TENSILE DEFORMATION AND DAMAGE ACOUSTIC EMISSION MONITORING OF CARBON/ARAMID HYBRID WOVEN COMPOSITES

Abstract

Abstract: Carbon/aramid hybrid fiber woven fabrics were used to prepare composite laminates by different layering methods. In order to study the damage evolution of carbon/aramid hybrid woven composites during tensile process, tensile loading tests of the composites were monitored by using acoustic emission (AE) and digital image correlation (DIC) complementary techniques. According to AE signals and the surface displacement fields of the composites during the tensile loading, AE response characterizations and variation of surface deformation fields of carbon/aramid hybrid woven composites were analyzed. The results show that the amplitude attenuation in the carbon fiber direction is lower than that in the aramid fiber of the composites. In the case of type-A specimens, when the specimens are loaded in carbon fiber and aramid fiber direction, the highest tensile strength and toughness can be obtained, respectively. The tensile strength of type-B composite specimens is higher than that of type-A in the direction of aramid fiber, while the toughness is better than that of type-A in the direction of carbon fiber. The deformation and damage characteristics of composite laminates are clearly reflected by surface deformation fields. AE and DIC complementary technologies provide an effective method for nondestructive testing, damage assessment and health monitoring of the composites.
