Abstract—The paper presents the results of a study on how the composition of a hybrid filler influences the strength and tribological characteristics of phenylone-based composites. The increase in the elastic modulus and yield stress for hybrid composites compared to phenylone was experimentally established as 40 and 45%, respectively; the values of the transverse deformation coefficient ranged from 0.18 to 0.23. The wear intensity of the developed composites is lower by an order of magnitude than that of the original phenylone, with a reduction in the friction coefficient by 50–60%. It is shown that in order to achieve the highest strength and tribotechnical characteristics, the optimal fiber content in the polymer matrix should be as follows: organic, 5 wt %; carbon fiber, 7 wt %. Under conditions of abrasive wear, the hybrid compositions exceed the original plastic by 1.2–1.7 times, reaching a minimum at a OF : CF ratio of 15 : 5 wt %. In general, reinforcement of phenylone with a hybrid mixture of carbon and organic fibers contributes to the development of abrasion-resistant hybrid composites under harsh operating conditions.
