Publication number: 20110274907Abstract: Curative fibre components comprise one or more fibres for filaments of curative suitable to cure curable resins such as thermoset resin. In curative fibre components comprising a plurality of fibres of curative, the fibres can be commingled, such as twisting, to form a thread or yarn. Curative fibre components can be used to form a material in the form of a sheet, fabric, layer, textile or mat of woven or non-woven curative fibres. Curative fibre components can be used to produce composite materials such as fibre reinforced resinous composite materials. The curative fibre components can be commingled, including interwoven, stitched and layered with other fibres or fibrous materials, such as fibrous reinforcement, fibrous curable resin, fibrous thermoplastic, other non-reinforcing fibres to form composite materials, prepregs, preforms and articles.Type: ApplicationFiled: November 24, 2009Publication date: November 10, 2011Inventors: Mark Raymond Steele, Andrew Gibbs, Amy Grace Atinkson
