Abstract
Measurements of thermal diffusivity α by laser flash method (LFA) have been performed on polypropylene-iron composites with filler particle content from 10vol.% to 70vol.% at temperatures from 305K to 410K. Experimental data of thermal diffusivity have been compared with existing mathematical models whereas best congruent fit is a model by Hashin and Shtrikman. Additionally to composites containing randomly distributed filler material, composites containing aligned particles where produced. LFA measurements where performed on samples in longitudinal and perpendicular direction of particle alignment. Values of thermal diffusivity in longitudinal direction of alignment where always higher than unaligned samples and in perpendicular direction of the alignment, respectively, with a maximum of 1.64: 1 (αlongitudinal: αunaligned) at a filler content of about 30vol.%.
