The sliding wear rate and frictional coefficient of epoxy/rubber or epoxy/rubber/aluminium oxide composites were measured against themselves as a wear rate. The observed wear rate-sliding velocity data appear to be explicable by a recently proposed fatigue-shear model based on damage accumulation physics. The proposed equation seems to explain both dry and wet friction (water lubricant) environments. The microstructural features of a worn surface were examined using a scanning electron microscope (SEM) and related to the measured tribological data.

The dry erosion behavior of epoxylwaste rubber composites has been investigated as a function of rubber content, air pressure (particle velocity), and impact angle. Morphological aspects have also been examined.The experimental data have been expkined by means of an analytic equation derived from the crack propagation physics.

ABSTRACT

The friction and wear behavior of silicone-impregnated fiber-reinforced thermoplastics has been investigated as a function of normal load in air, water, and oil lubricants using a two-body abrasion tester. The measured tribological data have been phenomenologically explained by a wearlfriction equation derived from the concepts of crack propagation and wear failure mode.
