At PROOF Research’s Advanced Composite Division (formerly P2SI) we’re developing next-generation, high-temperature prepregs and advanced composite materials for aerospace, defense and structural applications. Our customers use our novel technologies and advanced materials when superior performance in demanding high-temperature environments requires the most advanced and unparalleled solution available.

PROOF Research’s Advanced Composite Division product portfolio includes state-of-the-art structural polyimide and organic-inorganic resins, prepregs and adhesives with service temperatures up to 1500°F.

We work directly with our customers to create imaginative solutions for manufacturing, process development and materials optimization.


In 2011, PROOF Research’s Advanced Composite Division (then P2SI) was named the Small Business “Supplier of the Year” by Lockheed Martin Aeronautics Company. The award was the result of P2SI’s exceptional support of an Advanced Development Programs project in composite materials. For the project P2SI supplied a complete, high-temperature, advanced composite materials turnkey solution to Lockheed Martin delivering high-temperature prepregs, structural adhesives, high-thermal conductivity composites, tooling and fabrication expertise enabling Lockheed Martin to deliver a prototype, all-composite structure within a time-constrained schedule.
