Composite Materials with Enhanced Abrasion Resistance and Certain Functional Characteristics Based on Thermoplastics

The structure and composite materials formation technology with specified indicators of functional characteristics based on organic and inorganic binders are investigated. Composite materials with increased resistance and wear, water resistance, based on thermomechanically combined polyamide-polyethylene (PA6-PET) mixtures have been developed. The dependence of the composite material characteristics on the phase structure formed during the thermomechanical interaction of the mixture components is established. The resistance to cracking under load and the abrasion resistance of composites based on mixtures of "thermoplastics-thermoplastics", thermoplastics modified with highly dispersed fillers are investigated. It is established that the introduction of nanometer dispersion of active fillers into the mixture increases the strength and tribotechnical characteristics of composite materials due to the formation of physical crosslinking nodes. Modification of the Ultrafine diamond graphite (UFDG) increases the wear resistance of high-pressure polyethylene (HPPE) by 3 times, low-pressure polyethylene (LPPE) by 2 times, polypropylene (PP) by 3 times when rubbing along a web with fine abrasive grain. Composite materials with specified functional characteristics have been developed for the manufacture of new-generation gimbals gear parts
