Post-Processing Pre-Impregnated Materials within Pre-Cured Matrix

UAH-P-12003-Post-Processing Pre-Impregnated Materials within Pre-Cured Matrix (P2MPM)

Docket: UAH-P-12003

Technology

Today's common advanced composite materials are made of continuous fibers, either graphite or Kevlar, suspended in a polymeric matrix—typically an epoxy of some type. While advances in such composite materials have been steady, there have been relatively few revolutionary changes of late. The investigation and development of a new breed of polymer-enhanced, cementitious composite structures with matrices based on a unique, hybrid blend of inorganic and organic components has the potential to revolutionize structural design.

Researchers at UAH have developed a new construction process called P2MPM. It involves placing a flexible, lightweight cementitious matrix over a pre-impregnated unidirectional graphite tape. A high performance concrete is used so that atomic bonding and molecular interactions occur not only within the concrete, but between the concrete and the reinforcement.

During the P2MPM process, the tape is cured inside the hardened matrix at elevated temperatures. Curing the tape after the cementitious matrix cures results in much stronger bonds within the resulting P2MPM composite. The greater stiffness ratio and lighter weight associated with the building technology offer design engineers more flexibility than that afforded by advanced composite materials.
