| Abstract: |
| In recent years there has been interest in
using flax fibres to produce composites because of a
number of attributes, including low density, biodegrad-
ability and high mechanical properties. It was found that
treatment of flax fibres may be required to improve the
bond quality with a resin. These treatments also have an
impact on the properties of the fibres themselves. The
objective of this project was to evaluate the impact of
three treatment methods on the mechanical properties of
flax fibres. The three treatment methods were alkaline,
enzyme and steam-heat. After treatment, flax fibres were
tested in tension using a universal test machine. Results
showed that tensile strength and Young’s modulus of
flax fibre can be enhanced significantly by the three
treatment methods, compared with untreated flax fibres.
Enzyme treatment was shown to be the best approach to
improve mechanical properties of flax fibre than alkaline
and steam-heat treatment |
