Frictional Response of Reinforced Polymers under Quasistatic and Fast-Transient Dry Contact Conditions

Reinforced polymers have recently gained interest because of their high stiffness associated with the classical features and cost-effectiveness polymers. A further characteristic, suitable for several applications, is possibility to provide frictional wear resistance. The response commercially available reinforced materials was here investigated in a wide range contact boundary conditions. Experimental tests were performed on different test benches, investigate material under either quasistatic or fast-dynamic solicitations. While carbon-fiber-reinforced exhibits stable but low friction coefficient, glass-fiber-reinforced leads combination wear. PPS material, 40% (wt) glass-reinforced polymer, sliding against Ti6Al4V titanium alloy, provided static coefficients (>0.4). same pair then tested endurance solicitations, highlighting resistance
