A Hybrid Effect on the Bending Behaviors of CFRP-Al Composites with Anisotropic Characteristics

Abstract

Recent development of carbon fiber and its hybrid composites with metals has required the analysis of the deflection characteristics of the beams made of these materials under bending load of short duration.
It was found that the deflection of the specimen of CFRP-Al composite under four-point bending could be satisfactorily predicted by the finite element method assuming anisotropic and isotropic characteristics for carbon fiber and aluminum, respectively. The volume fraction of the reinforcement and the order of laminations have a marked influence on the relative stiffness. An optimum design for each of various applications may be achieved by considering such influence.
