Nano-Phase Powder Based Exothermic Braze Repair Technology For RCC Materials, Phase II

The Phase II project will advance innovative, cost effective and reliable nano-phase exothermic RCC joining processes (ExoBraze^TM) in order to be able to reinforce or repair of space shuttle or other reentry vehicle TPS structures. MRi, Boeing and NASA-Glen Research Center will be partnering to improve exothermic joining process control, to develop preforms that can bond RCC panels in a variety of configurations, to increase the joint strength and demonstrate process robustness, to test joints to validate expected service performance and to scale the joining process in order to fabricate demonstrator components for test and validation. The Phase II effort will look at improved WO3-Al exothermic precursors and develop preform based on polymer bound mats that control the amount of exothermics delivered to the RCC joints. MRi and its partners will develop methods to improve bond strengths through the use of joint prelayers, such as NASA-GRC's GRABER materials or other glass formers. After process improvements are made, MRi and Boeing will, using subcomponents, develop and demonstrate RCC panel repairs, stengthener ribs and panel doublers for as part of its robust RCC efforts. Mechanical and thermal tests will then be designed and conducted to develop more realistic test data on ExoBraze RCC joint performance.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
