Product Name: Carbon Fibre Tubes

Product Description

Processes There are a variety of manufacturing processes applicable to the production of composite tubes. The choice of process is influenced by the properties required, quantity, costs, etc. Pre-Preg Rolling Layers of material are rolled around a mandrel, by hand or machine, prior to consolidation and cure. When hard the outside diameter can be machined if required. Ideal for smaller quantities and smaller tubes where increased material costs are less significant. Pultrusion A continuous process in which fibres in the form of rovings, mat or fabric are impregnated with resin and pulled through a heated die of the required shape, moulding both the inside and outside diameters. Uses raw materials in their most basic and lowest cost form, however large quantities need to be produced to justify the high tooling and set-up costs Limited choice of fibre angle. Filament Winding After impregnating with resin the fibre is wound onto a mandrel at the angle required to produce the mechanical properties. Conventionally tubes produced in this way have a moulded Inside diameter, the outside diameter can be machined if required, after curing. Technology developed by Performance Composites Ltd. allows us to mould the OUTSIDE diameter rather than the inside diameter, this also allows shallow fibre angles (typically down to ± 5°.), and provides better consolidation/laminate quality. This process is particularly suited to medium to large batch quantities or larger 'one offs'
