The method is especially used for performing additional hardening on a fiber-reinforced vehicle body structural member of a motor vehicle, and comprises the following steps: providing a fiber-reinforced structural member defining at least one cavity; importing a foam material into the at least one cavity; at least partially filling the at least one cavity with the foam material; and hardening the foam material. In addition, a structural member which is manufactured correspondingly is also introduced.
Description
Technical field
The present invention relates to a kind of method for carrying out additional hardening to the fiber reinforcement vehicle body structure component of fiber reinforcing texture component, particularly Motor Vehicle.
Background technique
Fiber reinforcing texture component is more and more applied in a motor vehicle, because possess very high rigidity lightweight compared with the respective members made of they and metallic material simultaneously.
It is known that be incorporated in the cavity of fiber reinforcing texture component by a foam core, this foam core is used as supporting-core and additionally supporting structure component, further increases the intensity rigidity in other words of whole component in this way.
Usually, fiber reinforcing texture component is made with shell form construction form, and wherein a prior prefabricated and foam core be arranged between housing is surrounded by two housings.Precondition is: foam core must accurately carry out cutting blanking according to the cavity defined by two housings and be placed into and locate in an independent treating process.In addition, foam core extends on the broad area of construction element under normal conditions, to play a supporting role in plurality of positions.Thereby produce the shortcoming in the construction weight of materials consumption and generation.
Alternatively, such as known by DE 10 2,011 083 162 A1: foam core to be arranged between two fiber composite layer and to be just integrated in component when utilizing shaping die to extrude.
Summary of the invention
Therefore the object of the invention is, a kind of simple as far as possible method for the manufacture of fiber reinforcing texture component be provided, the method raw material drop into the least possible and weight light as far as possible while can strengthening structure component better.
For this reason, the present invention proposes a kind of method for carrying out additional hardening to the fiber reinforcement vehicle body structure component of fiber reinforcing texture component, particularly Motor Vehicle, comprises the following steps:
-the fiber reinforcing texture component defining at least one cavity is provided, and then
-foamed material is imported at least one cavity described,
-at least one cavity described is loaded foamed material at least in part, and
-foamed material is hardened.
So foamed material is packed in one or more cavity of the construction element made.Cavity is partially or even wholly loaded foamed material.Preferably, cavity is at least full of with foamed material completely after described sclerosis.
By follow-up for foamed material importing after really making fiber reinforcing texture component, can realize manufacturing and the later foamed material determination strength characteristics again by inserting the unified of construction element.Like this, the component with varying strength characteristic can be produced by the application of different foamed materials in a particularly simple way.It is particularly favourable that this point such as derives parts for the vehicle with varying strength requirement, because construction element first can be manufactured as same parts, then just different according to the different choice of foamed material.
As the material for fiber reinforcing texture component, particularly can use fiber reinforced plastic, these plastics utilize glass fibre, aramide-fibre and/or fibre reinforced.Self-evident, but other can be used equally to be applicable to the fiber of reinforced plastic.
Preferably, the foam material adheres be imported in cavity is limiting on the wall of this cavity at least in part, thus allow the power transmission between foamed material and construction element, thus, the intensity of construction element is particularly by being improved the absorption of shearing and transmission.
Such as, described foamed material can comprise the plastic foam that can expand, particularly polyurethane foam or epoxy foams.Polyurethane foam or epoxy foams can be made up of two-component system or multicomponent system.The plastic foam that use can be expanded presents following advantage: foamed material in the filling process or before the hardening, its volume increases, and is suitable in this way being full of at least one cavity described as far as possible completely.This point just can be paid attention to when filled and process material, thus so many foamed material only imports in cavity by the expansiveness according to foamed material, makes this foamed material just be full of cavity completely in swelling state.
According to a mode of execution, such as, realize described foamed material by gap mouth, the particularly hole limited in the wall of at least one cavity described and import.
Preferably, at least one cavity described defines the space substantially closed.This means: corresponding cavity all each relative to surrounding environment otherwise relative to other cavitys be completely (for import foamed material gap mouth except) close, thus the foamed material be imported into can not spill.Optionally, this space can only so be closed to degree for same object: although there is opening, but the size of these openings be defined as substantially preventing foamed material from flowing out.Such as can realize this point in the following way, namely the size dimension of opening is determined enough little and hardening characteristics of harmonizing in this wise, and the foamed material making foamed material also thus opening is directed to other follow-up inflows when passing opening with regard to so promptly sclerosis is closed.Under any circumstance, a kind of volume determined of foamed material is formed in the cavities.
According to another mode of execution, fiber reinforcing texture component is made up of at least two interconnective shell elements, particularly two and half shell elements.These shell elements are interconnected in this wise, make between two shell elements, define at least one cavity described.
Optionally, fiber reinforcing texture component can comprise hollow profile, the hollow profile particularly woven.Method for the production of hollow braiding section bar is known, thus can omit the detailed description to manufacturing.
According to another mode of execution, fiber reinforcing texture component comprises multiple cavity, and wherein every two cavitys adjoined are separated from one another by least one next door.As next door, also can be understood as the stiffening rib of construction element.
This point provides following possibility: can at only one or implement import and load the step of foamed material, to load corresponding cavity at least in part in multiple cavity.Each cavity filled and process material selected of construction element can be given in such a way, thus construction element is reinforced on the position determined.Other cavitys then can keep non-filling state.
Each cavity be filled also can be spaced setting of turning up the soil.Remaining construction element or other cavitys region in then can save foamed material, the construction weight thereby reducing materials demand amount and produce, because need not arrange continuous print foam core in the cavity be not filled being filled between cavity of structural element.
In addition it is also possible that for the object of Weight-optimised design, can consider to adopt different foamed materials in each respective cavities of structural element.To this, that is such as can distinguish to some extent in density, intensity and/or weight, adapt to desired load partly to make construction element.In other words there is such possibility: in the first cavity (in the region of high capacity) but use high strength may be heavier than in the second cavity (in the region of low load) foamed material, less and the foamed material that is simultaneously lighter in weight of intensity can be set in the second cavity, keep very little to make the overall weight of the construction element of the Weight-optimised design had depending on claimed range.
Such as, load with foamed material described at least one cavity can be arranged on the jointing of construction element or power import in the region of section.Whereby, the section of especially these special carryings in using after construction element can be able to local strengthening targetedly.This embodiment has further advantage for following situation: multiple region to be fortified is spaced from each other setting, because unified foam core can be abandoned thus, this foam core two regions be reinforced and be located at the low load between them region on extend.
In addition, the present invention also provides a kind of fiber reinforcement vehicle body structure component of the fiber reinforcing texture component, particularly Motor Vehicle made according to the method described above.
Such as, described vehicle body structure component can be vehicle upright, Kan Liang, side direction roof frame, the crossbeam of sidewall or base assemblies or front truck or longeron.
