A Review on Effect of Variation in Material Composition and Structural Dimensions on Vibrational Behavior of Composite Materials

Abstract

Nowadays, there has been a search for alternatives to steel and alloys for several years, to combat the high cost of repair and maintenance of structures damaged by corrosion and heavy use. Structures made from composite materials are rapidly replacing metallic ones in every field because of their high strength- to- mass ratio. The increasing use of tailored composite materials in the design of important structural elements has necessitated the study of vibrational behavior of composite materials. Therefore different materials together are studied and optimum value of their composition and dimensions are to be formulated. This paper mainly deals with effect of variation in material composition and structural dimensions on vibrational behavior of composite materials. Natural frequency increases with jute nano-fiber reinforcement up to 4 wt.% (2214 Hz). Granite-epoxy with 12.5% resin shows highest damping. Addition of cast iron powder improves damping capacity. The damping behavior of various composite materials is studied and results have been formulated above. The effects of different natural and synthetic reinforced composite materials were studied. Natural fibers due to its technical superiority over the synthetic fibers have proved that it is a versatile material for application in rural areas to high tech applications.
