To produce silk fibre composites (SFRPs) with useful properties, three key recommendations from our critical literature review were followed: i) a high-failure strain, low-processing temperature thermoset matrix was used to a) maximise the reinforcing effect of low-stiffness, ductile silk, and b) facilitate impregnation and avoid fibre degradation, ii) high fibre volume fractions were employed to ensure that fibres carried a larger fraction of the load, and iii) given the lack of studies investigating fracture energy dissipation mechanisms in SFRPs, interface modification was avoided due to its complex, sometimes detrimental, effects on toughness. In contrast, nature’s ‘wonder-fibre’ silk has had no commercial applications, and only limited scientific investigations, as a composite reinforcement. With the growing interest in bio-based composites as alternatives to traditional glass fibre reinforced composites (GFRPs), there has been a persistent rise in the commercial use of plant fibre composites (PFRPs). Their potential in future development of different kinds of engineering and domestic products will also be discussed in detail. In this paper, a comprehensive review on different kinds of natural fibre composites will be given. In the biomedical and bioengineered field, the use of natural fibre mixed with biodegradable and bioresorbable polymers can produce joints and bone fixtures to alleviate pain for patients.
Research on biodegradable polymeric composites, can contribute for green and safe environment to some extent. In such concern, the use of renewable resources such as plant and animal based fibre-reinforce polymeric composites, has been becoming an important design criterion for designing and manufacturing components for all industrial products.
Conservation of forests and optimal utilization of agricultural and other renewable resources like solar and wind energies, and recently, tidal energy have become important topics worldwide. Recently, the mankind has realized that unless environment is protected, he himself will be threatened by the over consumption of natural resource as well as substantial reduction of fresh air produced in the world.
