MECHANICAL PROPERTIES OF MODIFIED EPOXY RESINS AND THEIR GLASS FIBER REINFORCED COMPOSITES

摘要：

Diglycidyl ether of bisphenol-F (DGEBF)/diethyl toluene diamine (DETD) was used as the starting matrix.The reactive aliphatic diluent (n-butyl glycidyl ether,BGE) was employed as the soft modifier and the multiwalled carbon nanotubes (MWCNTs) were employed as the stiff modifier to modify the epoxy matrix.The mechanical properties of the modified epoxy system were examined first for optimizing its formulation.Then,the modified epoxy system was used to prepare glass fiber reinforced composites and the tensile,flexural and interlaminar shear properties of the fiber reinforced composites were investigated.It is shown that the introduction of BGE and MWCNTs led to the remarkable enhancements in the mechanical properties of the composites.This observation is explained by the variance in the fiber-matrix interfacial adhesion strength before and after the introduction of the modifiers.
