Composite materials are widely used in automotive, aerospace, wind energy, electrical, sports, marine, domestic usages, constructions, medicine, chemical industries etc.
This paper reviews the tensile properties of natural fiber reinforced polymer composites.
Natural fibers have got the attention of researchers, engineers and scientists as an alternative reinforcement for fiber reinforced polymer (FRP) composites.
They are used as a replacement for the conventional fibers like glass, aramid and carbon as they cost low, have good mechanical properties, possess high specific strength, non-abrasive, eco-friendly and biodegradable characteristics.
The tensile properties of natural fiber reinforced polymers (both thermoplastics and thermosets) are mainly influenced by the interfacial adhesion between the matrix and the fiber.
Many chemical modifications are used to improve the interfacial matrix–fiber bonding which results in the enhancement of tensile properties of the composites.
Generally, the tensile strengths of the natural fiber reinforced polymer composites increase with the fiber content up to a maximum or optimum value, and then its value drops. But Young‘s modulus of the natural fiber reinforced polymer composites increases with increasing fiber loading.
Researchers concluded that polymer composite materials have wide advantages & application in various industries.
