The Manufacture and Evaluation of Braided Fibre Reinforced Composite Tubes,
Abstract
Tubular structural elements have been successfully produced from composite materials by a variety of processes, such as pultrusion, wrapped cloth, filament winding, tape winding and wrapped prepregs, and the qualities of the tubes so obtained are fairly well established. Pultrusion, although best suited for production requirements, can only really produce longitudinally unidirectional fibre reinforcements. If torsional stiffness is required then some other process must be used. Filament winding is an obvious choice but the size of the winding apparatus may limit the product. Wrapped cloth and pre-preg can be beneficial but are not suited to continuous production. Torsional stiffening fibres can, however, be laid down in a tubular structure by braiding at a point in a process, and the technique would be suitable for use in production. A braiding head was modified to produce multi-layered braided reinforced tubes and the effect of manufacturing parameters on the torsional stiffness of the products investigated. (MM)
