Swelling of Plant Fibers under Hygro/Hydrothermal Conditions: Determination of Hygro/Hydroexpansion Coefficients

Abstract : The mechanical behavior of biocomposites and their durability are influenced by the intrinsic properties of the natural fiber reinforcements, especially their high sensitivity to hygro/hydrothermal conditions. To better understand these phenomena, the effect of humidity conditions on the moisture and dimensional variations of natural fiber bundles from several botanical origins with contrasting biochemical and structural characteristics was studied. Results evidenced differences in water uptake and swelling as a function of plant species and allowed to determine hygro/hydroexpansion coefficients of fiber bundles, thus opening interesting perspectives for the predictive modeling of “in-service” mechanical behavior of biocomposites.
