Influence of volume fraction from brake linings to the flexibility behavior and internal energy

Abstract

       The purpose of this research is to study the effects of volume fraction on the flexibility behavior and internal energy of brake linings with different constituents of material of the brake lining and pads. They were divided into 3 types as follows: type A, type B and type C respectively. These three kinds of composite materials consist of fiber, lubricants, copper and other. The testing procedure referred on JIS D 4413:1998 (7). In this condition can be simulated the testing by multi-state changing pressure, loop pressure and one-step changing pressure. The reduction and the deflection of thickness on the sample due to the compression forces and temperatures were measured. The results of experiment discovered to the flexibility behavior of all samples are also same to the tendency. By the sample type C of linings and pads, given to the maximum flexibility behavior with the highest of fiber composition. In term of the internal energy by volume of all samples depended on the proportion of lubricant and increased with high temperature. By the sample type A has the lowest of lubricant was given to the maximum internal energy by volume.
