Abstract : This report contains comparisons of experimentally measured and theoretically calculated temperature distributions in honeycomb structural panels filled with a low diffusivity foam. The theoretical method involves the use of the three-dimensional Thermal Analyzer computer program, a product of Lockheed Aircraft Corporation. The experimental procedure consists of subjecting the composite honeycomb panel to heat fluxes of 1000 to 3250 watts/foot2 and recording the temperature responses. The data presented herein indicate that the three-dimensional theoretical method is effective in predicting the temperature distributions in a composite panel. For a special case considered, the simpler flat- plate, finite-difference method gave rather inaccurate temperature predictions at the later test times. (Author-PL)
