“…Earlier friction materials were based on chrysotile asbestos fiber which phased out in last two decades because asbestos was proved as a carcinogen [1]. This has led to many developments in the last 20 years in friction material research whereby role of fibrous reinforcements is functionally expected to have a key bearing on the realistic performance of asbestos free friction materials [15][16][17][18][19].…”

In this article, multiwalled carbon nanotube (MWCNT) filled and lapinus‐Kevlar fiber reinforced friction composite material have been fabricated and characterized for their chemical, physico‐mechanical and tribological properties. The experimental results indicated that the density, hardness, impact energy, tensile, and flexural strengths decreases, whereas compressibility, void, and ash content of the friction composites increases with increase in MWCNT content. Further, Taguchi design of experiment technique was applied to study the tribological properties of the fabricated friction composites by taking four input parameter at‐a‐time such as composition, speed, distance and load, respectively, by using a pin on disc machine. An orthogonal array L16 has been applied to optimize the parameter settings to get performance output such as: coefficient of friction (COF) and specific wear rate (WR). The study reveals that the composition contributes mainly towards COF and WR with contribution ratio (CR) of 55.16 and 30.18% followed by speed with CR of 24.16 and 29.30%, respectively. Finally, confirmation experiment has been performed to verify the experimental results and is strongly correlated with the predicted results. POLYM.

“…The increasing fiber particle amount rolling between the contact layer of disc and brake composite would decrease the coefficient of friction. Other research reported that the value of coefficient of friction decreased with the increase in volume fraction of rice husk [27] and aramid fiber [28]. Figure 7 shows that the cantala fiber was also influential to the slope of the coefficient of friction as contact pressure function, in which the higher fiber percentage caused the slope to decrease.…”

Friction brake materials are made from a mixture of materials with different properties in order to meet the brake performance requirement. Friction brake material contains a reinforcement fiber that serves to maintain the integrity of the material when subjected to loading. Natural fiber has the potential to be used as a reinforcement material for friction material due to some of its superior characteristics. In this research, friction brake materials using cantala fibers were developed to investigate their frictional characteristics. The volume fraction of the cantala fibers in the specimens was varied from 0%, 4%, 8%, to 12% of the total composition of the friction brake material. The manufacturing of the specimen was initiated by mixing the ingredients, followed by cold pressing of the mixture, hot pressing of the preform, and finally post-curing of the specimens. The frictional characteristics of the specimens were evaluated using pin-on-disc tribometer. The result showed that the cantala fibers contributed to the decrease in the coefficient of friction. An increase in contact pressure caused the coefficient of friction to increase, while the increase in sliding speed caused a decrease in the coefficient of friction. The addition of cantala fiber into the composite could increase wear resistance and stabilize the coefficient of friction of the friction brake material.
