Tensile behavior of aluminum reinforced with angle-ply boron epoxy laminates

An experimental investigation of the tensile behavior of aluminum reinforced with angle-ply boron/epoxy laminates was conducted. It is shown that the ultimate stresses of a wide variety of laminate configurations fall within a very narrow range of values. Some configurations of composite reinforced aluminum laminates exhibited higher ultimate stress values than the corresponding all composite laminates while other configurations exhibited lower ultimate stresses than the corresponding all composite laminates. Elastic moduli and Poisson ratios agreed quite well with predicted values but strength predictions were inconsistent.
