Friction of Self-Lubricating Polymer Composites Reinforced by Heat-Resistant Fabrics

摘要

The effect of a phenolformaldehyde binder and the nature of reinforcing fibers, i.e., polyoxadiazol and carbon fabrics, on the specific features of the friction of polymer composite materials (PCMs) and the formation of their self-lubricating properties is shown. The friction of these PCMs is experimentally studied and an analysis of specific features of this process is carried out based on the first formulated general principle of the structure of a friction surface of these PCMs that implies the rigid fixation of fibers in the structure of a fabric. The effect of properties of the fibers and binder on this process is established.
