there is currently a great deal of interest in the use of thermoplastic polymers as matrices in fiber reinforced composites for high performance applications, such as those encountered in the aerospace industry. these materials include polyether ether ketone (peek), polyphenylene sulphide (pps), polyetherimide (pei), polyamideimide (pai), polyamides, polyimides, and polysulphones. a literature review is provided on the different ways of joining high performance thermoplastic composites by adhesive and fusion bonding the discussion on adhesive bonding includes examination of the performance of specific adhesive/thermoplastic combinations and of techniques for the preparation of composite surfaces: abrasion, etching, flame, and plasma treatments. thermoplastic composite welding techniques discussed in depth include the following: heated press welding, resistance welding, induction welding, and ultrasonic welding. works which examine or compare applications for these bonding techniques are also reviewed
