Abstract

Herein, a facile method is developed to fabricate the three novel blends consisting of Polyamide-imide/Cyanate ester resins (PAI/CE), Kane Ace MX451/Cyanate ester resins (MX451/CE), and Polyamide-imide/Kane Ace MX451/Cyanate ester resins(PAI/MX451/CE). It was found that the fractured surface of PAI/CE presented an ordered micro-stratified morphology with parallel and regular arrangement. By means of the copolymerization of PAI and CE, the fracture toughness and tensile strength of cyanate are significantly improved. In addition, the PAI modified cyanate ester has the lowest water absorption rate and the lowest total mass loss rate. It is paving a way for designing and manufacturing thermoplastic polymer-based composite for high-performance toughing applications.
