| Abstract: | Two kinds of epoxy resin systems R2511 and R2512 were prepared to obtain the appropriate system for carbon fiber reinforced composites.The processing property,curing characteristics and mechanical property of the composites by using RTM molding has been investigated thoroughly.The results show that the two kinds of systems own the good operating window with low viscosity.The optimum operating temperature of R2511 system using RTM ranged between 40 ℃ and 50 ℃,while the room temperature was more suitable for R2512.The activation energy of R2511's 72 kJ/mol,while R2512 have the lower value 62 kJ/mol.As to the overall mechanical property of composites,R2512 was also superior to R2511 system.Therefore,the two kinds of resin are suitable for epoxy resin systems with different operating temperature. |
