Abstract The objective of this study is to develop expanded composites of poly(ethylene-co-vinyl acetate) (EVA) filled with two vegetable reinforcements (banana fiber or wood flour) as well as to evaluate the influence of the type, size and concentration of these reinforcements on the cell growth and their morphological, mechanical, thermal and physical properties. The results indicated that the natural fibers act as nucleating agents and affect the cells stability during the formation of the cellular structure in the expanded composites. The mechanical properties of the expanded composites are directly related to the composite expansion degree. Comparative results of the use of vegetable residues indicate that wood flour reinforcement provides more homogeneous cells, while banana fibers restrict the expandability of the composite and its density.
