High-Performance Polymer Fibres

Report 107 High Performance Polymer Fibres, P.R. Lewis, The Open University. [Pg.128]

Various types of fibres could be used in making filter fabrics they include glass fibres, synthehc fibres, ceUulosic fibres (eg, natural wood pulp fibres, viscose fibres, and Lyo-ceU fibres), wool fibres, metal fibres, ceramic fibres, high-performance polymer fibres (eg, inherenfly fire-resistant fibres, chemical resistance fibres, high-strength, and high-modulus fibres), microfibers, and nanofibers. [Pg.275]

Glass fibres, metal fibres, ceramic fibres, and high-performance polymer fibres are able to meet special requirements in special applications, such as filtration in high-stress, high-temperature, corrosive, or chemical hazardous environments. Filters containing fine glass fibres or glass microfibers are resistant to chemical attack but relatively brittle when pleated, and produce undesirable yield losses. [Pg.276]

Many high-performance polymer fibres are used in filter media to meet various specific requirements in diverse filtration applications. Filters made from fluoropol-ymer (Polytetrafluoroethylene (PTFE), Polyvinylidene fluoride (PVDF), and Per-fluoroalkoxy alkane (PFA)) fibres, and membranes have inherent, chemical-resistant, and flame-retardant properties, and they are widely employed to filter aggressive chemicals and acids in the manufacture of wafers and microchips in the microelectronics industry. Ethylene ChloroTriFluoroEthylene (E-CTFE) melt blown fabrics have a unique ability to coalesce difficult liquids and can withstand the piranha effect in filtering ozone enriched ultrapure water. Polyphenylene sulfide (PPS) fibres are also chemical resistant, stand high temperature, and are suitable for making baghouse filters. Eilter media made from other high-performance polymer fibres, such as polyamide-imide, polyetherimide (PEI), Polyimide P84 fibre,polyetheretherke-tone, and liquid crystal polymers also appear in the filtration and separation market. [Pg.278]

Polyether ether ketone (PEEK) and Polyether sulphone (PES) belong to the most recent developments in the field of technical high-performance polymers. Both possess very good thermal and mechanical properties, which can be further improved by reinforcing fibres. Their application is mainly in aircraft and space vehicles. [Pg.18]

This is a thermoplastic material, the correct name for which is poly-etheretherketone. PEEK is also regarded as a high-performing polymer, offering excellent chemical resistance, very low moisture absorption and good wear, abrasion and electrical resistance. It can be used continuously to 250°C in hot water and steam without permanent loss in physical properties. It is used to replace metal parts in the aerospace, automotive, oil and gas industries and is available reinforced with glass and carbon fibre. [Pg.227]

While self-reinforced polymer composites based on PE and PP have received most attention in recent years, there is also great scope for the use of PET in self-reinforced polymer composites, since many high performance PET fibres are commercially available. Although not comparable to commercial UHMWPE fibres in terms of mechanical properties, the mass productimi of PET fibres and... [Pg.45]

Over the IS years since the original Raman deformation studies upon polydiacetylene single crystals, the technique has been developed and refined to involve the study of a wide range of different high-performance polymers and other materials. These have included rigid-rod polymer fibres [19-21], carbon fibres [22-24] and ceramic fibres [2S-27]. This present chapter will concentrate upon recent research concerning the use of Raman spectroscopy to follow the deformation of aramid fibres and gel-spun polyethylene fibres and the possibility of the extension of the technique to isotropic polymers, and also the important and developing application of the method to the study of the deformation of fibres within composites. [Pg.206]
