In this paper, the possibility of creating new structural organoplastics based on aromatic polyamide of phenylone, fiberreinforced sulfone-T, is considered. Analysis of the results of physical and mechanical properties showed that, on the one hand, the introduction of an organic fiber into the polymer matrix leads to an increase in hardness, modulus of elasticity, and Poisson’s ratio of 1.7; 1.9 and 1.3 times, respectively, on the other hand, there is an insignificant increase in the relative strain and yield stress at compression in the range of 10%, which is due to the presence of micropores formed at the polymer-fiber interface in the structure of organoplastics with the introduction of fiber filler over 15 wt.%. An increase in wear resistance of 1.6 times was observed, while a reduction in the coefficient of friction by 60%, compared with pure phenylone. Positive results of the research made it possible to switch to industrial ones – replacement of roller bearings of pins on sliding bearings made of polymeric composite material, which led to an increase of 3-4 times the working life as compared to serial ones.

Now there are a number of important scientific and technical problems of producing fibers with a specified set of properties and high quality indicators, process optimization and efficient processing of their applications. In this context, the aim of this work was the possibility of creating new self-reinforced polymer composites based on ased on aromatic polyamide phenylone reinforced with organic fibers.The properties of self-reinforced composites based on aromatic phenylone are presented. It is shown that the optimum fiber content are 5-10 wt.% in the polymer matrix.

The polymeric composites on the basis of a thermosetting matrix, chaotically reinforced chemical fibers with a broad band and high level of operating performances have been developed. The optimum geometrical parameters of a fibrous filler, degree of filling of a matrix at a different dispersibility of a filler ensuring high technological effectiveness and degree of strengthening have been defined. The thermodynamic conditions of obtaining strong adhesive connection of a matrix with a filler have been explored during receiving polymeric composites.
