Fast Curing Modular Composite Patch System for Field Applications

SOCOM requires a method to field repair multiple materials as well as to mount armor and related hardware for a variety of tactical purposes with a composite material. To address this need, we propose application of a “Modular UV Patch” (MUVP) system that incorporates ultraviolet curing resin systems and an innovative technique for delivering the UV light through optically lossy fibers that form a composite material. This patented modular patch system will be self-contained, easy to use, and provides rapid curing (seconds) while also providing a capability for underwater applications. The UV based resin systems offer increased shelf life, and elimination of special storage facilities, with a minimal “tail” of supporting equipment while maintaining the strength associated with both conventional thermal cures and competing bonding compounds. The focus of this Phase I effort is on the demonstration of a rapid strong single-step UV curing process and its assessment for damage tolerance and underwater adhesion as well as its optimization for a wide range of field applications. Comparisons with competitive sealant and adhesive compounds will also be made and an agenda determined for Phase II development of the MUVP system.
