METHOD FOR THE PRODUCTION OF A STRUCTURAL PART COMPRISING A RIGID MATERIAL AND A PLASTIC MATERIAL, AND STRUCTURAL COMPOSITE PART THUS OBTAINED

摘要

The invention relates to a method for the production of a structural part comprising a rigid material and a plastic material and to the structural composite part thus obtained. The inventive method consists in: injecting a melted plastic material into a mould containing a plate part (10) with at least one hole (13) which is disposed between first and second cavities (21, 22); subsequently, removing the plate part (10) from the mould, said part comprising (i) at least one plastic stiffening rib (30) which is adjacent to one of the faces (11) thereof and (ii) at least one protrusion which is solidly connected to the rib (30) and which projects out from the other side (12) through the above-mentioned hole (13); and, finally, deforming the protrusion through the application of heat and pressure in order to form a fixing head (32) with a grip configuration (33). The structural composite part comprises the plate part (10) and the reinforcing rib (30) which is solidly connected thereto using the aforementioned fixing head (32).
