STUDY OF TRIBOLOGICAL PROPERTIES OF ORGANOPLASTIC BASED AROMATIC POLYAMIDES PHENYLONE C-1

Abstract

Tribological studies of the aromatic polyamide phenyl C-1 and organoplastic based on it, aramid fiber reinforced terlon in the amount of 15 mas % were carried out. It has been established that reinforcing C-1 phenylone with terlon fiber makes it possible to obtain antifriction material with a low coefficient of friction. In the entire studied load range, the maximum decrease in the coefficient of friction (by 54%) was characteristic of organoplastic, tested at a sliding speed of 1.5 m/s as compared with the binder. The nature of intensity of linear wear change of the materials was identical: at a sliding speed of 1 m/s, the indicator of C-1 phenylone samples and organoplastic increased throughout the load interval, under more stringent tests (u = 1.5 m/s, P = 0.8 MPa, as well as u = 2.0 m/s, P = 0.5-0.8 MPa), the polyamide binder and organoplastic catastrophically wore out and lost their performance. In general, the studied materials can be stably operated at sliding speeds of 1 and 1.5 MPa in the load interval 0.2-0.65 MPa.
