ABSTRACT
For the purpose of estimating the bond strength between fiber and matrix resin in CFRP, T-Peel test method have been developed by us. This test is extremely easy compared with DCB and WTDCB tests. It is clarified that there is a correlation between the peel strength and fracture energy and the T-Peel test can be used as a screen test for the fracture toughness and bond property of the CFRP.
