Enhancement of impact toughness and damage behaviour of natural fibre reinforced composites and their hybrids through novel improvement techniques: A critical review

The importance of natural fibres over synthetic have gained significant attention in the research area, due to their higher specific strength, stiffness, lightweight and inexpensive. Natural fibre composites used various applications are often susceptible moisture absorption critical loadings scenarios during service life such as low-velocity impact damages which is a concern for structural non-structural applications. For enhancing toughness hybridisation with essential. This paper examines essential information critically from published literature influencing morphological characteristics, fracture toughness, damage tolerance resistance reinforced hybrid composites. Following this, this review analyses novel improvement techniques suitable behaviours.
