AbstractA specific non-hole compressive (NHC) test method for advanced composite materials has not been widely authorized even now because of the essential difficulty of NHC tests. In this study, standard test methods such as SRM-1 (SACMA), Celanese (former ASTM D3410 A-method), ASTM D695, ASTM D6484 (SRM-3), ASTM D6641 (CLC), JIS K7076 (A method) were evaluated for three kinds of quasi-isotropic carbon/epoxy composites (CFRP). Furthermore, two kinds of original compressive test methods, i.e.NAL-I, II, were proposed. It was revealed that SRM-1 and ASTM D6641 (CLC) are more adequate than any other standard methods from the view point of reliability, repeatability ad efficiency. It was demonstrated that the experimental results obtained by NAL-II method were similar to those by SRM-1 and ASTM D6641.
先進複合材料の無孔圧縮試験法に関しては試験自体の困難さも相俟って、特定の試験法が幅広く認知されている状況とはなっていない。本研究では、3種類の炭素繊維エポキシ複合材料擬似等方積層板を対象として、SRM1、Celanese(旧ASTM D3410)、ASTM D695、ASTM D6484(SRM3)、ASTM D6641(CLC)、JIS K7076(A法)で規定された試験法の相互比較を行った。併せてJAXA独自の方法としてNAL-I法およびNAL-II法を提案した。その結果、信頼性、再現性、効率性の観点から、SRM1とASTM D6641(CLC法)が他の方法よりも適切であることが確認された。また、NAL-II法でもこれらの方法とほぼ同じ試験結果が得られることが実証された。
