摘要
用碳化硅晶须、光敏树脂合成了光固化用树脂基复合材料,并对材料进行了拉伸测试,测试结果表明复合材料的实测拉伸强度与理论值相差较大;在实验的基础上进一步建立了复合材料的界面相模型,采用有限元方法分析了界面性能对晶须增强树脂基复合材料力学行为的影响.结果表明:界面性能对晶须承受轴向应力的影响远大于对树脂基体的影响,晶须界面剪切应力与界面结合强度成正比,晶须端面应力集中系数随界面结合性能的增强而递增.
The Resin matrix composites were synthesized by SiC Whisker and photosensitive resin.The tensile strength of the composites was tested. The test results show that there is a great discrepancy between the measured tensile strength and ideal tensile strength.Based on the experiment,the interface phase model was built and the finite element method was applied to analyze the effects of interfacial properties on mechanics behavior for whisker reinforcing resin matrix composites.And the conclusions are as follow:The interfacial properties' effect on axial stress of whisker is greater than its effects on resin matrix;The interfacial shear stress of whisker is linear with the intensity of interfacial properties;Along with the intensity of interfacial state,the coefficient of stress concentration is increasing by degree.
