【摘要】 为了探讨纳米材料对纳米功能锦纶力学性能的影响,比较研究了纳米功能锦纶、光电子锦纶和普通锦纶的强度、伸长率、断裂比功、初始模量、松弛性能和弹性回复率等力学性能。结果表明,纳米功能锦纶与普通锦纶相比,前者的强度、伸长率和断裂比功小,而初始模量和弹性回复率大;日晒对纳米功能锦纶的断裂强度和断裂伸长率影响较小,对其初始模量影响较大;纳米功能锦纶和普通锦纶的应力松弛曲线形状相似,日晒后,前者的松弛速度明显大于后者。更多还原

【Abstract】 An investigation of the effect of nano-material on the mechanical properties of nano-nylon fiber was carried out,and a comparative study between the nano-nylon,photo-electronic nylon and ordinary nylon was made in terms of the strength,elongation rate,breaking energy,initial modulus,relaxation and elastic recovery.The experiments showed that in compared with the ordinary nylon,the nano-nylon has lower strength,elongation rate,and breaking energy but higher initial modulus and elastic recovery.They have similar curves of relaxation of stress.The sun light has little influence on nano-nylon’s breaking strength and elongation rate while its initial modulus has been impacted greatly.In respect to the relaxation velocity,the sunlight has greater influence on nano-nylon than on the ordinary nylon.更多还原
