Abstract

An antifriction organoplastic based on epoxy binder and combined fabric filler including polytetrafluoroethylene and polyimide fibers was investigated. Data on its basic physical properties, physico-mechanical properties under uniaxial tension were obtained. The stress-strain curves were analyzed, the temperature dependences of the modulus of elasticity, strength and elongation at tension were established. Antifrictional organoplastic was a polymer composite material with 0,25–0,30 mm thickness and 1,55 g/cm3 density, has resistance to water and aviation petroleum products. It was shown that in the investigated temperature range from -40 to +60°С the organoplastic was characterized by strength of 30–110 MPa, elastic modulus of 0,7–4,5 GPa and deformations of 3–22%. According to the results of the research, antifriction organoplastics can be successfully used as a coating of a given size and shape for the modification of friction surfaces without significant weight gain and changes in t
