  • Connecting fiber-reinforced material to an injection-moulded material
    Patent number: 8617442
    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.
