Experimental Investigation on the Physical, Mechanical and Thermal Properties of Chemical Treated Ramie Fiber-Based Non-Asbestos Organic Brake Friction Composites

Demands for reducing energy consumption and environmental impacts are the most important driving components for the development of ecofriendly fiber –reinforced composites in many fields. In contrast with synthesized fiber, natural fiber offers a number of advantages by way of biodegradability, light weight, low price, life-cycle superiority, and acceptable mechanical properties. The brake pad composites are created by utilizing the ramie fibers to search out the choice for brake industries. The composites are developed by increasing ramie fibers quantity between 5-20%. The outcomes of physic- mechanical and thermal properties reveal that tensile modulus, final compressive strength, failure strain energy, shear strength, flexural strength display good efficiency at 10wt% fibers contents in composites matrix and tensile strength, shear strength and proof stress exhibiting good efficiency at 15wt% fibers contents in brake pad composites. Thermal stability for hemp fibers composites enhances with increasing the fiber contents.
