The effect of the addition of submicron glass fibers into the matrix of curved thin shell of CFRP in thickness direction on the energy absorption during out-of-plane impact was investigated with four types of specimens. Four types of CFRP shells were prepared in which each shape was: (a) flat plate (b) half-cylinder (c) low wide elliptical half-cylinder (d) high wide elliptical half-cylinder. The results showed that improvement of impact energy absorption was obtained for thin shell specimen with curved geometry as well as that for flat plate by adding submicron glass fiber into the matrix. This study found that design with half-cylinder CFRP shell is rather effective to utilize the result of modification with submicron glass fibers previously added into the matrix where the impact energy absorption was improved. |
