Patent ID: 7063759

Claim:
A method for curing a composite material, comprising: providing an oven, the oven comprising: an inner wall defining an inner chamber; an outer wall, the outer wall and the inner wall defining an outer chamber therebetween; a hot air distribution manifold disposed within the inner chamber; and a cold air distribution manifold disposed within the outer chamber; disposing the oven adjacent the material such that a perimeter of the inner wall surrounds the composite materials; supplying hot air to the hot air distribution manifold via a hot air supply system; directing the hot air towards the composite materials; providing a plurality of hot air exhaust passages in the inner wall so that the hot air moves from the inner chamber to the outer chamber; supplying cold air to the cold air distribution manifold via a cold air supply system; mixing the hot air with the cold air in the outer chamber; directing the mixed hot air and cold air to an exhaust chimney coupled to the outer wall; disposing a cold air distribution conduit inside the exhaust chimney; and supplying cold air to the cold air distribution conduit via the cold air supply system.
