Composite polypropylene polymer materials that work in contact with raw cotton

Physicomechanical and tribotechnical properties of structural composite materials based on thermoplastic polymer organomineral ingredients operating under friction wear conditions during contact with pulp (raw cotton) have been investigated. The regularities changes in the physical, mechanical interaction raw cotton were determined, dependence their type content graphite, mineral fibrous fillers was studied. It has established that nature structure a certain effect physical polypropylene. At same time, fiber-filled compositions highest strength. also found when are introduced into materials, coefficient increases significantly, while rate decreases, except for plate (kaolin, talc), used, decrease is observed. introduction carbon-graphite composition leads to significant friction, temperature static electricity charge zone cotton. composites. provides high strength resistance material thermomechanical action. Effective work mass developed,
