摘要 

基于单调和循环加卸载实验,测试获得了不同加载过程中2D-C/SiC复合材料在纤维束轴向方向上的泊松曲线,并对比分析了轴向损伤演化进程对材料泊松效应的影响。结果表明,在拉伸损伤加剧过程中,材料表现出显著的负泊松比行为;在加载损伤停滞状态下,材料则表现为近似线性正泊松比行为。加载过程中材料的泊松效应随着损伤程度的增加而不断减弱。结合扫描电镜断口结果分析可知,拉伸损伤加剧过程中材料内部沿加载方向上不断产生的基体开裂和界面脱粘损伤引起的材料沿垂直加载方向上的伸长变形,大于并掩盖了拉伸载荷在垂直加载方向上引起的弹性收缩变形,是导致2D-C/SiC复合材料表现出显著负泊松比行为的主要原因;加载损伤加剧过程中产生的大量开裂损伤导致的材料整体连续性的降低是导致其泊松效应不断减弱的主要影响机制。

Abstract

By using monotonic and cyclic loading tests, the Poisson curves along the fiber bundles directions of a 2D-C/SiC composite were obtained during various axial tensile and compressive loading processes. And the effects of axial damage evolution process on the Poisson effect of composite were studied. The results show that composite shows significant negative Poisson's ratio behaviors with increasing tensile damage during loading process, but the Poisson's ratio behaviors become almost linear and positive when the damage evolution process stops. In addition, the Poisson effect becomes weaker with increasing damage degree within composite. The SEM (scanning electron microscope) analysis results of fractured surfaces on tensile specimens indicate that, during tensile damage evolution process, the matrix cracks and interface debondings occurring along the loading direction will generate vertical extension deformation on composite, which is large enough to cover up the transverse elastic Poisson contraction caused by applied tensile load, so 2D-C/SiC composite shows significant negative Poisson' ratio behaviors. And the weaker Poisson effect of composite is mainly caused by the increasing discontinuity of composite, which is caused essentially by increasing cracking damage during tensile damage evolution process.
