Carbon fiber reinforced plastics are utilized in various structures because they have superior properties, such as specific strength, specific rigidity and so on. In order to spread applications of CFRP in the field of aerospace, an open hole compressive strength should be made clear. The open hole compression (OHC) strength of flat plates made of CF/Epoxy were obtained by several methods, for one example of SACMA SRM 3R-94 (SACMA). In this paper, a new test jig is proposed to use smaller dimension of test specimen in the case of comparison with SACMA's one and this jig is referred to as NAL jig. The experimental result of compressive strength for quasi-isotropic specimen shows the equivalent compressive strength obtained by both jigs and demonstrates the usefulness of the NAL jig in the OHC test.
