Structural performances of flax reinforced composites from tannin resins and bio-epoxies

Abstract : Due to the inherent environmental benefits, flax fibre reinforced bio-composites could offer desirable characteristics for load-bearing vehicle parts such as vehicle body panels, crash elements, side panels and body trims. The newly non-woven and woven flax composites based on bio-epoxy and tannin resin were prepared by compression moulding and characterized through quasi-static tensile and low-energy impact testing. Scanning electronic micrograph (SEM) characterization was conducted to understand the tensile failure mechanisms (fibre breakage, fibre pullout and resin failure) and revealed the interfacial adhesion characteristics in the tested composites. The effects of various woven fabric lay-up angles (Balanced, unidirectional, [0°, 90°]₄ and [0°, +45°, 90°, -45°]₂) on mechanical properties were also studied through the authors work. The UD fabric reinforced flax/epoxy and flax/tannin exhibited good structural performance-tensile strength of 220 MPa and 150MPa, respectively, as a result of the longitudinal reinforcement, whereas the impact properties of UD composites are not highly developed.
