A bio-based thermoset resin was reinforced with flax fabrics and Lyocell fiber. The effect of different weave architectureswas studied with four flax fabrics with different architectures: plain, twill (two different types), and dobby. The effect ofthe outer ply thickness was studied and characterized with flexural and impact testing. Composites manufactured withplain weave reinforcement had the best mechanical properties. The tensile strength, tensile modulus, flexural strength,flexural modulus, and impact strength were 280 MPa, 32 GPa, 250 MPa, 25 GPa, and 75 kJ/m2, respectively.Reinforcements with twill-weave architecture did not impart appreciable flexural strength or flexural modulus evenwhen the outer thickness was increased. Plain- and dobby (basket woven style)-weave architectures gave better reinforcingeffects and the flexural properties increased with an increase in outer thickness.Water absorption properties of thecomposites were studied and it was observed that the hybridization with Lyocell fiber reduced the water uptake. Fieldemissionscanning electron microscopy was used to study the micro-structural properties of the composites.
