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.

Mechanical properties of flexible composites reinforced with high-performance glass fiber multi-axial warp-knitted fabrics

“…Most of the research has been on the mechanical properties of woven fabrics, biaxial warp-knitted flexible composites and rigid composites formed by multi-axial warp-knitted fabrics. 30,31 There is less research on high-performance multi-axial warp-knitted stretchy composite. This paper uses environmentally friendly and high-tenacity TPU as the matrix of the composites and multi-axial warp-knitted glass fiber fabric as the fabric reinforcement.…”
