| Abstract: | The carboxyl-terminated flexible chain-extender was applied in epoxy resin/anhydride curing system to get the flexible epoxy resin cured on moderate temperature with high elongation at break. The influence of the flexible chain-extender content on the mechanical properties of the cured resin was investigated and discussed. The research results showed that more flexible chain-extender, less curing agent and adequate accelerator were helpful to increase the elongation at break of the cured resin. The elongation at break of the cured resin was up to 236 % and the tensile strength reached 6.08 MPa. |
