摘要：

The effect of amine/epoxy ratio on the fracture toughness(K-Ic) of tetrafunctional epoxy resin was investigated. K-Ic value was measured by single-edge notch-bend test. The K-Ic value of the tetrafunctional epoxy resin increased with increasing the amount of amine curing agent. This result was explained with the structural viewpoint of the epoxy network. The network structure of the tetrafunctional epoxy was analyzed with dynamic thermomechanical measurement and in-situ near IR technique.
