Ultrasonic treating system is used to improve, continuously and on-line, the wettability between quartz fiber and epoxy during the process of impregnation. According to the technique feature of preparing quartz fiber/epoxy composites, we establish the ultrasonic treating system. It includes vibrating system, which consists of piezoelectricity transducer and amplitude-transformer, and ultrasonic generator with functions of tracking, velocity stabilizing and current overload protecting. Effects of ultrasound on surface morphology of quartz fiber/epoxy composites are studied. The difference of composite surface between not treated and after treated by ultrasound is watched by SEM and Metallurgical Microscope. The results show that the ultrasound does improve the wettability between quartz fiber and epoxy resin.Acknowledgement: This work was supported by 'the Fundamental Research Funds for the Central Universities', DL10BB19; and �the Natural Science Foundation of Heilongjiang Province, China(Grant No.ZD200914).
