Notch Size and Loading Rate on the Tensile Behavior of Woven Fabric Reinforced Flexible Composite with Symmetrical Double Edge Notch

Abstract:

In order to investigate the effects of lager notch ratio (2α/W) and loading rate on the tensile behavior of woven fabric reinforced flexible composites, in this study, fracture mechanism and tensile strength of finite woven fabric-reinforced flexible composite materials with a through-the-thickness symmetrical located double edge notches is experimentally investigated, and the effects of notch size, loading rate on the tensile properties of notched specimen are analyzed. The results show that the woven fabric reinforced flexible composites exhibit notch sensitivity and loading rate dependent. These results play an important role in predicting strength and evaluating the lifetime of textile reinforced flexible composite materials with double edge notches.
