The relationship between the adhesive properties of the interphase of glass fiber/resin and the resultant composite Mode I interlaminar fracture toughness in glass cloth laminate was studied. The Mode I interlaminar fracture toughness of the laminate was obtained by the method of double cantilever beam (DCB) specimen. The delamination resistance of the laminates which have two silane coupling agents and two kinds of resin was discussed on the basis of interlaminar fracture toughness. The crack propagation behavior of DCB test was divided into stable and unstable manners. The fracture toughness and the crack propagation behavior were dependent on the types of silane coupling agents and resins. Mode I interlaminar fracture toughness of the laminate consist of glass cloth which was treated with silane coupling agents and fabricated with unsaturated polyester (vinylester) and epoxy(amine curing system) resin was measured.
