Conventional composite repair technologies utilizing electrical heat blankets are generally limited to flat or near flat surfaces and not feasible for irregular shapes or double contoured surfaces. Currently a need exists in developing a new heating system that is capable of applying controlled heat to advance the curing of resin systems in the repair of complex shaped structures and larger areas. A new heating system capable of achieving higher temperature cures over a larger irregular geometry is proposed. The proposed tasks include evaluation of existing technology, design and analysis of prototype heating system, and performing a market search. Details of each task, related work and key personnel are described in the proposal. The result of these tasks will lead to development of a new heating system for the repair of U.S. Navy and commercial aircraft made of high temperature composites.
