Tension-tension fatigue behavior of hybrid glass/carbon and carbon/carbon composites

Abstract This work investigates the quasi-static, low-cycle and fatigue behavior of hybrid glass/ultra-high modulus carbon (GC) low modulus/ /high (CC) fiber composites. These pseudo-ductile unidirectional interlayer hybrids are a new type composites whose potential is not yet fully understood, particularly under cyclic/fatigue loading. Different test methods (digital image correlation, video extensometer thermal camera) were used to record evolution strain, damage temperature during The results quasi-static loading shown responses with multiple fractures for all series. CC specimens exhibited higher initial elastic modulus, ‘yield’ stress strength, while GC showed highest strain. Much capacity resist was observed. In significant accumulated loading, when in different layers developed delamination between glass layers.
