Effect of cocopeat and brass powder composition as a filler on wear resistance properties

Abstract

Abstract This hybrid composite is a combination of materials from cocopeat and brass powder as reinforcement with polyester resin as a binder. This hybrid composite is applied to disc pad product material. In the percentage of the composition will be affected of wear resistance of the product. The functions of disc pad as a brake where the principle works rubbing against the disc brake, it is necessary to have composite wear testing. This research method uses the ogoshi method on wear testing by varying the composition of the percentage of cocopeat and brass powder and in testing there are 2 treatments, namely dry and wet conditions. The results showed that sample 6 with a composition of 40% cocopeat and 60% brass powder had wear resistance of 3.3 x 10-6 mm2 / kg with a temperature of 41 °C in dry conditions and 2.02 x 10-6 mm2 / kg with a temperature of 40 °C wet. Wear resistance in sample 6 is higher than disc pad market and close to below the original market so that this composition can be recommended as a disc pad material.
