Abstract: In this work, the mechanical properties including tensile strength, flexural strength, impact strength and fracture toughness of the PLA/hemp composites were investigated over a range of fibre content (0-30 wt.%). It was observed that, the tensile strength and Young's modulus of the composites increased with increased fibre content. The flexural strength did not increase with fibre reinforcement, however, the flexural modulus of the composites increased significantly. Impact strength of the composites increased up to 20 wt. % fibre loading, however, further increased fibre loading caused a reduction of impact strength. KIc and GIc values decreased with increased fibre content.
