Study on tribological behavior of composite laminated material of monoaxial stretched PTFE film
By taking the chloroprene rubber plate as the backing material, with monoaxial stretched PTFE film as the surface layer, epoxy resin as binder, the samples of composite laminated material of monoaxial stretched PTFE film were formed on a hot press process. The tribological behavior of composites was tested on different test conditions by MMW 1A friction and wear tester. After testing, the worn surface and the transfer film was inspected and analyzed with KH 7700 3D video microscope. Results show that the materials with added PTFE film have better tribological properties than the basal materials and the friction coefficient dropped from 0.465 to 0.165. The load and sliding speed effect significantly on the tribological behavior of composite laminated material of monoaxial stretched PTFE film. The friction coefficient and wear rate of the composite laminated material is the lowest when the working condition is 125N, 20 rpm.
