The Dependence of Aftereffects and Contact of Rough Surfaces Composite – Metal from Orientation Factors of Dispersed Phase of Polymer Matrix
Abstract
Results of researches of influence orientation effects on the friction properties of carbon-plastics and wear mechanism of unidirectional carbon-plastics have been brought in a work. The optimal structure of carbon-plastics and fiber orientation layers in it relative to the surface friction and sliding direction have been provided. The influence of schemes reinforcing by fibrous carbon materials of polymer composites and schemes contacting of samples composites with the surface of metal counterface on the intensity of wear of friction pair and on the changing of microroughness parameters of metal surface have been researched. It has been shown that the topography of metal counterface surface changes in friction carbon plastics with oriented fibers, but the allocation of heights and curvatures of microroughness peaks of friction surface far removed from the Gaussian allocation and close to Rayleigh allocation.Keywords: carbon fibers, the intensity of wear, composite polymer material, reinforcing of layered composites schemes, roughness, isotropic surface, friction, spectral density, metal counterface, curvature of surface, aftereffect, effect of contact.
