Fibre Composites
Under investigation since the 1960’s
repair of existing structures
Bonds well, Easy to shape, enhancement of strength, Low stiffness, Durability.
Rehabilitation & retrofit.
replacement for steel.
• fibre reinforced polymer
Natural Fibre Composites
Combine plant-derived fibres with a plastic binder
Wood, sisal, hemp, coconut, cotton, flax, jute, abaca, banana leaf
Light weight, low-energy production and sequestration of carbon dioxide
Semi-skilled indigenous workers
Removes concern about the potential of lung disease by glass fibre
Bio Composites
formed by a matrix (resin) and a reinforcement of natural fibres.
environment-friendly biodegradable composites to biomedical composites.
Characterised by the petrochemical resin replaced by a vegetable , animal resin or the bolsters (fiberglass, carbon fibre or talc) are replaced by natural fibre (wood fibres, hemp, flax, sisal, jute...)

Specific strength and specific stiffnessLow stiffnessTailorable mechanical propertiesDurabilityBetter DurabilityLower maintenance costsNon-critical applications such as baths and
vanities.
Present Scenario Largest Consumer is Construction Industry. High use in Non-load bearing applications. Reinforced polymer composites (RPCs)
(LOAD BEARING APPLICATIONS) Rehabilitation and Retrofit Less Environmental Hazardous (no
resources)
Long Term View Enormous Effort to migrate to polymer
composites. Cradle to the Cradle approach Increase use of natural fibres(diversify). Does not cause pollution. Environmental sustainability.
Non-renewable natural resources and lower embodied energy are safe.
