Modified Epoxy Resins as the Matrices for High Performance Glass Fiber Reinforced Composites
Glass fiber reinforced composites have many engineering applications due to their good mechanical performance. Epoxy resins are the popular matrices for fiber reinforced composites. In this paper, a traditional epoxy resin system, namely diglycidyl ether of bisphenol-F (DGEBF)/diethyl toluene diamine (DETD), was used as the starting material for the matrix. Multiwalled carbon nanotubes (MWCNTs) were employed to modify the epoxy system and then CNT/epoxy nanocomposites were used as the matrix to fabricate glass fiber reinforced composites. Meanwhile, a reactive aliphatic diluent named n-butyl glycidyl ether (BGE) was also employed to toughen the epoxy system and the toughened and modified epoxy system was used as the matrix. Finally, different matrices were prepared for glass fiber reinforced composites and the tensile properties of the fiber reinforced composites were investigated. The results showed that introduction of MWCNTs and BGE led to the enhancement in the composite tensile strength. Especially, by the introduction of only 0.S wt％ content of MWCNTs and 10 phr BGE, the tensile strength of the glass fiber reinforced composites was significantly increased by 31.1 ％.
