Study on Short Basalt Fiber Reinforced Fluorine Rubber Composites

Abstract

Fluorine rubber has excellent performance, such as cold resistance, heat resistance, ozone resistance thermal properties and so on. However, fluorine rubber is poor in the mechanical properties. In order to improve its availability of fluorine rubber, short basalt fiber/ fluorine rubber composite materials were prepared by using short basalt fiber as reinforcement, and its mechanical properties and compatibility were studied. The influence of the surface treatment on short basalt fibers, short basalt fiber content on the mechanical properties of short basalt fiber reinforced fluorine rubber composites were studied. The best formulation of short basalt fiber/ fluorine rubber composite materials were determined by testing Shore A hardness, tensile strength and elongation at break. The results show that the formula obtained best mechanical properties is 100 phr fluorine rubber, 10 phr short basalt fiber, and 2.5 phr KH-550. And further demonstrate that compatibility of short basalt fiber / fluorine rubber with KH550 is best by SEM and IR analysis. And prepare excellent performance of fluorine rubber composite materials.
