Fibre ropes and composite materials containing fibre ropes

A rope or yarn 4 comprises a plurality of fibre strands 1. Each strand is formed by twisting a tow 2, the tow comprising a plurality of fibres 1 of a non-polymeric, non-metallic and high modulus (Youngs of greater than 20 GPa) material, such as carbon, boron, glass, ceramic or quartz fibre. The tow is twisted with a first twist density to form each of the fibre strands 3, and the strands are twisted with a second twist density to form the rope 4. Each fibre strand has a helical angle with respect to the elongate axis of the fibre rope of at least about 15 degrees. The first and second twists may be executed simultaneously, each have a density of more than 25 turns per meter, be helical and in opposite directions to each other. A single rope may be combined with a matrix material to form a rod. Ropes may be knitted or woven into a fabric and may be used to from a composite material. Resin for a composite may be added after formation of the rope. For use in aircraft or vehicles.

Crimped hollow fibers for fluid separations, bundles containing the hollow fibers, and apparatus and process for separating fluids

Hollow, semi-permeable fibers which are intended for use in fluid separations have crimps with amplitudes up to 50% of the external diameter of the fiber and an average crimp period of less than 5 cms. The fibers are sufficiently rigid to retain its crimp form during fluid separation. Preferred fibers have an outside diameter of 150-800 microns, a wall thickness of 50-200 microns and a crimp amplitude of 15-250 microns. The tensile modulus is at least 40 kg/mm<2>. The relatively low amplitude crimps enable good fluid dispersion through a bundle comprising substantially parallelly-oriented hollow fibers such that shell-side (i.e., the exterior sides of the hollow fibers) feed of the fluid mixture to be treated can be attractive, even when the flow of the feed is predominantly axial to the hollow fibers. Shell-side feed of the fluid mixture to be treated is often particularly advantageous since the fluid mixture can frequently be recovered from the fluid separation with a relatively low pressure ...
