Investigation on Mechanical Behaviour of Hybrid Jute/Sisal Fiber Reinforced Polyester Composites

Composite materials are being used in huge quantity in every walk of the life by almost every country throughout the world. By making use of conventional fibers such as carbon, glass and Kevlar, the cost of the products become very high and also the conventional fibers used towards these are not degradable. So attempts are being made to use natural fiber to develop composites, as natural fibers are environmental degradable, non-toxic in nature possess high specific strength, damping properties and better impact resistance. This work is carried out to develop and characterize the non-conventional composites prepared by using locally available jute and sisal fibers as reinforcement and polyester resin as matrix material and to investigate its mechanical properties. The hybrid jute-sisal laminate are prepared by hand lay-up technique and specimens are extracted from the laminates as per ASTM standards and subjected for different mechanical tests such as to obtain tensile strength, impact strength and hardness properties.
