The friction and wear of monolithic polyamide 66 (PA66) and a PA66 composite reinforced with short glass fibers were examined using a block-on-ring friction tester with particular focus on the effect of weight average molar mass (Mw) of PA66. The amount of glass fibers in the composite and the molecular weight strongly affected the friction level and wear rate because it altered the shear strength...
This study examined the friction and wear of brake friction materials containing two different abrasives: zircon and quartz. Commercial grade abrasives with two different sizes (fine and coarse) were compared in terms of the effects of the size, shape, and toughness of the abrasive particles on the friction and wear of the friction material and counter discs. The results showed that the morphology...
Wear of the brake friction materials with straight phenolic resin, silicon modified phenolic resin, or boron–phosphorous (B–P) modified phenolic resin was investigated. A simple formulation was used to produce friction material specimens and wear tests were carried out using a Krauss type friction tester. Friction stability and wear rate of the three friction materials were compared as a function...
