... The effect of physical aging on the creep response of a Radel X/IM7 thermoplastic composite was studied. Momentary tensile creep tests were conducted at increasing aging times following a rapid quench from above the glass transition temperature ( T g ) to a sub- T g aging temperature...

... composites showed significantly less matrix cracking and delamination and greater strength retention capability than the two epoxy-based composites. However, beyond a certain threshold velocity, the thermoplastic composites experienced a sudden drop in flexural strength, more so than the epoxy-based...

... models were developed to account for the load-frequency effect on fatigue life of thermoplastic composites. Temperature rise near the hole was included in the model to account for temperature effect. fatigue load frequency temperature thermoplastic composite E. Dan-Jumbo, 1 S. G. Zhou, 2...

... temperature and lower rates of deformation tend to enhance ductility in PEEK-based thermoplastic composites through fibril formation resulting from the breakup of crystalline lamellae. This ductility tends to stabilize the crack front, most likely through craze formation ahead of the crack tip, resulting...
