Hygrothermal effect on moisture kinetics and mechanical properties of hemp/polypropylene composite: Experimental and numerical studies

17.03.2015 | Lotfi Toubal, Jean‐Christophe Cuillière, Karim Bensalem, Vincent Francois, Papa‐Birame Gning, Polymer Composites, 2015

The exposition of thermoplastic composites reinforced with natural fibers to moisture and heat is likely to lower their mechanical properties and restrain their use in the design of parts. The present work is focussed on investigating the effects of hygrothermal aging on the mechanical behaviour ...
