About this opportunity
Navy SBIR topic — Accepting submissions 2026-12-02 to 2027-01-06. Current composite airframe repair methodologies rely on a combination of wet-layups, B-staged epoxy prepregs, and bonded pre-cured thermoset patches. While pre-cured patches are the standard for high-quality depot repairs due to their autoclave-consolidated strength and “inspectability”, they present significant operational and logistical limitations. All these traditional methods require secondary adhesive bonding (using paste or film adhesives) to attach the repair to the airframe. This secondary bond is the inherent weak link of the repair, demanding long thermal cure cycles (often 4 to 24 hours), strict environmental controls, and burdensome cold-storage logistics (freezers) for the B-staged resins and adhesives. Furthe...
