Tensile Behaviour of BBJS Composite Materials

Abstract––In the past two decades the usage of composites is increased significantly among all composites natural fiber as reinforcement in polymers is replace many engineering materials. In present work deals making a composite of natural fibers like Banana, Borassus, Jute and Siasal (BBJS) as fibers and give a brief explanation of advances and characterization of new set of natural fiber composites. It has prepared by reinforcing BBJS fibers with epoxy resin and hardener in matrix by using hand layup technique. The reinforcing material may be in the form of fibers, particles or flakes. Reinforcement usually adds rigidity and greatly impedes fracture promulgation. Skinny fibers can have high potency, and provided they are mechanically well attached to the matrix they can greatly improve the composite's overall properties. Fibres are used to carry the load and matrix is used to bind and transmit the load to fibers. The natural fibers were prepared from the raw material by retting and combing process.Composites were prepared as cylindrical shape by using BBJS as fibers of 1:1:1:1, 1:2:2:2, 2:1:2:2, 2:2:1:2 and 2:2:2:1 weight fraction. The tensile properties of composite were estimated after destructive testing the addition of borassus is drastically changes the properties. Key words: BBJS fibers, epoxy resin, tensile properties,
