Критерии разрушения образцов из полимерных композиционных материалов при резонансных усталостных испытаниях

Abstract

Has been analyzed the fatigue damage of samples made from polymer composite material with different reinforcing. An analysis of fatigue damage samples is based on the process of damage accumulation in multiply laminate. Has been observed the longitudinal cracking during to fatigue tests of unidirectional samples as well as longitudinal delamination during to fatigue tests of multidirectional samples. The transverse failure is observed to be caused by the failure of longitudinal fibers during to fatigue tests of cross-reinforced samples.
