“…Solving the problem of increasing the tribological reliability and durability [1,2] of tribocoupled elements of car parts requires a comprehensive approach [3]. This includes: the following measures: development of modern research methods and kinetic criteria for evaluating processes in the zone of frictional contact; creation of new antifriction composite alloys; methods of controlling the surface strength of materials during friction and wear [4,5]. Intensification of processes in the zone of frictional contact leads to an increase in thermal and mechanical load on the tribocoupler [6], with corresponding negative consequences [7,8].…”

The development and research of composite materials for heavily loaded tribo-couplings of car parts was based on the main provisions of the concept of structural and energetic adaptability of their materials during friction and wear. The presented data of experimental studies of the effect of ultrasonic treatment of materials on the nature of the change in the coefficient of friction depending on the value of the specific load at a constant sliding speed. Data were obtained that characterize the features of structural adaptation and self-organization during friction and wear of copper and lead alloys. The research was carried out using a universal tribometer according to the "finger-disc" end surface contact scheme in the medium of inactive petroleum jelly. The use of composite wear-resistant materials is proposed to increase the tribological efficiency of car parts, units and assemblies. Experimental studies and analysis of the obtained data were carried out on the basis of the developed parametric scheme for the study of tribocouples of samples and parts using the main provisions of system analysis.

“…1,2 It is recognized that some reinforcements/fillers in different polymer matrices have a marked effect on the mechanical and tribological properties. 3-6 Usage of different shapes and sizes of reinforcements in the composites are reported. 7,8 Carbon fibre reinforced and aramid fibre reinforced systems are currently getting due recognition which was earlier seen for the glass fibre reinforced ones.…”

In this study, the composites with incorporation betel nut powder at three levels (10, 18 and 25%) in Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) matrices having Kevlar Fibres (KF) and Molybdenum Disulphide (MoS2) nano particles in fixed amounts are looked into for their tribological characteristics. The effect of hardness, surface roughness and density was evaluated. FTIR and X-ray diffraction (XRD) studies have been carried out to identify the phases. The effects of load on the slide wear loss and coefficient of friction of the composites were determined using Pin on Disc set up. The wear test pertaining to the betel nut bearing (BNP) composites were compared with those of betel nut free ones i.e. PC/ABS/KF/MoS2. The results revealed that with increase in load, the wear loss increases. Further with increase in betel nut powder concentration from 10% to 25% there is a decrease in wear loss as well as coefficient of friction. The surface morphology of the worn surface were examined using Scanning Electron Microscopy (SEM) which revealed higher plastic deformation, debris formation and furrowing in BNP free systems compared to betel nut bearing ones.

“…Conventionally, these heterogeneous composites are consisting primarily of four classes of ingredients binder, fibers, fillers, and friction modifiers. The crucial contribution of fibers in enhancing physical, mechanical, and tribo‐performance (like wear stabilization/minimization and friction optimization) under the dynamic sets of operating variables is very well recognized 1–9. The role of fiber‐combinations based on inorganic‐organic such as aramid‐processed rock fiber (Lapinus™), polyacrylonitrile (PAN)‐basalt volcanic rock fiber, aramid‐basalt, cellulose‐lapinus, carbon‐lapinus, etc.…”

Hybrid composite friction material based on ternary combination of potassium titanate whiskers, alumino-silicate ceramic fibers, and aramid fibers were fabricated and evaluated for their physical, mechanical, and tribo-performance. The frictional response, friction-fade, friction-recovery, and wear properties have been characterized on a Krauss friction tester following ECE R-90 regulation. Optimally, the composite with hybrid reinforcement incorporations in the form of ceramic-whiskers, ceramicfiber, and aramid-fiber in the ratio of 13.75 : 13.75 : 2.5 has potentially been explored as a functionally feasible frictionmaterial for braking applications. The interdependence of fade, recovery, disc temperature rise, and wear characteristics is established via thematic correlation diagram.
