Abstract
This study aims obtain a precise strength of a glass fiber/ epoxy resin interface by taking non-elastic analysis which might be very important factor to be considered. A cruciform specimen method is one of the reasonable tests to investigate interfacial strength. Varying the cruciform angles, the interfacial failure criterion under combined stress-state can be obtained. However, when the interfacial strength is beyond the matrix yield stress, non-elastic stress analysis must be done in order to obtain the interfacial strength precisely. In this study, the non-elastic analysis is performed and the effect is discussed.
