An investigation is performed on the interfacial control of Glass/Polypropylene composites using polypropylene (PP) sheet treated by oxygen plasma. All T-peel tests for each treated specimen are carried out using an Autograph materials testing machine in order to estimate the strength of the interlaminar between the glass fabric and the PP resin. To determine the factors for controlling interfacial bond properties and delamination processes from the test results, two parameters were used, i. e. T-peel strength : calculated from tensile peaks in tension-displacement diagrams and T-peel amplitude : calculated from tensile alternations in it. The present plasma treatment increases the T-peel strength and amplitude about 50% and 120% higher than non-treated spacimens, respectively. These results that the properties of the interface between the fiber and the resin were effectively improved by this process. It was found that the T-peel strength was related to the surface energy of the PP sheet, which was calculated from the contact angle of distilled water. The T-peel amplitude was related to the fracture morphologies of the delamination surface.
