FIBER-REINFORCED THERMOPLASTIC SYNTHETIC RESIN MEMBER AND MANUFACTURE OF MELT JOINING JOINT THEREOF

摘要

In a method of manufacturing a fusion bonded joint between a fibre reinforced thermoplastic resin component having at least 30 per cent of its volume comprised by reinforcing fibres (high fibre loaded) and another fibre reinforced thermoplastic resin component having more or less than 30 per cent of its volume comprised by reinforcing fibres, additional thermoplastic resin is incorporated at the joint interface prior to joining by fusion bonding. The additional thermoplastic resin is preferably consolidated in those surfaces of the high fibre loaded component which are to be joined to other components before fusion bonding takes place. A preferred method of fusion bonding is by ultrasonic welding. A mesh comprising metal strands extending at least across the joint may be incorporated at the interface of a joint between two components to provide increased joint strength and electrical conductivity across the joint in the case of carbon fibre reinforced components.
