Abstract
A process for the manufacture of a cured composite material, the process comprising the steps of blending together a liquid curable resin and a curing agent having a melting point greater than 100° C. to form a liquid blend of curable resin and curing agent, at least partially impregnating a structural fiber arrangement with the blended curable resin and curing agent to form a curable composite material, followed by curing the composite material by exposure to elevated temperature and at a pressure of no greater than 3 bar absolute to form a cured composite material.
