Abstract:

With anticipated increased use of composite materials in aerospace structures and other applications, thermal properties of composites are needed as essential design information. In the past there was only scanty amount of research effort in thermal analysis of composites, as most of the work has been concerned with their mechanical properties. This report contains results from a rigorous analysis to determine steady-state effective thermal conductivities of fiber-matrix type of composites. The fibers bundled into twos are considered dispersed in a matrix of resin. The dispersion patterns of configurations considered are 1 uni-directional fibers in a matrix, as the simplest geometry, and 2 0.90 configuration in which two uni-directional tapes are overlaid at 90 degrees to each other. The method of analysis is to solve a two-region steady-state heat conduction equation either analytically or numerically. The analysis assumes a prior knowledge of the geometry of a composite and the constituents thermal conductivities.
