Abstract
A process for the bonding of a fiber-reinforced material to an injection-molding material and an article produced by the process. The process improves the bond between a fiber-reinforced starting material and a material applied by injection. A further plastics material is inserted under pressure into a fiber-reinforced plastics material. This results in interlock bonding between the further plastics material and the fibers of the fiber-reinforced plastics material. This type of bonding is substantially more stable than known bonding.
Claims8
A process for bonding a fiber-reinforced plastics material to a further plastics material, said process comprising:
- (a) introducing the fiber-reinforced plastics material into an injection mold, wherein the injection mold has, behind the fiber-reinforced plastics material introduced, at least one depression, wherein the fiber-reinforced plastics material has first and second opposing sides differing in distance from the at least one depression, and wherein the first of said opposing sides is a farther distance from said at least one depression than said second of said opposing sides, and
- (b) bonding the fiber-reinforced plastics material to the further plastics material by inserting the further plastics material under pressure into the fiber-reinforced plastics material from said first side, and continuing between fibers of said fiber-reinforced plastics material so that the fiber-reinforced plastics material is thereby displaced into the at least one depression, and the further plastics material is eventually pressed outward of the fiber-reinforced plastics material at said second side.
