Abstract

A GFRP butt-joint was formed between two adherends of an aluminium pipe by winding a wetted roving of glass fiber with epoxy at ±45° angle. The butt-joint was studied through two kinds of tests: tensile and bending. The specimens were of two types: thin and thick GFRP sleeve. In tension tests, the thin sleeve specimens failed due to the failure of the GFRP sleeve at the joint plane as the axial stress developed in the GFRP sleeve exceeded its ultimate strength. However, the thick sleeve specimens resisted higher load but one of the two adherends slipped out of the GFRP sleeve. In bending experiments, the failure in specimens with a thin GFRP sleeve occurred due to the breakage of the sleeve at the joint plane. However, the specimens of thick GFRP sleeve did not fail within the sleeve. Numerical analysis using ANSYS was carried out to explain the experimental results.
