3 with the base body 2 at a contact surface 4th of the base body 2 . The joining of the supplementary body 3 with the base body 2 can run in several stages, so that in an upstream process step 103 a physical contact with the supplementary body 3 at the contact surface 4th of the base body 2 he follows. In the course of post-curing and / or post-consolidation, in a process step provided for this purpose 104 a more extensive or increased connection of the base body 2 with the supplementary body 3 respectively.

The base body 2 is exemplary in 1 shown, whereby it can be seen from this that the base body 2 during connection, in particular during making contact (see arrows 5 , 5 ' ), of the supplementary body 3 with the base body 2 at least in some areas on at least one first section 6th , at least in sections the contact surface 4th of the base body 2 comprises, has a lower degree of hardening and / or solidification than on at least one further section 7th of the base body 2 . In the example shown is the supplementary body 3 designed as a prepreg or as a textile fiber matrix semi-finished product pre-impregnated with reactive resins. Here the first section 6th a first degree of hardening and / or solidification and at least one further section 7th have a second degree of hardening and / or hardening different from the first degree of hardening and / or solidification, the degree of hardening of the first section 6th is less than the degree of hardening of the further section 7th . In other words, there is the potential for further curing or for a chemical reaction with a corresponding action on the at least one first section 6th of the base body 2 higher than for the at least one further section 7th of the base body 2 .

A formation of the at least one first section 6th of the base body 2 and the at least one further section 7th of the base body 2 can for example take place with different degrees of hardening and / or solidification. This can preferably be achieved through a targeted, area-dependent, different action of energy in the course of the additive manufacturing process for at least partially, in particular complete, manufacture of the base body 2 respectively. In this case, at least one process parameter of the additive manufacturing device (not shown) can be changed or set accordingly, so that the base body produced by means of this additive manufacturing device 2 different sections 6th , 6 ' , 7th with different degrees of hardening and / or solidification.

After making the base body 2 can in the course of the additive manufacturing process and / or before connecting the supplementary body 3 with the base body 2 the degree of hardening and / or solidification of at least a first section 6th of the base body 2 and the degree of hardening and / or solidification of at least one further section 7th of the base body 2 be different by at least 2%, preferably by at least 7%, particularly preferably by at least 20%, most preferably by at least 30%.

The degree of hardening or the degree of solidification is shown in the figures 1 and 3 shown as shaded areas, with more cured areas shown as darker areas and less cured areas as lighter areas. The areas shown in the figures as darker areas, e.g. B. the at least one further section 7th and / or the lattice structure can, for example, form at least 80%, preferably at least 90%, particularly preferably almost completely, most preferably completely, hardened and / or solidified areas. It can be seen from this that it can be provided, for example, that at least one section, in particular in the area of the first sections 6th , 6 ' on to the contact surface 4th down, weaker cured area can be provided. That means, for example, that one of the contact area 4th distant area compared to one to the contact area 4th towards the closer region of the at least one first section 6th , 6 ' have a lower degree of cure.

In the course of the additive manufacturing process, a base body 2 be produced, the at least one at least in sections one intermediate spaces 8th defining structure forming further section 7th has, is preferred in at least one intermediate space 8th at least in sections, in particular completely, a first section 6th of the base body 2 arranged or formed. In other words, it can go through the further sections 7th formed structure (z. B. lattice structure) at least one space 8th within the base body 2 form or define, the structure having a higher degree of hardening and consequently a stiffer or stronger property than the material located in the space. This stiffer or firmer structure can be used as a support or as a “form-retaining means” for the at least one first section, which has a lower degree of hardening 6th be used.

The lattice structure of the base body 2 can, for example, at least within a core area 9 have an at least regionally irregular grid-like structure, preferably first grid elements 10 a first area of the core area 9 compared to second grid elements 11 a second area of the core area 9 can be designed differently. In general, the grid elements 10 , 11 be designed differently in comparison to one another with regard to their thickness, length, orientation, shape and / or spacing. The base body 2 can be a core area 9 and at least one edge area 14th , 14 ' exhibit. At least a marginal area 14th , 14 ' can, for example, be used as a contact surface for attaching at least one supplementary body 3 serve.

