The molding process parameters of modified 5228A epoxy resin system specially used in RFI were studied by the manufacture of CCF300/5228A composite laminates. The RFI molding processes were divided into two basic processes: fiber infiltrated process and resin curing process. The viscosity-temperature characteristics, infiltrating pressure and compacting property of CCF300 fibrous material were studied during fiber infiltrated process. The curing kinetics and curing process parameters were discussed. Results show that the modified 5228A epoxy resin can meet the requirement of RFI process. The best fiber infiltrated process parameter of CCF300 reinforced modified 5228A composite is (125±3)℃, (0.1±0.02)MPa, 90min. The best curing process parameter is (0.5±0.02)MPa, (190±3)℃, 90min. The heating rate is maintained at 1~1.5℃/min in the whole process. ©, 2014, Chinese Journal of Aeronautics. All right reserved.
