The characteristics of electron beam curing technique are rapid, effective and low cost It is found that the adhesion between carbon fibers and matrix of electron beam cured composite was lower than thermal cured composites So it is important to study the interface properties of electron beam cured composites In this paper, XPS,Raman were used to characterize the treated and untreated carbon fiber surface properties and ILSS testing method was used to evaluate the interfacial adhesion properties of the electron beam cured composites From the results it was shown that the trace water absorbed by the carbon fiber and void in the composite material play an important role in the interface properties of electron beam cured composites The interface properties of electron beam cured composite reinforced by carbon fibers were decreased by electrochemically treating with the ammonium bicarbonate, and increased by treating the carbon fibers with the electron beam curable coating
