Wheat straw natural fiber used as Brake pad Reinforcement Polymer composite as asbestos free brake friction material

Abstract

The awareness towards the eco-friendly materials has increased the demand of natural fibers. The natural fibers have many advantages over the other materials like short growing time, easy availability, cheap, eco-friendly with good mechanical properties. W.H.O. has announced that trending material have many sides effect to environment and to human being. Asbestos has been already proven cause of many cancers. In this research Wheat straw natural fiber has used in brake pad as a brake friction material. The different percentage of Wheat straw 5-20% was used to develop new brake pad samples. The results of physio-mechanical properties reveal that tensile Modulus, ultimate compressive strength, impact energy, flexural strength showing good performance at 5 % polymer composites matrix, and ultimate tensile strength, shear strength and proof showing good performance at 10% fibers contents in brake pad composites. Thermal stability for Wheat straw fibers composites increase with increases the fiber contents.
