A silicon-containing propargyl ether of bisphenol A (PSPE-A) was synthesized by the polycondensation of bisphenol A dipropargyl ether and chlorosilane, and a diacetylenic benzene end-capped silicon-containing propargyl ether of bisphenol A (DPSPE-A) was synthesized by two step method. Then the bis(triphenylphosphine) nickel dicarbonyl, octacarbonyl dicobalt, and bis(cyclopentadiene) cobalt were used to catalyze the curing of the PSPE-A and DPSPE-A resins, respectively, and a carbon fabric (T300CF) reinforced silicon-containing propargyl ether of bisphenol A resins was prepared. The thermal curing and thermal properties of PSPE-A and DPSPE-A were characterized by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic thermomechanical analysis (DMA), and the mechanical properties of the PSPE-A based composites were studied. The results show that end capping with diethynyl benzene can increase the thermal properties of PSPE-A resin. The three catalysts can all decrease the curing temperature of PSPE-A resin, and the initial curing temperature of PSAPE-A and DPSPE-A decreases by about 130℃ and 60℃ after using bis(cyclopentadiene) cobalt, respectively. The flexural strength of the cured PSPE-A and DPSPE-A is 35.8 MPa and 27.8 MPa, respectively. The flexural strength of T300 carbon fabric reinforced PSPE-A and DPSPE-A composites is 458.2 MPa and 287.6 MPa, respectively.
