Si-O-C Aerogels for TPS of Reentry Vehicles, Phase II

NASA has expressed a need to identify and develop breakthrough technologies that have potential to provide increased scientific return at lower cost, and to enable missions and capabilities beyond current horizons. To make these missions feasible, advanced thermal materials are needed as thermal protection system (TPS) materials for reentry. For this Phase II SBIR project, Aspen Aerogels Inc. proposes to develop particularly innovative, lightweight silicon oxycarbide aerogels (SiCxO2-2x) that will advance the state-of-the-art for thermal protection systems (TPS) for reentry vehicles. Aerogels are lightweight materials with exceptional insulating capabilities. Because of their low thermal conductivities and lightweight, the inclusion of aerogel based insulation materials in TPS will result in significant weight savings over the current baseline construction. During the proposed effort we will optimize the aerogel composites developed during the Phase I effort for use as high temperature insulation for reusable launce vehicles. The Phase II program will focus on complete characterization and testing so that aerogels can be qualified for use as insulation materials on reentry vehicles. The mechanical, and thermal properties of the silicon oxycarbide aerogels will be fully characterized, and a low-cost, environmentally benign manufacturing process will be used.

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.
