Abstract

Abstract: Thermoplastic carbon fiber composites have been widely used in fields such as aerospace and navigation because of their low density, high strength, corrosion resistance, and good plasticity. Ultrasonic welding has been proven to be one of the effective methods for conventional thermoplastic carbon fiber composites to achieve joint. Still, it is challenging to realize ultrasonic welding of poly(phthalazinone ether)resin/carbon fiber composites with a glass transition temperature of more than 280 ℃. In response to the ultrasonic welding requirements of the 0°/90° continuous stacking preparation process of this thermoplastic carbon fiber composite material, ultrasonic welding experiments on overlapping layers with three typical different fiber directions are carried out. The macro and micro structures of the ultrasonic welding interface and the bonding behavior of the ultrasonic welding interface are analyzed, revealing the influence of ultrasonic welding process parameters on the connection strength of this thermoplastic carbon fiber composite material. The key to improving the high strength of ultrasonic welding is to achieve the mutual embedding of laminated fibers under high pressure and welding heat is clarified. The research work provides reliable process parameters for ultrasonic welding of 0°/90° continuous stacking production line of the newly developed thermoplastic composite material.
