增韧改性环氧乙烯基酯树脂基复合材料界面性能的研究

he surface properties of the T300-6K, T700-12K carbon fibers and the S2 high-strength glass fiber , the chemical activity of the Swancor980 toughening modification of epoxy vinyl ester resin were characterized. The Interfacial properties of three fibers and their plain weave fabrics reinforced Swancor980 resin composites were tested and analyzed. The results showed that the interfacial shear strength and interlaminar shear stress of the single fiber and plain weave fabric of S2 high-strength glass fiber reinforced composite are better than the carbon fiber system. The interfacial properties of the T300-6K system and the T700-12K system were in the same range and the former is weaker than the latter.
