Application of Basalt Scale (BS) Filler and Fluorides Graphite (FG) Reinforced Textile Composites in Friction and Wear at High Sliding Speeds

A novel binary combining Basalt scale (BS) filler and Fluoride Graphite (FG) was introduced into the fabric composites. In the view of high-speed tribological applications, the related characteristics of obtained composites were comparatively explored. The mechanical properties of composites showed the addition of BS filler and FG increased the tensile modulus and the elongation simultaneously. On thermal properties aspect, the thermal stability of composites was improved while the thermal conductivity also decreased by the fillers system. Finally, the high-speed friction behaviors of modified composites disclosed, Basalt Scale (BS) filler could solely release from the composites to compact into the tribofilms or supply the milling impact to help the in-situ partly exfoliation process of Fluoride Graphite (FG). Under 10 MPa and 0.98 m/s, the wear tests showed that the wear rate of Composite B(filling 0.5% BS filler) decreased by nearly 32% than pristine composite. Under 50 MPa and 1.18 m/s, the even tougher wear tests further showed that the wear rate of Composite C(filling 0.5 % BS fillerand 3% FG) decreased by nearly 53% than pristine composite.
