Fatigue behavior of long fiber reinforced polyamide and polycarbonate composites under tension-tension loading

Abstract

Static tensile strength and fatigue behavior of long glass fiber reinforced semicrystalline polyamide (Nylon 6,6) and amorphous polycarbonate(PC) composites were investigated. The static tensile measurement at various temperatures and tension-tension fatigue loading tests at various levels of stress amplitudes were studied. Two-parameters Weibull distribution function was applied to obtain the statistical probability distribution of experimental data. The temperature increasing phenomenon under tension-tension fatigue loading were compared between semicrystalline and amorphous composites.
