Abstract: Under the action of dicumyl peroxide(DCP)vulcanization,the heat vulcanized phenyl-silicone rubber/boron carbide composites were prepared by using the synthesized heat vulcanized phenyl-silicone rubber as matrix,boron carbide as neutron absorbing materials and silica as reinforcing fillers.The molecular structure of synthesized rubber,the morphology,heat weight-loss rate and mechanical properties of composites were analyzed by Fourier transform infrared spectroscopy,scanning electron microscope,thermal gravimetric analyzer,hardness tester and electronic universal testing machine.The results showed that the synthesized rubber was based on Si—O—Si as the main chain,containing methyl,vinyl and phenyl pendant groups.Boron carbide were evenly dispersed in the composites.With the increase of boron carbide content,the shore hardness of composites gradually increased,while the tensile strength and heat weight-loss rate gradually decreased.The density,heat weight-loss rate and mechanical properties were improved to a certain extent by irradiation,and the greater the radiation dose,the more obvious the change.The composites could resist to high temperature of 450℃.
