Polymer composites based on agave fibres

Low density polyethylene was blended with agave fibres of three sizes: 0.21, 0.81 and 1.11 mm. Fiber concentrations between 10 and 25% were used to produce composites using twin-screw extrusion and injection molding. To determine the effect of processing on mechanical properties, uniaxial traction and impact resistance were obtained, in relation with morphology and density. The results show that there is an optimum concentration and fibre length for each processing technique
