Studying The Importance of Evaluation And Determination of Volume Fraction Values For Wound Glass And Carbon Fiber Reinforced Composites


The wide and increased use of the composite materials in industry especially intoimportant applications such as pipes and pressure vessels tends to give the study oftheir properties more importance, so results will be presented from a series of tests onthe physical properties of composite materials . Specimens cut from pipes made fromcomposite materials to be tested under internal pressure loadings have been tested byusing a series of ASTM D2584 (1968) standards test methods for glass fiberreinforced composites and the density method for carbon fiber reinforced composites.The results from this series of tests have been tabulated and presented. The volumefraction for the glass and carbon fibers were found to be 0.476 and 0.540,respectively.
