Summary
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.
