Abstract
Transverse-compressive and interlaminar shear tests on a epoxy GFRP laminate, which had plain woven glass fiber, were conducted over a temperature range from R.T. to 200℃. Moreover, fatigue tests under compressive and compressive/shear loading were performed over a wide range from 10^2 to 10^7 cycles at R.T. and 150℃. The transverse-compressive and interlaminar shear strengths decreased with increasing temperature. The interlaminar shear strength was about one tenth of transverse-compressive one. The obtained fatigue S-N curves were approximately linear for all test conditions. The fatigue strengths of compressive and compressive/shear tests were arranged well using maximum shear stress than principal stress.
