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
Combine plant-derived fibres with a plastic binderWood, sisal, hemp, coconut, cotton, flax, jute, abaca, bananaleafLight weight, low-energy production and sequestration ofcarbon dioxideSemi-skilled indigenous workersRemoves concern about the potential of lung disease by glassfibre
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...)
Lack of designers experienced Processes Analytical hierarchical process Whole of life process Cost Short Term Cost Direct costs Fabrication Cost Costing of fibre
Specifications Specific strength and specific stiffness Low stiffness Tailorable mechanical properties Durability Better Durability Lower maintenance costs Non-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)
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.
