Abstract

In order to evaluate the fracture strength of a composite reinforced pressure vessel (CRPV), a full-scale vessel test is required by standards ASME BPVC-VIII-3-2017, and KHKTD 5202. However, such a test consumes a considerable amount of time and money. In evaluating the fracture strength of the CFRP layer using a plate specimen, there are some problems (e.g. stress concentration at the grip). In this paper, internal pressure burst tests using a small CRPV specimen were conducted in order to establish a method of evaluating the fracture strength of the CFRP layer.
