Hybrid Phenolic Friction Composites Containing Kevlar® Pulp. Part II - Wear Surface Characteristics
The wear surfaces of control (without Kevlar®) and hybrid (with Kevlar®) phenolic composites were analyzed using a scanning electron microscope and energy dispersive X-rays to determine the influence of Kevlar® pulp on the wear surface morphologies at various sliding conditions. At a high sliding speed of 11.2 m s-1, the wear surface of a control glass fiber composite showed the formation of a nearly continuous and homogeneous film comprised of elements from the counterface and the composite itself. This film did not appear to form in a glass-Kevlar® hybrid composite at a similar operating speed. At 11.2 m s-1, a control steel fiber composite was found to wear due to a predominantly abrasive mechanism, while this mechanism was diminished in a steel-Kevlar® hybrid composite.
