The purpose of this programme was to develop pre-impregnated13; -epoxy rovings which are suitable for filament wound13; pressure vessels. Use of a preimpregnated winding material is necessary in the fabrication of aerospace structural components, for which predictable strength properties are important.properties such as resin content which adversely affect the of filament wound components, can be easily cona13; preimpregnated winding material is used in the Specially in winding large components, involving ble fabrication time, use ot wet winding technique resulting variation of the mechanical properties of the component is due to the low Viscosity resin systems normally employed wet winding. which are prone to set at ambient temperatures, resulting in variation of mechanical properties throughtout the wall thickness of the component
