Abstract

In this paper, a high-friction composite material based on the combination of binder, friction modifiers, fibers and fillers is investigated. In the binder, up to 20% of phenol are replaced by cardanol with various weight ratios of 100/0, 95/5, 90/10, 85/15, 80/20. Cardanol may react both through the phenolic group and the double bond of the side chain yielding addition, condensation and polymerisation reactions that allow the synthesis of tailor-made products and polymers of high value. In the present work, mechanical, thermal and wear characteristics of cardanol based phenolic resin with organic ingredients were manufactured and tested. An analysis of microstructure characteristics of composites was carried out using scanning electron microscope. The effect of environment on the composite was investigated in water, salty water and oil. The results showed that the addition of cardanol reduces the wear resistance and increases the compressibility which reduces the noise propensity.

Highlights

  • Designing composite friction material is often based catalysts or by the functionalization at the hydroxyl on experience or a trial and error method to make a group and subsequent oligomerization to obtain a new formulation

  • The results showed that the addition of cardanol reduces the wear resistance and increases the compressibility which reduces the noise propensity

  • Porosity of Cardanol Phenol Formaldehyde (CPF) composite is high which is an important factor for friction material such as noise dampening and wear resistance[17,18]

Summary

Introduction

Designing composite friction material is often based catalysts or by the functionalization at the hydroxyl on experience or a trial and error method to make a group and subsequent oligomerization to obtain a new formulation. Mechanical, thermal and wear characteristics of cardanol based phenolic resin with organic ingredients were manufactured and tested. Phenolic resin is used as binder in friction materials due to their low cost and good combination of mechanical Experimental work properties, such as high hardness, compressive strength, moderate thermal resistance, creep resistance and very good wetting capability with most ingredients[4].
