**Abstract**
 This work investigated the effect of maple fibre size and content on the auto-hybridisation of linear low density polyethylene (LLDPE) composites. The samples were compounded by twin-screw extrusion and moulded by compression moulding. Different fibre loadings (5 to 20% wt.), fibre sizes (0-425 microns) and size ratios (30/70, 50/50, 70/30 of short, medium, and long fibres) were used to prepare the auto-hybrid composites with 3% of coupling agent (maleated polyethylene). Micrographs and impact strength results showed that the fracture in auto-hybrid composites is mostly dependent on the longer fibres. At 10% wt. the optimum ratio was 30/70 of shorter/longer fibres, which improved tensile strength (20%), tensile modulus (20%), and impact strength (13%) compared with composites with a single fibre size. But at 20% wt., tensile modulus increased by 30% and torsion modulus by 40% above the rule of hybrid mixtures (RoHM) at a 70/30 ratio of shorter/longer fibres. 68 Refs.
