Biocomposites were prepared using epoxidized linseed oil (ELO) and flax fibre
reinforcements in different assemblies. ELO was cured by two different anhydrides to
check how its thermomechanical properties can be influenced. As reinforcements
nonwoven mat, twill weave and quasi-unidirectional textile fabrics with two different
yarn finenesses were used. Their reinforcing effect was determined in dynamic
mechanical analysis (DMA) in flexure. DMA served also to determine the glass
transition temperature (Tg). Shape memory properties were derived from quasiunconstrained
flexural tests performed near to the Tg of the ELO and its biocomposites.
Flax reinforcement reduced the Tg that was attributed to off-stoichiometry owing to
chemical reaction between the hydroxyl groups of flax and anhydride hardener. The
shape memory parameters were moderate or low. They were affected by both textile
content and type
