Reinforced and filled polymeric composite materials (CMs) are gaining the interest of scientists, researchers and industrialists all over the world. Polymeric composites being lighter and cheaper than the metal-based composites are seen as a scope for advancement in the ever-evolving field of materials science. Moreover, polymeric CMs have widely spread in different branches of industry, especially water transport. Therefore, it was substantiated in the work that an important operational property of vehicles, which determines their durability and service life, is wear resistance (determined by wear intensity) under the action of hydroabrasive. In this regard, the use of polymeric composites, including epoxy and protective coatings, based on them, is relevant for the part restoration. It has been shown that the developed CM has high potential for improving vehicle parts. The epoxy composite matrix modified by 4-aminobenzoic acid was prepared with loading of active dispersed particles in the form of a synthesized titanium-aluminum powder mixture (Ti (70 %) + Al3Ti (15 %) + Ti3AlC2 (15 %)), powder mixture (TiH2 (65 %), FeSiMn (30 %), B4C (5 %)), and discrete carbon fibers FC-H. The optimum content of the fillers has been found (pts. wt.): 0.4-0.6 : 0.04-0.06 : 55-65. The CM is characterized by lower wear intensity under the conditions of hydroabrasive, compared to known world analogues. This indicates the feasibility of using the developed material to increase hydroabrasive wear resistance of water transport parts, which operate under the action of mechanical loads and elevated temperatures. The broad applicability of the developed material as a functional protective coating has been confirmed. The application of the developed protective coating to the transport allows to reduce the wear intensity from the action of hydroabrasive parts by 2.43.6 times, and the rate of restoring defective parts by 2.0-2.5 times.
