Using bisphenol A epoxy resin (E-51) as the matrix,silane coupling agent γ-(2,3-epoxypropoxy) propyltrimethoxysilane (KH560) surface-treated corn straw particles (KHCS) as modifier,and 2-methylimidazole (2-MI) as curing agent,epoxy resin composites were prepared.With the help of Fourier Transform Infrared (FT-IR),Scanning Electron Microscope (SEM),and Differential Scanning Calorimeter (DSC),the properties of epoxy resin composites were characterized and analyzed.The results showed that,compared with corn straw particles without surface treatment,the interface force between corn straw particles and E51 treated with KH560 was enhanced,and the compatibility between the two phases was improved;furthermore,the toughness of epoxy resin was obviously improved by surface treated straw particles.
