摘    要:为获得一种碳纤维二维正交平纹机织布增强树脂基复合材料准静态和动态下的层间拉伸力学性能,对垂直于碳布平面方向 ( 横向),分别利用Instron试验机和SHTB实验技术,进行了准静态拉伸和动态拉伸实验。得到了从低应变率 (10-3/s) 到较高应变率 (约3×102/s) 下的拉伸应力-应变曲线和拉伸强度。通过分析发现,拉伸破坏总是发生在相邻铺层的层间界面处,层间拉伸模量和拉伸强度都具有一定的应变率强化效应,但是层间拉伸破坏应变几乎不存在应变率效应。

关 键 词:碳纤维  平纹机织  层间拉伸  动态性能  SHTB

Abstract:To achieve the interlaminar tensile properties for a kind of carbon fiber two-dimensional orthogonal plain woven reinforced polymer matrix composite, numbers of quasistatic and dynamic tensile experiments in the through-thickness direction of the composite were conducted, by means of Instron apparatus and SHTB technology respectively. The tensile stress-strain curves and tensile strength were achieved in a large strain rate range ( from 10-3/s to 3×102/s). The experimental results show that the failure is bound to occur at the interlaminar of neighbouring carbon cloth. The tensile modulus and tensile strength increase slightly under impact loading, and the tensile failure strain is nearly independent of the strain rate.
Keywords:carbon fiber  plain woven  interlaminar tension  dynamic properties  SHTB
