UP-GF (FRP) PIPES, MOLDED PARTS AND CONNECTIONS Pipes made of glass-fibre reinforced polyester resins (UP-GF) with and without thermoplastic lining according to DIN 16 965 - section 2 / section  4  - pipe type B and D

Glass-fibre reinforced plastic, abbreviated as GFRP (in German GFK = Glasfaserverstärkter Kunststoff), also referred to as duroplast, consists of plastic resin and a fibrous reinforcing material. Glass fibres impregnated with an unsaturated polyester resin (UP) or with a vinyl ester resin from the duroplast group, serve as reinforcement material. Glass-fibre reinforced plastic shows an excellent corrosion stability and high chemical resistance, even in aggressive environments, which makes it an appropriate material for pipe systems and tanks in the chemical industry and process engineering.

GFRP - Glass- fibre reinforced plastic

Glass-fibre reinforced plastic, abbreviated as GFRP (in German GFK = Glasfaserverstärkter Kunststoff), also referred to as duroplast, consists of plastic resin and a fibrous reinforcing material. Glass fibres impregnated with an unsaturated polyester resin (UP) or with a vinyl ester resin from the duroplast group, serve as reinforcement material. In Germany, the vinyl ester resin is identified officially as phenactylate resin and is based for the sorts e.g. Derakane 411-350 or Distrotone VE 100 on  bisphenol A and for the sorts e.g. Derakane 470-300 or DION 9400 on novolac resin. Before processing, these resins are viscous solutions of so-called unsaturated polyesters, which are dissolved in copolymeriazable monomers (styrene). The final product GFRP consists of this plastic material and glass fibres. Good impregnation of the glass fibres with resin is of decisive importance for the product. Before impragnating the glasses accordingly by hand or automatically, radicals (peroxides) have to be added to the liquid resins, in order to imitate the reaction and to transfer the resin from the liquid state to a cross-linked state. During linking, no other fission products are produced. The solvent styrene will partly be released during processing. The process time takes 15 to 45 minutes and can be accelerated or slowed down by means of accelerators and/or inhibitors. With the three components (hardener, accelerator and inhibitor), the recipes are mixed individually according to the weather conditions and the necessary processing time and adapted to the specific processing performed. According to recipe starts within approximately 30 to 120 minutes an exothermic hardening reaction and warmth is released. This reaction brings about hardening of the unsaturated polyester resins under formation of cross-linked substances by means of copolymerization cured through radicals. With the styrene,  the polyester molecules are forming network structures. A product manufactured like this can not be liquified by heating and not be dissolved by solvents (duroplast).

The processed glasses and their percentage depend on the required mechanical properties. After the hardening process, the product can be utilized according to the requirements. For a certain time, a  postpolymerization takes place, however this process is not measurable or detectable at all. For disposa, the finished product can be burned (glass, ash) or stored, as a chemical reaction with any other materials is impossible. Typical applications for glass fibre reinforced plastic are: • Vehicle construction • Aviation • Ship building • Bridge construction • GFRP sections for "steel construction“ • GFRP rebars for concrete construction • Hall doors • Wind-driven power stations • Model making • Pipeline construction • Tank construction for the chemical industry • Apparatus engineering • Special components for chemically stressed parts • Insulation of electroconductive parts • Water slide complexes • Bathtubs, shower trays, washbasins • Jointless shower cabinets for use in mobile space units and sanitary containers • Tuning bumpers • Motorcycle fairings (tuning for weight reduction) • Interior covers (e.g. door panels in vehicles) • Head protection (e.g. firefighter helmets and motorsport helmets) • Facade construction • Tank construction (e.g. heating oil tanks and heat accumulators) • Silo construction (storage of animal feed and grain)
