Abstract. Laminated composites based on the new thermoplastic Elium 188 from Arkema and woven flax fibers has been manufactured by the infusion process at room temperature, still yet reserved to thermoset-based composites. The low velocity impact behaviour has been investigated between energy 7 to 22J for two stacking sequences [0/90]6 and [±45]6.Repair after impact has been investigated too. The impact resistance was established by measuring load, deflexion, absorbed energy, contact duration and damage. Visual, high-speed images and microscopic observations were performed on impacted samples to show the effect of incident energy on the damage extension in the composites, by revealing the fiber/matrix debonding as principal damage mode. 3 points bending tests were carried out to assess the residual impact performance. In addition, a simple thermo-compression damage repair process was applied to carry out the multiple impact/repair cycles on the impacted plates. A significant recovery of stiffness and maximum impact force up to 4th cycle at 4J of [0/90]6 plate has been revealed, by highlighting the interesting potential of flax/Elium® bio-composite to its repair aptitude.
