仿球鼠妇骨片结构针织物的制备及其性能
Preparation and performance of bio-inspired tergite structure knitted fabrics
摘要
Abstract
To address the issues of excessive weight and poor flexibility in existing impact protective equipment,the tergite structure of the armadillidium vulgare exoskeleton served as a biological prototype.Using high-performance aramid filaments as the raw material,integrated knitting of the bio-inspired tergite structure fabric was achieved via a stitch-transfer technique on a flat knitting machine.Mechanical property tests and damage morphology analysis were conducted on the fabric.The results show that the knitting process was improved by adjusting fabric density,adding drop-off actions to the needles on the front bed that did not form loops during tergite structure knitting,and applying sinker actions to the needles on the back bed that carried two loops,along with adopting a low knitting speed.The fabric exhibited good flexibility.The bio-inspired tergite structure knitted fabric demonstrated excellent tensile,tear,and bursting properties.It also showed outstanding low-velocity impact resistance.Under impact from a flat hammer,the fabric performed best,followed by the spherical hammer,and then the conical hammer.The front side of the fabric exhibited better impact resistance than the back side.The damage was mainly characterized by out-of-plane bulging along the loading direction and varying degrees of failure at stress concentration zones.关键词
