Original Abstract

The study is aimed at preparation of glass fiber reinforced polymer composites with controlled interphase formed by plasma-polymerized tetravinylsilane and tetravinylsilane/oxygen thin film. The polymer films of specific physicochemical properties and thickness were deposited to improve interfacial adhesion of GF/polyester composites. The fiber surface was modified by using plasma enhanced chemical vapor deposition (PECVD) in low-temperature pulsed RF plasma operating in an effective power range of 0.1 – 10 W and different treatment time. The process of plasma-polymerization was preceded by pretreatment, improving the film adhesion using oxygen and argon gasses or their mixtures. Pretreated surface of glass fibers was modified by single and double layer of plasma-polymerized thin film. Mechanical response of plasma interlayers was evaluated by direct method of testing the interfacial shear strength using unique ITS (Interfacial Testing System) apparatus developed by Dow Chemical Company (USA). The interfacial adhesion of unsized, industrially sized, and plasma coated fibers was compared. The interfacial shear strength of optimized pretreatment and plasma coating shows an increase of 36% compared to the industrial sizing. Test results were examined in relation to the interlayer thickness and interlayer modulus.
