Comparative study of Abaca fiber and Kevlar fibers based brake friction composites

Self Cite

This research article has developed a novel composite material using natural fiber and PAN fiber. The study aims to remove harmful materials from the composites on the market these days. Asbestos and aramid fiber has good properties and is used in those composites where good mechanical properties are needed. However, using these materials causes many environmental issues and harms humans and other animals. There are very rare studies of PAN and natural fiber based hybrid composites. So Grewia optiva, which has good mechanical properties, and PAN fiber, which has good tribological properties, has been used to develop composites. The percentages of both materials were taken (4-16 wt%) with other ingredients such as phenolic resin, G. optiva fiber, PAN fiber/Kevlar, and lapinus ceramic, potassium barium, titan, mica, and ceramic. The developed composites have shown physical, mechanical, and tribological properties.

“…Natural fiber has good mechanical, physical, and chemical properties. [16,17] Kevlar has now replaced asbestos and has excellent braking properties, but research has shown its negative impact. The use of asbestos started by keeping its advantage of excellent braking properties, although further research has found that it leads to various kinds of cancer and causes serious lung disease.…”

Recently, natural fibers have shown their importance in certain kinds of composites. The trending composites are mostly made using organic fiber due to their good eco-friendly nature, their easy availability, and reasonable cost. Natural fibers are replacing synthetic fibers in every field. In this research article, natural fibers like bamboo fiber and PAN fiber have been utilized to develop a new kind of hybrid composite and compared to aramid fiber reinforcement. The brake pads were fabricated with the inclusion of various percentages of mass of bamboo fibers and PAN fiber (3%-12%) with an equal ratio of Aramid fiber (3%-6%) in the hydraulic hind brake molding device. The chemical, mechanical, physical, tribological, and thermal properties were evaluated.

Synchronously improved ozone aging resistance and tribological performance of self‐lubricating fabric composites via 2‐mercaptobenzimidazole

et al. 2022

Self-lubricating fabric composite can be used as liner material in plain bearings of aeronautical aircraft. The concentration of ozone in the cruising altitude of aircraft is relatively high and the oxidation of ozone will reduce the tribological property and service life of the self-lubricating fabric composites. In present work, 2-mercaptobenzimidazole (MB) was chosen and filled into selflubricating fabric composites to improve their ozone aging resistance and wear resistance performance. Characterizations demonstrated that the optimum filling ratio of MB was 4 wt%. The glass transition temperature of resin and decomposition temperature of the composite filled with 4 wt% MB were 96.3 s and 475 C, which increased by 12.6% and 6.7% compared with that of resin and composites without filling MB, respectively. The tribological performance and ozone aging resistance performance of MB reinforced self-lubricating fabric composites acquired obviously enhancement. The wear rate of MB reinforced self-lubricating fabric composites after different ozone aging time decreased by 42.4%-61.8% compared with that of composites without filling MB owing to that the addition of MB improved the oxidation resistance and thermal stability of self-lubricating composites.
