Abstract: In this paper a matter of fact for successfully using of bisphenol A polyester-based composite material for filter housing in purification system of highly corrosive contaminated solutions is defined. The basic data about polyester resins and polymeric composite materials, way of producing neat resin and composite specimens and testing are presented. Neat resin specimens were exposed to the single influence of water solution of calcium hypochlorite, of sodium hydroxide, of sulphuric acid, of citric acid and liquid detergent for a period of 360 hours each, separately, and to the cumulative influence of all mentioned water solutions for 1440 hours. Tested mass up growth, hardness and impact strength showed that there is no negative influence on neat resin quality. Composite glass fibre reinforced/bisphenol A polyester resin-based rings were exposed to the influence of calcium hypochlorite water solution for1128 hours. Results of testing mass up growth and tensile strength of composite polymeric rings pointed out that these specimens have high resistance to mentioned purification agent. It is concluded that glass fibre reinforced/bisphenol A polyester resin-based composite material can be used for production of filter housing assigned to purification of highly corrosive contaminated solution.
