Law-Waste Technology for Production of Large Dimensions Articles from Glass Reinforced Plastics

Abstract

There was developed law-waste technology of small-scale production of large dimensions articles from glass reinforced plastics. This technology based on the use of close control equipment for simultaneous butch sputtering of all components of composite material, allows to mixing oligomers (resin) with curing agent and chopped glass fiber in the flow of air, outside the sputtering equipment, and in this case almost completely eliminates generation of industrial waste. Developed technology allows forming large dimensions articles continuously, without fear of turning of oligomers in polymer inside the equipment. There was discovering optimal structure of composite material. There was made choice of plastic binder and glass-fiber filler. The use as filler of chopped glass fiber with length of 50 mm ensures for composite material intended complex of physical and mechanical properties, and eliminates its anisotropy, which has place during the use of woven glass fabric, permeated by polymer compound. There was optimized technology of manufacturing of form-building equipment for production of standard and special modules from fiber-glass plastic.
