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

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.

A Study on Characteristics of Brake Pad Composite Materials by Varying the Composition of Epoxy, Rice Husk, Al2O3, and Fe2O3

“…Consequently, Cu particulates remain firmly adhered to the matrix, resulting in less wear [63]. The findings in this study are supported by findings from other studies that show an increase in surface hardness is not always accompanied by an increase in the wear resistance of the brake pad material [56], [63]- [65].…”

Influence of Varying Concentrations of Epoxy, Rice Husk, Al2O3, and Fe2O3 on the Properties of Brake Friction Materials Prepared Using Hand Layup Method

“…The specific wear rates produced by the BP_6 specimen (8.67 × 10 −7 mm 2 /kg) are smaller than the specific wear rates produced in previous studies with specific wear rates of 6.9 × 10 −6 mm 2 /kg [ 98 ], 3.3 × 10 −6 mm 2 /kg [ 91 ], and 2.02 × 10 −6 mm 2 /kg [ 91 ]. Nevertheless, the specific wear rates produced by the BP_6 specimen are greater than those of commercial products.…”

“…A smaller specific wear rate, meaning that less material is worn or removed from the material’s surface in the same amount of time, indicates that the material is more wear-resistant. Therefore, the lower the specific wear rate, the higher the material’s wear resistance [ 90 , 91 , 92 ].…”

“…Nevertheless, the specific wear rates produced by the BP_6 specimen are greater than those of commercial products. The specific wear rates of commercial products are 6.5 × 10 −7 mm 2 /kg and 5.9 × 10 −7 mm 2 /kg, obtained during wear tests in dry and wet conditions [ 91 ].…”

Karakteristik Kekuatan Tarik Dan Morfologi Biokomposit Pelepah Pisang Raksasa

“…Sedangkan sehelai serat pelepah pisang raksasa mempunyai panjang serat ratarata 20 cm dengan berat 0,0704 gram. Dari mechanical property yang terdapat didalam pelepah pisang raksasa ini memungkinkan mempunyai tensile strength yang tinggi jika dijadikan sebagai bahan komposit dengan matrik polyester (Wani, R.S., 2017;Setyawan et al, 2020).…”
