“…Determination of hydraulic burst pressure of glass fiber/bisphenol A polyester system cylinder specimen before and after an immersion in aqueous solution of calcium hypochlorite consists of testing of a burst pressure in a short period of time. The burst pressure is determined under the influence of internal hydraulic pressure of water and the air was around a cylinder specimen (version water-air) [22].…”

Practical and realistic approach for a successful use of filament wound filter housing based on bisphenol A polyester resin for purification of highly corrosive contaminated solutions is presented in this paper. Filament winding technology and basic terms about polyester and polymeric composite materials are described. Data about modes of producing neat (no reinforced) bisphenol A polyester resin specimens and composite material specimen, based on mentioned resin and glass fiber, are presented. Neat resin specimens were exposed to the single influence of aqueous 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 aqueous solutions for in overall period of 1440 hours. Tested properties of these specimens (mass change, hardness and impact resistance) showed that there is no negative influence on neat bisphenol A polyester resin quality. Filament wound composite reinforced glass fiber/bisphenol A polyester resin-based rings and cylinders were exposed to the influence of calcium hypochlorite aqueous solution for 1128 hours. Results of testing mass change, tensile breaking force and tensile strength of composite reinforced rings and hydraulic burst pressure of composite reinforced cylinders indicated that these specimens have high resistance to mentioned purification agent. It is concluded that the filter housing for purification of highly corrosive contaminated solutions can be produced by filament winding technology using bisphenol A polyester resin and glass fiber.

“…Of all hydraulic properties, internal hydraulic burst pressure is chosen for characterization of filament wound composite one fiber tubes and hybrid tubes in this investigation. Mentioned hydraulic characteristic is determined in so called water-air test i.e., water under pressure is inside the tube and air is around the tube [11].…”

In this paper volumetric, mechanical and hydraulic characteristics of filament wound composite one fiber tubes and hybrid tubes are presented. Composite hybrid materials, produced by filament winding technology, are categorized according to different ways of classification of hybrid materials. Four fibrous reinforcement agents (glass G600, polyamide aromatic K49, carbon T300 and carbon T800) and two impregnation agent systems (epoxy 0164 and epoxy L20) are used for manufacturing of filament wound tubes. Density, tensile strength, specific tensile strength, hydraulic burst pressure and specific hydraulic burst pressure of two filament wound glass fiber/epoxy resins tubes (as starting materials) and of twelve filament wound hybrid tubes are investigated. Four highest values of tensile strength and hydraulic burst pressure are of the next schedule: hybrid tubes mark G600-T800/L20 (the highest), hybrid tubes mark G600-T800/0164, hybrid tubes mark G600-T300/L20 and hybrid tubes mark G600-K49/L20. Also, a row of four highest specific tensile strength and highest specific hydraulic burst pressure begins with hybrid tubes mark G600-T800/L20, but the schedule of the next three tubes is different due to density of aramide composite materials (hybrid tubes mark G600-K49/L20, hybrid tubes mark G600-T800/0164 and hybrid tubes mark G600-K49/0164). All filament wound tubes (single fiber tubes and hybrid tubes) with epoxy L20 have a slightly lower density value but higher values of tensile strength, specific tensile strength, hydraulic burst pressure and specific hydraulic burst pressure than appropriate tubes impregnated with epoxy 0164. Obtained results in this testing indicate and emphasize the importance of advanced reinforcing agents (aramide roving and carbon fibers), of impregnating agents (epoxy resin systems) and of the density of hybrid tubes, especially with aramide roving.
