| Abstract: | Epoxy resin E51 has been modified with two kinds of polysiloxane, ATPS (Aminopropyldimethyl-terminated polysiloxane ) and PTPS (Phenyl-terminated polysiloxane). The chemical bonding between polysiloxane and epoy resin and the influence of the feature and structure of the modified resin to the physical aging phenomena of modified system have been studied. Using DSC method,the variation of internal stress of epoxy resin network during isotherm solidify and cooling process has been measured. The intrinsic con nection between the internal stress relaxation of the modified epoxy resin with its physical aging has also been discussed. |
