Thermally Conductive Structural 2D Composite Materials.

摘要

Report developed under STTR contract for topic number AF10-BT01. The recent Small Business Technology Transition (STTR) program was focused on the thermal property enhancement of polymeric composites using various functionalizations and treatments of pitch carbon fiber surfaces. The pitch based carbon fibers were first reacted with a maleic anhydride solution to increase the functionality of the fiber surface. The reactive surface was then treated with four various primary amine structures that would provide a surface coupling to the polymeric matrix. The surface chemistry was evaluated at each stage by X-ray Photoelectron Spectroscopy (XPS). Both two-dimensional and three- dimensional fiber constructions were evaluated with epoxy and polyimide based matrix resins. All results and findings are included in this Final Technical Report.