It can be optional - as in 2 shown - it can be provided that at least a first surface area 12th , e.g. B. at least partially, in particular completely, the contact surface 4th forming surface area 12th , at least 50% a first main extension surface 13th of the core area 9 terminates, preferably at least 90%, a first main extension surface 13th of the core area 9 closes off, particularly preferably completely, a first main extension surface 13th of the core area 5 concludes. In other words, at least one surface, in particular the contact area 4th , the base body 2 have a predominantly or a completely closed (ie, for example, a gas- and / or liquid-tight) shape or property.

The base body 2 can for example be produced at least in sections, in particular completely, in a plastic, preferably in a synthetic resin, using additive manufacturing processes as a building material.

A supplementary body 3 can for example have at least one fiber-reinforced plastic, glass and / or metal. The supplementary body preferably has 3 at least in sections, in particular completely, reinforcing fibers and a plastic matrix, with (a) the reinforcing fibers: glass fibers, carbon fibers, ceramic fibers and / or aramid fibers, and / or (b) the plastic matrix a thermoset or thermoplastic matrix, in particular an epoxy resin (EP resin ), Polyetheretherketone (PEEK), polyphenylene sulfide (PPS), polysulfone (PSU), polyetherimide (PEI) and / or polytetrafluoroethene (PTFE). Here, the reinforcing fiber and / or the plastic matrix can comprise one or at least two of the components mentioned. In particular, the supplementary body 3 Include carbon fiber reinforced plastic.

The at least one supplementary body 3 can, for example, cohesively and / or non-positively and / or positively on the base body 2 be attached. The at least one supplementary body is preferably 3 with the base body 2 through the formation of a chemical compound in or on the contact surface 4th of the base body 2 at least in sections, in particular completely, connected.

At least a surface area 12th of the base body 2 can for example have at least one receiving area (not shown) in which at least a part of the supplementary body 3 is received, preferably the receiving area is designed as a recess. For example, the receiving area can have a U-shaped recess in cross section into which the supplementary body 3 can be introduced at least in sections and in the introduced state in the course of post-curing finally together with the not completely cured areas of the base body 2 (e.g. with the first section 6th , 6 ' ) are cured and connected to it.

The base body 2 can be manufactured or generated, for example, by means of one of the following manufacturing processes: Selective Laser Sintering (SLS) and / or Multi-Jet Fusion (MJF) and / or Fused Deposition Modeling (FDM) and / or Continuous Liquid Interface Production (CLIP) and / or stereolithography (SLA). The Continuous Liquid Interface Production process can also be referred to as Digital Light Synthesis (DLS). In this case, at least one process parameter can be selected in the respective method so that at least a first section 6th of the base body 2 is not completely cured or for a subsequent arrangement process step for the arrangement of the supplementary body 3 on the base body 2 a certain (residual) hardenability can be retained.

During and / or after arranging the supplementary body 3 on or on the contact surface 4th of the base body 2 (see process step 103 ), for example, post-curing of the base body, at least in sections, in particular completely 2 take place, see process step 104 . In addition, during the post-curing of the base body 2 also the supplementary body 3 experience post-curing, ie that not yet fully solidified sections / areas of the base body 2 and the supplementary body 3 in the course of post-curing, in particular together, experience an increase in the degree of curing. For example, in the post-curing process, the areas / sections of the base body that were not fully cured before the start of the post-curing process are completely cured 2 and the supplementary body 3 .

The post-curing and / or post-consolidation can for example take place at least in sections, in particular completely, by means of thermal energy and / or by means of electromagnetic radiation, in particular UV light. Here, the base body 2 and / or the supplementary body 3 be acted upon with thermal energy or with UV light, so that due to the transferred thermal energy or due to the UV light there is an increase in the degree of solidification or an increase in the degree of hardening in the base body 2 and / or in the supplementary body 3 results. Here, the material of the base body 2 and / or the supplementary body 3 for example, by exposure to electromagnetic radiation, in particular UV light, carry out a photopolymerization.

In the course of post-hardening and / or post-hardening of the base body 2 , in particular of the at least one first section 6th of the base body 2 , for example, the degree of hardening and / or degree of solidification of the base body 2 , in particular the degree of hardening and / or degree of solidification of the at least one first section 6th of the base body 2 can be increased by at least 2%, preferably by at least 7%, particularly preferably by at least 20%, most preferably by at least 30%.
