ARL-TR-8491 - Friction Characterization of Ultra-High-Molecular-Weight Polyethylene (UHMWPE) Composite Materials under Ambient Conditions | U.S. Army Research Laboratory
The friction properties for ultra-high-molecular-weight polyethylene (UHMWPE) composite materials are determined under ambient laboratory conditions. Two UHMWPE materials are selected, including solid-state extruded film DuPont Tensylon 30A and fiber system Dyneema HB 210, and one tooling material, Stretchlon 800 vacuum bagging film. The fabric?fabric interply friction and fabric?tooling friction is evaluated over a range of contact pressures, material orientations, and sliding velocities and then summarized. Static and dynamic coefficient of friction values were largely independent of both pressure and sliding velocity over the values tested. However, the friction response did depend on the material orientation angles of the reinforcement and the presence of a coating or matrix.
