Abstract
Disclosed herein are methods and fiber reinforced thermoplastic composition comprising: a polyaryletherketone (PAEK) component; a polyimide component, wherein the polyimide component comprises a blend of at least a first polyimide (PI) having glass transition temperature of at least 300° C. and a second polyimide (PI) having glass transition temperature less than the glass transition temperature of the first polyimide; and a reinforcement fiber component. The resulting fiber reinforced thermoplastic compositions exhibit improved mechanical performance.
