Polymer composites

Polymer composites are materials made by combining polymers with fibers or fillers. Natural fiber composites are an environmentally friendly type of polymer composite that uses plant-derived fibers like wood, sisal, hemp or cotton instead of fibers like fiberglass. They have been investigated since the 1960s for uses like repairing existing structures. Natural fiber composites are lightweight, can be produced with low energy, and sequester carbon dioxide. They provide benefits like strength enhancement, durability, and a replacement for steel with lower stiffness. However, there are challenges to wider adoption like a lack of experienced designers and higher short term costs. The construction industry is a major consumer of polymer composites, especially for non-load bearing

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
 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.
