Graphical Assessment of the Linear Contact Steel on Composite Material at High Temperature and Pressure: A Recent Study

Based on comprehensive experimental tests, a study for the evolution of wear for a certain duration, as well as for certain loads and contact temperatures. In this article we have tried to present a graphical assessment of the dry linear contact for composite materials reinforced with glass fibers as well as of the influence of the sliding speed, load and friction coefficient. Perpendicular loads, the contact temperature and the wear of the metal surface were recorded .The wear volume was calculated using the Archard relationship. Using the Archard relationship, the width of trace can be calculated in 3 locations. Numerous experimental trials were performed in connection to the wear of the metal surface, the contact temperature and the value of the friction coefficient. The friction coefficient for the composite material and for the C 120 steel samples is higher than the one obtained at the surface of the steel samples. This is due to the differences in hardness between the two types of steel. A connection between the evolution of the wear process and the dependency on the contact temperature and friction coefficient can be observed.
