Problems solved by technology

The separate method steps, namely the forming of the metal carrier and the forming of the FVK part, together with their final connection (for example with bolts (DE 10 2009 009 112 A1)) are relatively expensive to carry out and additionally require costly semi-finished products or components , especially the method requires a relatively high cost of automation

Embodiment Construction

[0023] according to figure 1 The shown method sequence 1 for producing a component 2, in a first step, a curable coating 6 with fiber-reinforced synthetic material (FVK) is applied to the metal detached from a coil 4 of steel sheet 5 on carrier 3. The metal carrier 3 may also have previously been cleaned or chemically pretreated on the side to be coated, but this will not be explained in detail. A robot 7 is provided for applying the coating 6 , which receives the blank 8 of the robot 9 . For this purpose, the robot arm 9 cuts the fabric 10 pre-impregnated with a synthetic material matrix according to the area of ​​the metal carrier 3 to be coated. The coated metal carrier 3 is then subjected to partial curing by means of a drying or curing device 11 , whereby the coating 6 forms at least one anti-adhesion surface 12 . As a result, the metal carriers 3 can also easily be laid into stacks 13 and thus, for example, temporarily stored or prepared for further transport. In par...

Abstract

The invention proposes a method for producing a semi-finished product or component (2), in which method a curable coating (6, 17) with fiber-reinforced synthetic material is applied to a metal support (3), especially a plate (4) and in a subsequent step the coated metal carrier (3) is deformed, in particular deep-drawn or bent into a semi-finished product or component (2). For an improved and cost-effective method it is proposed to coat the metal carrier (3) at most regionally and only when the coating (6, 17) of the metal carrier forms at least one anti-adhesion surface (12) during its curing. ), undergoes deformation, wherein the coated metal carrier (3) is deformed in such a way that its plastic shape change with the deformation radius (21) is substantially, preferably only, in the uncoated part of the metal carrier Layer region (15) is formed.

Description

technical field [0001] The invention relates to a method for producing semi-finished products or components, in which method a curable coating with fiber-reinforced synthetic material is applied to a metal support, especially a plate, and in a subsequent step, the The coated metal carrier is deformed, especially deep-drawn or bent into semi-finished products or components. Background technique [0002] Hybrid materials are known from the prior art (DE19956394B4), which have a plurality of metal layers placed one above the other, which are each coated with a fiber-reinforced unidirectional prepreg layer over the entire surface, the prepreg layer on the hybrid material The profile is cured after deformation. Disadvantageously, however, such methods are sensitive to premature curing of the prepreg layers before the hybrid material has acquired its final shape through its deformation. This can be seen in particular if the deformed hybrid material reduces the shape accuracy and...
