摘要：

An SEM observation to support that PU-GFRP has higher toughness than PI-GFRP is presented. This is due to good interfacial bonding between the fiber and the matrix during the crack growth process. It is found that the GHc values derived from the ENF test failed to show the difference in the crack growth resistance between PI-GFRP and PU-GFRP. Hence, results from the ENF test should be treated with caution when used for evaluation of delamination resistance for fiber composites.
