Burst test of Type-3 FW vessel (normal working pressure: 19.6MPa, capacity: 2.1L) wound with and without GFRP layer were examined. Observing the cross section of the CFRP layers, microscopic structures such as fiber volume fraction Vf and the edge part of the hoop layer was measured. Analyzing the stress by FEM model considering inhomogeneity of fiber packing the burst pressure was predicted.
