In this study, with 0-15% moisture contents, Saskatchewan grown seed flax fibers are used as reinforcement in polyethylene matrix for the production of rotational molding components. The components were prepared at Parkland Plastics in Saskatoon, SK by rotational molding process. About 0-30% by weight, treated flax fibers of 2-3 mm length were incorporated with linear low-density polyethylene in order to make the component. Mechanical properties were investigated as a function of moisture presence in flax fiber. Mechanical properties and consistency of the products can be improved by reducing the moisture content of the flax fiber. Scanning electron microscope (SEM) analysis demonstrated the improved interfacial bonding achieved by reducing the moisture content in flax fiber. Flax fiber of low moisture contents appears to adhere strongly with polyethylene. A chemical treatment can be designed for the flax fiber to ensure better moisture resistance and consistency of the end products. The present study has shown that the influence of moisture within the flax fiber incorporated in polyethylene matrix for the rotational molding products have negative impacts on bonding between fiber and matrix as well as consistency of the end products. The low moisture content flax fiber with LLDPE and HDPE composite has improved the mechanical properties and consistency of the products, as expected.
