Background technology
The application of fibrous composite constantly occurs nearly ten years, if particularly they can think the cost-efficient alternative of metal material, has and designs freely and special formulation possibility.Especially material C FRP (carbon fibre reinforced plastic) has extremely high light structure potentiality, wherein it is characterized in that its high strength and its very high structural rigidity.The latter is the criterion of particular importance in automobile engineering.
Therefore current development activities for the treatment of the production facility of fibrous composite extends until one-stop production system from pure mechanical development.
Pure machinery comprises conventional preform production unit, squeeze unit and injecting unit and post-processing unit alternatively, and the corresponding automation that one-stop production system comprises preform process, instrument cleans, parts remove etc.
Preform can key technology in the production process of fiber composite component that strengthens of the automated production fibrae circulares that realizes beyond doubt there is the effective large-scale production can reproducing stable part quality.But, equally at so-called mixing part (namely, the part of compression molding, it is mainly the semi-finished product with carbon fiber compression,) when, in order to strengthen critical load region extraly, all production units are necessary can be integrated about facility, and control whether realize enough survival rates.
In order to produce the part that fibrae circulares strengthens, fabric fibre semi-finished product (such as silvalin, its with binding agent (hotmelt) wetting and/or be impregnated with partially or completely matrix and/or such as fibrous woven, braiding or the smooth formation (so-called prepreg) of diablement fort or mat be main at present use.The matrix of fibre reinforced plastics has embedding high capacity fiber (support function) and fills up the object of its intermediate space (blocking function) completely.
Substantially, can be used as binding agent and/or matrix material from thermoplastic or thermosetting plastics and the material of the group of elastification composition (such as elastomeric material) that may add, they are different in intensity, maximum elongation, serviceability temperature, processing speed and chemical resistance.Thermosetting moulding compound can be plastified by temperature action, can be molded at this moment, then irreversibly solidifies under pressure and temperature.Compared to thermoplastic, elastomeric material and thermosetting plastics (also referred to as thermosets) after treatment (that is, in the ready-to-use condition) be made up of neither fusible also insoluble macromolecule of more or less strong cross-linking.
In cutting process, form blank from these semi-finished product of the web-like or tablet that can be used as canonical form, this cutting process generally makes the parts reshaped be in line over its entire surface.Depend on part geometry, can produce during the cutting of blank and can not process in a large number and the remarkable cutting waste material worsening the efficiency of this process.
In order to improve resource efficiency, at significantly more less waste material or the part that fibrae circulares strengthens when not having waste material, can be produced via the method being called fleece-laying or lay also referred to as band.Especially the use of thermoplastic cyclic's fabric strip has proved very attracting process variant.In this case, especially techonosphere casting die and lay the fibrous composite being generally provided as band and represent a specific difficult problem.
" band " under the utility model implication preferably means to be adapted to pass through the netted pre impregnated material of any type of band laying apparatus deposition, such as, 30 and 150mm wide between pre-preg strip material.In such cases, " pre impregnated material " specifically means the fabric of silvalin (rove), fiber linen-cotton and/or fibrous woven, and it soaks and/or be impregnated with partially or completely particularly pre-soaked matrix, is such as thermosetting plastics matrix or thermoplastic matrix with binding agent.
" fiber " particularly carbon fiber, but glass fibre or other fiber (particularly staple fibre) also can use in an identical manner.
Band can be arranged on carrier material (being specially carrier film or paper-carrier), and make in the string of deposits with in the process of techonosphere casting die, be with and throw off from carrier material, wherein carrier material removes by being with the suitable element of laying apparatus, such as rolling.But, also can use the band no longer needing carrier material.
In order to process band, it is known for they being extracted out from wreath or roll, they being cut into certain length and they being deposited on laying platform or being positioned at the laying band structure laid platform.Due to the deposition of tape, be positioned at beneath belt with being connected in dots via multiple ultrasonic horn.In this case, the binding site separated between two belts being only laid on above another at keeps together by spot welding all the time.The fabric strip structure of the complexity deposited in this way is therefore only to be interconnected at each point place.Bonding force is enough, with from taping structure on platform, and uses and such as inhales clipping system and carry out moving belt structure.But, due to unstable bonding force, such as heating tape structure being reshaped as parts are impossible equably in infrared (IR) heating panel.In this case, each band is separated from each other, and can not reshape in reliable process.
Known prior art in the process of the band structure of the laying fixed at each point place is consolidation in press.If band comprises thermoplastic matrix, first total must be heated to fusing or flowing temperature so in this case, and again cools down under flat compressed pressure subsequently.Energy expenditure is for this purpose very high, and therefore makes whole method not have cost benefit.In addition, due to the fusing completely of total, less desirable flow operation may occur, during this period outside extrded material in pressure planes.Then this cause the violent displacement of fiber-wall-element model, and this can cause lower strength of parts.
Therefore, it is possible to the automatics of the string of deposits is also with laying method for the treatment of band or execution at present continually in a structured manner.Particularly, so-called band laying apparatus is known, and in such cases, so-called band laying apparatus is also interpreted as and comprises such as so-called fiber apparatus for placing.
In autodeposition process, band to be deposited (depends on the type of used band laying apparatus by paving head, such as via sliding shoes or contact roller) use smaller, only local and very the pressure of short-term be pressed on the band structure that deposited, with make band to be deposited and the band structure to have deposited continuously (that is, only step by step or sequentially) gluing a little or weld.But, for this purpose, in band to be deposited or the band structure that deposited, need suitable viscosity or the Weldability of binding agent and/or matrix system.
In the processing procedure of band with thermosetting adhesive and/or matrix system, viscosity can be increased by the heating of appropriateness.Therefore, such as, guide thermal current to be known through band to be deposited, this can cause the heating of band to be deposited by thermal convection current.But, show, by the above-mentioned heating of thermal current, only there is slight heat-transfer character, and cause the low firing rate of band to be deposited, therefore make the deposition velocity expected not to be achieved.In addition, the use of hot-air is unsuitable for the nearly surface fusion of the band with thermoplastic binding agent and/or matrix system.
This technology is such as improved in WO2009/130087A1, preferably also can deposited thermoplastic be with thus.In this case, exciting unit is attached to paving head, exciting unit use ultrasonic, induction and/or infrared ray, and when band to be deposited sedimentation time not long ago from such as volume or roll extract out time, exciting unit heats this band partly on the thickness of band to be deposited, and this band heated partly is pressed in continuously on the band structure deposited via flexible lay down roller, and therefore makes them continuously combine.
But because it is only with the embodiment that the mode of local finite works, this process of deployment is also restricted in laying speed, and is therefore not suitable for the large-area applications of energy large-scale production especially.
In addition, during the consolidation of large-area applications, less desirable flow operation and fiber change had both occurred in band to be deposited, also occurred in uppermost belt or the band structure deposited as the structure of the band heated due to process throughout its thickness.This can cause the internal elasticity in whole band structure, and this may cause the remarkable deterioration of parts warpage and component physical character.
Finally, with reference to EP1315613B1, the document discloses the method and apparatus for the production of senior composite construction, it comprises following steps:
-use assembly line to apply and in conjunction with first group of fiber, wherein matrix material is attached to first group of fiber with the first angle;
-use assembly line to apply and in conjunction with second group of fiber, wherein matrix material is attached to second group of fiber with the second angle;
-wherein the first angle be different from the second angle, and
-it intermittently applies first group of fiber, and
-it intermittently applies second group of fiber, can provide otch in composite material parts.
