PROCESS FOR PRODUCING SURFACE-FINISHED LIGHTWEIGHT COMPONENTS WITH HIGH NATURAL FIBRE CONTENT AND INTEGRATED FASTENING ELEMENTS

摘要

A process is described for producing a lightweight component comprising natural fibres (FRP component), which has a visible side and a fastening side. In order to manufacture a lightweight FRP component with a high degree of design freedom, any desired type of surface, and substantially reduced cost for downstream operations, the following production steps are proposed according to the invention: a) insertion of a semifinished natural fibre product into an injection mould, b) a pressing and/or forming process, and also consolidation of the semifinished natural fibre product, to give a moulding in the injection mould, c) injection to add functional elements, in particular fastening elements, and/or reinforcing structures, onto the moulding on the fastening side of the lightweight component, into unoccupied spaces in the injection mould, the functional elements, in particular the fastening elements and/or the reinforcing structures being injected only onto a portion of the area of the fastening side, and d) applying the surface component in a prescribed region of the visible side of the moulding.
