Natural Fiber Reinforcement Composite
It is a type of Fiber Reinforced Composite, in which natural fibers are dispersed into a polymer matrix.
They are renewable, cheap, completely or partially recyclable and biodegradable.
Natural fibers are incorporated into a matrix material such as thermosetting plastics, thermoplastics or biopolymers.
Natural fibers being eco-friendly, lightweight, strong, and low cost have already started to replace glass fibers in numerous engineering applications in automobiles, furniture, packaging, and construction etc.
What Is Natural Fiber ?
All fibres which come from natural sources (like plant, animal, etc.) are called as natural fibers.
Natural fibres are greatly elongated substances produced by plants and animals.
Lignocellulosic natural fibres are an excellent raw materials for production of wide range of composites for different applications.
Classification Of Natural Fibers
Difference Between Natural Fiber And Synthetic Fiber
Natural Fiber Synthetic Fiber
All of the natural fibers come from the nature These are completely man made
Fibers are found in staple or filament form It is found in filament form
Length of the fiber is nature given Length of the fiber is controlled by man
It is not possible to change in fiber structure It is easy to change in fiber structure
Comparatively less durable then synthetic fibers These are more durable then natural fibers
These are environment friendly Some fiber are harmful for the environment
Use of natural fibers are limited then synthetic fiber
These are used in multi task then natural fiber
Growth with its natural colors Colors are added in solution bath as required
Classification Of Polymer Matrix
Advantages
Renewable
Recyclable
Eco-friendly
Light weight
Low cost
Acceptable specific strength properties
Better wear protection
They display acoustic insulation and absorb vibrations and large quantities of energy when subjected to destruction.
Reaction to fire of composites based on natural fibres is much more beneficial comparing to polymers
Disadvantages
Moisture absorption, which causes swelling of the fibres.
These are UV-sensitive.
Lower durability.
Low impact strength
Fibre degradation during processing.
Fibre treatments can improve this considerably.
Applications
Automobiles
Furniture
Packaging
Construction
Electronic Component
Marine
Aerospace
Consumer products
The main drivers for use of natural-fiber based composites in automotive applications
Demands for lightweight parts, which leads to a lowering in fuel consumption
Acceptable mechanical properties, good acoustic properties.
Good recycling possibilities of the components made with thermoplastic polymers, reducing the waste disposal problem
Technical benefits such as lower energy loss, longer lifetime of tools, better wear protection etc. can be converted into cost saving potential.
Competitive pricing- Automotive industries have developed using composites with non-wood fibers such as flax and hemp, as well as cellulosics, as an alternative to fiber glass. The resultant composites are lighter, and the natural fibers used by the car industry (VW/Audi, BMW) to produce interior door panels, parcel shelves, dashboards, etc., are competitively priced compared with fiberglass
