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.
