As a consequence, there is a growing interest in green, environment-friendly materials. As far as composites are concerned, one solution could be to use natural fibres instead of more traditional glass and carbon fibres. Natural fibres are renewable, they are biodegradable in appropriate circumstances and use a biopolymer as matrix. Subject to a Life Cycle Analysis (LCA), the potential advantages of such BioHybrid Composites (BHC) would be:less energy used than with traditional materials;lower pollution levels during production;CO2-neutral processing and burning;photosynthesis of the plant growth fixates CO2 and produces oxygen;no need to use fertilizers and pesticides;lower cost. In composites, natural fibres can compete with synthetic fibres because of their lower density and because they are healthier to work with and less abrasive to the tooling equipment. Their low density and bonded energy makes it possible to recycle laminates. This is the main reason for the automotive industry’s great interest in BHC. Interfacial strength (adhesion) is key to efficient reinforcement. Biofibres have an advantage in the design and manufacture of BHC laminates: compared with pure carbon laminates, which have a “linear” flexural modulus, BHC laminates have a “non-linear” flexural modulus, i.e. better flexural and impact strength than pure carbon-fibre laminates. if u want to short it u can. it's very easy

The types of fibre which are naturally obtained from nature. examples are cotton, jute and silk.
