Abstract
A process to form a fiber-reinforced composite having a continuous thermoplastic matrix of poly(arylene sulfide ketone) resins is provided. The composite is useful to form shaped articles with high temperature resistance. The composite can be prepared by consolidating under heating a multi-layer stack of resin sheets and fiber reinforcement sheets. The poly(arylene sulfide ketone) resins can be melt-stabilized through treatment with a water-soluble salt of an alkaline earth metal. The composite has excellent thermal properties such as heat distortion temperature.
