| Abstract: | The effects of different curing conditions on curing reaction of cyanate ester resins(CE)/epoxy resin(EP)(60/40) system and CE/EP/chemigum(A)(71/4/25) system,as well as the properties of the corresponding films were investigated.The curing degree increases with increasing heating time and temperature in both CE/EP and CE/EP/A system.The CE/EP film has poor flexility.The thermal stability of CE/EP/A film was increased with increasing heating temperature under the same heating time;the temperature of thermal decomposition was 367.3 ℃ for the film heated for 2 h at 110 ℃,130 ℃ and 150 ℃,respectively.The impact strength and flexility of CE/EP/A film prepared in this paper are 50 kg·cm and 15 mm.With increasing the heating temperature,the tensile strength and Young’s modulus of CE/EP/A film enhance,while its elongation at break decreased. |
