| Abstract: | A new toughening agent CC is applied to the epoxy resin to improve the toughening property and then a kind of low viscosity medium temperature solidified epoxy resin is attained.The mechanical property of the epoxy resin is tested,and the structure and properties are studied by FTIR and DMA.The results show that the shear strength and tensile strength of epoxy resin are the apex of 25.1 MPa and 55.88 MPa with CC content of 19wt%.The epoxy resin has a low viscosity.The reaction is complete during solidifying process.The stiffness of epoxy resin is pretty big,and Tg reaches 110.36 ℃. |
