Carpet Knit - warp knitting technology sets new standards in carpet finishing (German)

It is shown that a warp-knitted carpet can be stabilized by coating with modified polypropylene or with water glass. They are particularly advantageous for subsequent carpet recyling and guarantee good product characteristics. Additives can be used to impart flame resistance and antistatic properties. These need not be used when water gla..

Fiber, matrix, and interface properties

This volume features the latest information on the role of fibres, matrices, and their interface/interphase in composite performance. Thirteen papers are presented covering innovative approaches to interfacial test methods in composite materials development. Topics included are: Dynamic mechanical evaluation techniques for interfacial pro..

Mechanical characterisation of glass- and carbon-fibre-reinforced composites made with non-crimp fabrics

The labour-intensive requirements of manufacturing unidirectional prepreg tape laminates is driving industry to examine alternative processing routes that combine all the attributes of unidirectional prepreg tapes, but with reduced ocst. One such technique that offers automated high-volume production with the potential for near-net-shape ..

Aramid fibre-reinforced concrete from Japan

Six fibre and general construction material companies in Japan have embarked on joint work which aims at confirming the performance of concrete reinforced with aramid fibre. Teijin Ltd and Tokyu Construction are two of the companies working to produce the material which is seen as a next generation structural material to replace ferro-con..

Microstructure and mechanical properties of HI-Nicalon/BN/α-silicon-nitride ceramic-matrix composites

Unidirectional ceramic-matrix composites consisting of BN-coated Hi-Nicalon (SiC) fibre in a silicon nitride matrix were fabricated by a slurry-impregnation/hot-pressing route. the microstructures of the composites were investigated by scanning and transmission electron microscopes and atomic force microscopy, while the mechanical paramet..

High tenacity polyethylene for composites

A high tenacity polyethylene fibre which absorbs vibrations well at low temperatures has been developed by Toyo Boseki KK. The new product has a high impact resistance suggesting its use as a reinforcement in composites designed for low temperature applications, 200 degrees C or below. The company suggests that the fibre could be used as ..

Effect of notch and test conditions on the fatigue of a glass-fibre-reinforced polypropylene composite

This paper is concerned with fatigue studies on polypropylene/glass-fibre thermoplastic composites produced from a bidirectional woven cloth of commingled E-glass and polypropylene fibres (the latter becoming the matrix after the application of heat and pressure). This composite was manufactured with a fibre volume fraction of 0.338. The ..

Noise Reduction Systems for Textile Equipment.

Problems arising from high noise levels during manufacturing include risks to employee hearing, workers compensation liability, meeting health and safety regulations, loss of productivity, and increased insurance premiums. Effective noise reduction analyzes such elements as source, path, and receiver. Noise reduction can occur at the sour..

Preparation and Characterization of Crosslinked Porous Silk Fibroin Gel.

Researchers investigated the preparation and characterization of crosslinked porous silk fibroin gel (CPEG) to develop new biomedical materials. They used ethylene glycol diglycidyl ether (EGDE) as a crosslinking agent and prepared the CPFG by freezing at -50 to -5 degrees centigrade and thawing a homogeneous fibroin solution containing E..

Textiles within the Automobile.

Part one of a two part series of articles focuses on automotive textiles. As the annual convention of the Wirkerei und Strickerei Fachleute (hosiery and knitting experts), Heiner Finke of Deutsche Bobinet GmbH discussed the use of such textiles as warp knit fabrics in automobiles. Warp knit fabrics are currently used for headliners and su..
