Abstract
Poly(arylene sulfide)/long carbon fiber laminates containing small amounts of added crack inhibiting agent such as polyethylene have reduced levels of microcracking. The polyethylene can be introduced as a finely divided powder in a slurry prepreg process or can be compounded with the poly(arylene sulfide) and extruded as a film for stacking with carbon fabric.
