A kind of high strength and high modulus fibre was prepared by means of plasticized melt spinning of high molecular weight polyethylene ( HMWPE) with wax blend and high stretch ratio. 采用石蜡增塑高相对分子质量PE后纺丝并经高倍拉伸制备高强高模纤维。
However, the shear modulus varies greatly with the change of inflation pressure to longitudinal stretch ratio. 剪切模量不随剪应力和剪应变的变化而变化,改变轴向伸长比和透壁压将使剪切模量产生变化。
In the process of elongation at a fixed transmural pressure, the shear modulus was non-linear as function of the longitudinal stretch ratio and strain. 在透壁压一定的伸长过程中,剪切弹性模量与轴向伸长比、轴向应变呈非线性关系。
