Abstract Technora fiber was surface modified by plasma treatment, and then characterized by means of scanning electron microscope and single fiber tensile strength tester in terms of the fiber surface morphologies and the properties of fiber itself, respectively. Then the influence of plasma treatment on the interfacial property of Technora fiber/epoxy resin in their composites in both room temperature dry (RTD) and elevated temperature wet (ETW) conditions was assessed based on the relevant values of interlamilar shear strength and water absorption. The results show that the plasma treatment had a great influence on the surface morphology of Technora fiber. Therefore, the interlamilar shear strength of Technora/Epoxy composites with the surface modified fiber is 24.93 MPa, which increases by 58.4% in comparison to 15.74 MPa for the composite with the as received fiber, correspondingly, the ability of water absorption of the composite decreased. However, the surface modification exhibits little effect on the property of the fiber itself. It is concluded that the surface plasma treatment of the Technora fiber is a significantly favored means for the enhancement of the interfacial performance of Technora fiber/epoxy resin within their composites.
