抄録

Interlaminar fracture behavior of hybrid composites with non-woven carbon tissue is investigated under a Mode I loading condition with a DCI5 specimen. Hybrid composites are made by inserting non-woven tissue between prepreg layers. Two kinds of specimens are prepared from [0]24 and [012/ 012]. Here, the symbol "/" means that non-woven carbon tissue is located at a 0/0 mid-plane of the specimen. An initial interlaminar crack is introduced to a mid-plane of the specimen. Interlaminar fracture toughness (GIc) of hybrid composites is compared with that of CFRP. GIc of hybrid composites is almost dependent on only that of matrix resin. The fracture surfaces of the specimens are observed with an optical microscope and SEM, and the failure mechanism is discussed.
