Innovative Approach for High Strength, High Thermal Conductivity Composite Materials

The proposed Phase II innovation for a pitch fiber composite will make it possible to achieve the stated mechanical and thermal performance goals of the solicitation: 1) comparable mechanical performance to a state-of-the-art toughened epoxy/PAN carbon fiber composite; and 2) transverse thermal conductivity greater than 20 W/mK with an objective of 50 W/mK. The material technology developed under this project will be generally applicable to a broader range of fiber reinforced composite materials and represents a new class of hybrid engineering materials with great commercial potential. BENEFIT: The materials technology developed in this proposed Phase II SBIR project will provide revolutionary thermal and thermal-structural performance for Air Force systems, including space satellites, missiles, and air vehicles. The materials technology will also have great impact across a wide range of industries where high thermal performance, lightweight, and mechanical integrity are design requirements.
