During the last decade there has been a renewed interest in the natural fibre as a substitute for glass in modern engineering composite materials. Discuss the reasons behind this upsurge in demand for natural fibre composites. Consider the properties and applications of these materials and analyse the benefits and drawbacks associated with.
