摘要

Industrial hemp fibre is one of the strongest and stiffest available natural fibres and therefore has great potential in composite materials. Incorporated into a thermoplastic matrix, it gives a structural material that is cheap, light-weight and recyclable. However, natural fibres are commonly incompatible with common moulding thermoplastics such as polypropylene, which limits the performance of the composites produced. The main objective of the current work was to investigate the use of fungi to treat hemp fibre to create better bonding characteristics in natural fibre reinforced polypropylene composites. X-ray diffraction (XRD), lignin testing, thermal analysis and scanning electron microscopy (SEM), were used to characterise the effect of treatment on hemp fibres. A combined alkali and fungal fibre treatment produced a composite tensile strength of 48.3 MPa representing a 32% increase, as well as increased thermal stability, compared to composites with untreated fibre.
