積層構成がFW製FRP円筒のエネルギー吸収特性に及ぼす影響

抄録

GFRP is expected to be used as automotive components because it has high specific strength and failure strain, and its cost is lower than CFRP. We fabricated GFRP cylinders by a filament winding method and the drop weight impact test was carried out. As a result, the specific energy absorption capability of GFRP cylinders using a high strength glass fiber was almost same values of CFRP cylinders. In this study, in order to investigate the effect of lamination constitution of GFRP cylinders on energy absorption property, GFRP cylinders with the first layer and the second layer wound at different angles were fabricated and the drop weight impact test was carried out. The test results showed that the specific energy absorption capability of specimens with different angles were higher than those of specimens with same angles.
