Abstract
Experimental studies have been carried out to study the effect of various fillers on the physicomechanical and tribotechnical properties of the compositions, and the optimal filler contents have been established, which ensure the best properties of polyethylene, polypropylene, polystyrol and polyamide structural composite materials. The principle of design of shock-resistant, antifriction and antifriction-wear-resistant polyethylene, polypropylene, polystyrol and polyamide structural composite materials is proposed. Highly efficient structural composite materials for functional purposes have been developed on the basis of thermoplastic polymers and fillers of various structures and natures, which have sufficiently high strength and tribotechnical characteristics and have found application in the working bodies of cotton machines and mechanisms of the cotton processing industry operating under conditions of friction and wear.
Highlights
Structural composite materials are widely used, the creation of which is due to the need for new materials in various branches of mechanical engineering, including the cotton ginning industry
For the manufacture of parts of rubbing pairs of working bodies of machines and mechanisms, it is required to develop new structural composite polymeric materials for functional purposes, intended for operation under friction conditions, when they interact with raw cotton
For the manufacture of parts of rubbing pairs of working bodies of machines and mechanisms, it is required to develop new composite polymeric materials for functional purposes, designed to work under friction conditions when they interact with raw cotton
Summary
For the manufacture of parts of rubbing pairs of working bodies of machines and mechanisms, it is required to develop new structural composite polymeric materials for functional purposes, intended for operation under friction conditions, when they interact with raw cotton. This determined the basic requirements for them. Such materials should have high impact resistance, low coefficient of friction, minimal wear when rubbing with pulp (raw cotton). It is advisable to develop scientific principles that are necessary, as initial data, when creating shock-resistant (UP), antifriction (A) and antifriction-wear-resistant (AI) composite polymer materials (CPM)
