While thermoplastic materials allow for a wide range of fusion bonding techniques, for example induction welding and ultrasonic welding [4], thermoset materials do not offer the possibility of fusion bonding once they are fully cured.
Experimental Materials.
Two materials and processing routes were applied to show the applicability of the modified co-curing method for both processing routes.
