PURPOSE: To prevent wear due to the frictions of strands with each other and to improve the durability of rubber and cord composite material by embedding fiber cord made of fiber filament bundles, etc., obtained by coating the surface with a fiber adhering composition containing a solid fine particle lubricant and drying it in a rubber structure. CONSTITUTION: A rubber and cord composite material used for a conveyor belt, a tire, etc., is formed by embedding a fiber cord formed by twisting a fiber filament bundle and/or strands obtained by coating the surface with a fiber adhering composition containing a solid fine particle lubricant and drying it or a fiber cord treated with an adhesive in a rubber structure. As the lubricant, graphite fine particles and molybdenum disulfate, or a mixture of the graphite fine particles and the molybdenum disulfate are used. Aromatic polyamide fiber is used as the fiber filament bundles and/or the strands. |
