Natural fibre reinforced epoxy composites: determination of fibre volume fraction, fibre mechanical properties and fibre cross-section variability

In recent years there has been a growing renewal of interest in the research and development of fibres from natural sources as potential reinforcements for high performance composite materials. This increased interest in natural fibre composites has multiple drivers such as, growing concern for the environment, possible cost competitiveness, and concerns around the sustainability of materials production. It has been claimed that natural fibres show significant potential as environmentally friendly alternatives to conventional reinforcements such as glass fibres. A number of natural fibres have been identified which appear to have some appropriate mechanical properties for structural purposes, being of low density, and high specific strength and stiffness.
