Analysis of thermal diffusivity in aluminum (particle)-filled PMMA compounds

The thermal diffusivity of particulate compounds of polymethylmethacrylate (PMMA) and aluminum powder was evaluated from measurements of temperature in samples during heating in the range of temperature between 100 and 370 K. Samples were prepared with a filler volume fraction of up to 0.15. Results...
