The dispersion of carbon nanotubes/epoxy resin composite and the mixing processes of preparing carbon nanotubes/epoxy resin composite with dual-rotor mixer in bulk were studied.The results showed that carbon nanotubes could be dispersed in epoxy resin with dual-rotor mixer when the rotor speed was appropriate.Increasi…
The poly-p-phenylenebenzobisthoxazole(PBO) fiber is an organic fiber with very high tensile strength and modulus,and shows great potential in the reinforcement for polymer matrix composites.However,there is poor interfacial compatibikity between the PBO fiber and the polymer matrix due to the surface characters with o…
Using an integral safety analysis code,an accident analysis model for the vacuum vessel(VV),first wall(FW)/blanket,its primary heat transfer system and the pressure suppression system of ITER is built.The loss of coolant accident induced by the in-vessel first wall pipe double-ended rupture is selected with two differ…
Gelatin is the partial hydrolysis of collagen, and it is one of the important natural biopolymer materials. Traditional extraction process of gelatin exists long production cycle, low efficiency, energy consumption, environmental pollution and other shortcomings. In recent years, the development of environment-friendl…
