Purpose – The purpose of this paper is to investigate use of colemanite (C) upon friction and wear performance of automotive brake lining. Brake lining production with the boron product colemanite addition and braking characterization investigated for development of non-asbestos organic (NAO) brake lining because of negative effects on human health and environmental hazard of asbestos containing linings. During the braking, brake lining is warmed up extremely due to friction, and the high temperature causes to decreasing of breaking performance. Colemanite has high melting temperature, and this makes this material valuable for brake lining. Design/methodology/approach – This study investigated the effect of colemanite (C) upon friction and wear performance of automotive brake lining. Based on a simple experimental formulation, different amounts of boron product colemanite were used and then evaluated using a friction assessment and screening test. In these specimens, half of the samples (shown with H indices) were heat treated in 4 h at 180°C temperature. Friction coefficient, wear rate and scanning electron microscope for friction surfaces were used to assess the performance of these samples. Findings – The results of test showed that colemanite can substantially improve properties of friction materials. The friction coefficient of friction materials modified with colemanite varies steadily with the change of temperature, and the wearing rate of friction materials is relatively low by using colemanite. Heat treatment-applied samples (CH) have provided a higher and stable friction coefficient. These results indicate that colemanite has ideal application effect in various friction materials. Originality/value – This paper fulfils an identified information and offers practical help to the industrial firms working with brake lining and also to the academicians working on wear of materials. Parallel results have been presented between previously reported and present study, in view of brake characteristics and wear resistance. Use of the lower cost and productive organic sources of material are the main improvement of the present study.

Friction material is essential for automotive braking system. Based on previous study of existing friction material problems, hybrid biological fiber-reinforced resin-based friction materials (HBRMs, from the reinforced fiber component of resin-based friction materials) were explored in this study. Bamboo fiber, jute fiber and wool fiber (all have length of 3-5 mm) were processed to make three types of HBRMs and considered as three factors of biological reinforced fiber in test using orthogonal experimental design. Each factor had three levels of 1%, 2% and 3% fiber mass fraction while the ratio of other raw materials remains unchanged. According to the orthogonal experimental design table, nine formulations (denoted as M1-M9) were determined to test the HBRMs. For comparison, non-bio-fiber reinforced friction material (NBM) was added in the test. The properties of the HBRMs tested included Rockwell hardness, impact strength and density. The friction and wear performance of the braking materials was examined by a speed friction tester. The results show that the friction coefficient of the HBRMs was slightly higher than that of the NBM, indicating biological fibers affected the friction coefficient. The friction coefficient of the HBRMs decreased firstly with the increase of temperature and had the lowest value when the temperature reached 300°C, and it increased then as temperature increased. During recovery process, the friction coefficient of the HBRMs firstly increased with the decrease of temperature and then decreased greatly when the temperature dropped to 100°C. The wear rates of the HBRMs increased with the increase of temperature and reached maximum value when temperature reached 200°C, then it decreased with the increase of temperature. The results of fuzzy comprehensive evaluation analysis on the friction coefficient and wear rate show that the best comprehensive properties were presented when the mass fraction of bamboo, jute and wool fiber were 3%, 3% and 1%，respectively.
