Investigations on the Flexural Strength and the Effect of b/h and l/b ratio on the Carbon Fiber Reinforced Epoxy Laminated Composites

摘要

In present day the use of fiber reinforced composites is increased remarkably in the various sectors of industries owing to its relative advantages especially in industries like aeronotics, automobile, ship buildingand in chemical industries, where the major emphasis is on weight reduction with a subtantial increase in the mechanical strengtudh of the component with enhanced durabliudty by having properties like corrosive resistance, udanti reactive to various acidic reactions and to udwith stand various climatic and temperature conditions.In this context carbon fibre reinforced laminated composites exhibit excellent mechanicaludproperties.Investigation of various properties is difficult in composite materials because of its complex udbehavior further it is very difficult to evaluate the behavior of fiber laminated composites becauseudof its enhanced complexity,evaluation of propertiesudin composites is difficult with the addition of the fiber (carbon fiber)into the matrix. in this paper an investigation on the flexural properties of the carbon fiber reinforced laminates is carried out and the effect of bredth(b)to thickness(t)and the influence of the of length(l)to breadth(b),Aspect ratiois being evaluated and appropriate conclusions are drawn.
