The effects of resin rate (wt-%) on different temperature performance of newly designed friction composites for automobile brake lining applications

“…In a different study, researchers reported that as the resin ratio increased, the resin particles filled the empty voids during the hot-pressing process, increasing the contact area between the particles and causing a reduction in porosity. They reported that reduced porosity resulted in an increase in density and hardness [34]. The high surface hardness of the resin indicated that it had transformed into a harder matrix after curing due to the larger average molecular size.…”

Characterization of Areva javanica fiber – A possible replacement for synthetic acrylic fiber in the disc brake pad

“…For comparison purpose, a commercially successful Original Equipment Manufacturer (O.E.M) brake pad purchased from the market was also taken for testing. The density of the friction material was found by the water displacement method based on Archimedes principle [41]. Hardness was calculated in 'S' Scale using a Rockwell testing machine with a major load of 100 kg-f with a ball indentor of size 3.125 mm.…”

Influence of Binder on Thermomechanical and Tribological Performance in Brake Pad

“…J Bijwe et al reported that the trends in performance properties of brake pad materials were not changing uniformly with increasing content of binder [8]. The influence of altering the molecular weight of Alkylbenzene modified resin on a disc brake pad was investigated and found that the medium molecular weight reduced the fluctuations of CoF [12]. The research works were commonly conducted on a different type of resins, modified resins with fillers.…”

“…Tsang et al [11] emphasized that the tests conducted using small sample testing machine have not identified as promising test methods for screening automotive brake pads. This was due to the large variability in friction results observed in the small size testing machines [12]. Very few works reported on the influence of the binder quantity and evaluation in more rigorous conditions using an IBD.…”
