| Abstract: | Different kinds of organic silane,epoxy terminated two functional aliphatic polysiloxane,dihydroxyldiphenoxydimethyl silane and 3,3′,3″-trihydroxyldiphenoxydimethyl silane triglycidyl ether were synthesized.Mechanical properties of modified bisphenol F epoxy were studied,as well as thermal properties and the resistance to acid.It is showed that 3,3′,3″-trihydroxyltriphenoxy silane triglycidyl ether can improve the mechanical properties of the the cured epoxy resin,the thermal expansion coefficient below Tg reduces by 18.8%,the internal stress decreases by 22.8% and the crack resistance index increases by 52.2%.Meanwhile,Tg temperature hardly decreases.and the modified bisphenol F epoxy/glass fiber composite has improved resistance to acid,suitable for electronic application and discreteness of battery container,etc. |
