Impact of Fiber Loading on Injection Molding Processing Parameter and Properties of Biocomposite 2010-01-2026

The research on using natural fibres as the reinforcement in plastic composites has increased dramatically in the last few years. Flax fibres are renewable resources with low specific mass, reduced energy consumption, and relatively low in cost. These advantages make flax fibres recognized as a potential replacement for glass fibres in composites. Among plastic, polyethylene was concluded to be a suitable material used as matrix in natural fibre reinforced biocomposites. However there are few studies on this area so far. In this paper, the processing method of flax fibre-reinforced polyethylene biocomposites is introduced. Flax fibre polyethylene biocomposite consists of flax fibre as the reinforcing component and high density polyethylene as the matrix. Acrylic acid pre-treatment was applied to flax fibre to improve the bonding between fibre and polyethylene. Extruding was used to mix materials and injection molding technique was carried out to process materials to certain shape biocomposites. The injection temperature and pressure were studied during injection molding to determine appropriate processing parameters for the biocomposites at different fibre content.
