Abstract : In recent years, there has been a growing interest toward the use of natural fibre composites for structural
applications. Previous studies have been found that natural fibre exhibited comparable specific mechanical properties to
glass fibers. However, the main drawbacks of flax fibre are high water absorption, variability in mechanical properties, and
poor adhesion to various matrices. Combining natural fibre with synthetic fibre will potentially improve the overall
properties of flax fibers. In this work, woven carbon/flax/epoxy hybrid composites were manufactured with two flax fibre
configurations, namely unidirectional [0CF2/0F6]s and angle-ply [0CF2/±45F6]s. The manufactured specimens were
characterized using water absorption, tensile, compression, flexural, Rockwell hardness, and torsion tests. The findings of
this study showed significant improvement resulting in less water absorption to neat flax composite (17% for neat [0F8]s vs
4.84% for [0CF2/0F6]s, and 8.32% for [0CF2/±45F6]s) . In addition, the compression, tensile, hardness, and torsion properties of
the hybrid composite specimens were improved by more than 50% in average compared to those of pure flax/epoxy
composite specimens.
