Popis: tert-butyl peroxy benzoate (TBPB)/acrylated epoxy soybean oil composite(AESO) composite was prepared by immersion compression for-ming technology, and its curing process and structure were investigated. The results showed that the reaction activation energy of TBPB/AESO composite calculated based on Kissinger method and Starink method was 78.803 kJ/mol. Sesthk-Berggren was selected as the curing model, and the calculated curing kinetics equation based on the Malek method fitted well with the experimental data. The optimized curing process of TBPB/AESO involved increasing slowly the temperature to 407 K, then increasing rapidly the temperature to 424 K for constant temperature curing, and finally increasing slowly the temperature to 489 K for a certain period of time.
