Abstract
Organic-inorganic hybrid coating was used to modify the surface of HSGF. Surface characteristics of fiber before and after coated were confirmed by X-ray photo electron spectroscopy (XPS) and atomic force microscopy(AFM),respectively. The effect of coating on acid-resistance of fiber was investigated by using immersion method. The interface bonding of composites was evaluated by interfacial shear strength test. The variety of mechanical properties of fiber and composites were measured using electronic universal-testing machine. Result shows that poly(methylphenylsiloxane) coating can effectively protect high silica glass fiber by preventing the harmful interface reaction and decreasing corrosion rate of phosphate to fiber. The flexural strength value of the composites with modified sizing is 32% higher than that of the untreated ones.
