Abstract
This paper focuses on tribotechnical and physical-mechanical properties of the BSP-7 copolymer and organoplastics based on it with 10 ÷ 40 mass % of polyheteroarylene vniivlon fiber. It demonstrates that the reinforcement of copolymer with organic fiber improves its abrasive wear resistance by 64,2 % at a maximum filler content of 30 mass %. Proposed organoplastics based on the BSP-7 copolymer with effective content of 30 mass % of the filler can be recommended as a tribotechnical material for the manufacturing of the parts that work in the conditions of abrasive wear.
Highlights
Abrasive wear of materials is one of the most widespread in practice types of wear to which the parts of agricultural, road-building, mining, transport machines, friction units of metallurgical equipment, еtс are exposed
The development of new polymer composite materials (PCM) capable of operating at machine friction units and mechanisms of variouspurposeunder specified operating conditions taking into account the nature of the impact of abrasive particles on the workpiece is an effective solution to the problem of increase in wear resistance and reliability of the parts [1 - 3]
It is known that as the fiber content increases the strength of the filled polymer increases to a certain level, after which there is a slowdown in the growth of indicators, or even their decline
Summary
Abrasive wear of materials is one of the most widespread in practice types of wear to which the parts of agricultural, road-building, mining, transport machines, friction units of metallurgical equipment, еtс are exposed. The intensity of abrasive wear is influenced by the nature of abrasive particles, aggressiveness of the environment, physical-mechanical properties of wear surfaces, shock interaction, temperature and other factors. The development of new polymer composite materials (PCM) capable of operating at machine friction units and mechanisms of variouspurposeunder specified operating conditions taking into account the nature of the impact of abrasive particles on the workpiece is an effective solution to the problem of increase in wear resistance and reliability of the parts [1 - 3]
