Abstract
The interphase between fiber and matrix has a very important role, which includes the load transmission between fiber and matrix. In this study, the effect of interphase characteristics on the various mechanical properties of plain woven composites were most concerned. Basic mechanical properties of plain woven fabric composites with flexible interphase were evaluated experimentally. Nonlinear stress-strain behavior in off-axis tests was characterized using 3 parameter plasticity model. Cyclic tensile tests were conducted to evaluate the effect of interphase thickness on the durability.
