Inadvertently, a manufactured laminate is not labeled and the fiber orientations of the layers are unknown. It is known that the layer thickness of the laminate produced using graphite/epoxy is 0.3048 mm and the basic layer properties of the material are given below: Ex = 131 GPa Ey = 11,7 GPa Gxy = 4,82 GPa Vxy = 0,29 To prevent the expensive laminate from being thrown away, an engineer cuts a small strip of material from the edge and applies 3-point bending and tensile tests to the part. The strip is 152.4mm long, 25.4mm wide and 1.83mm thick. 1.83 mm 101.6 mm 3 Point Press Tensile It is known that laminate consists of only 0.45, -45 and 90 degree layers. When the results of the three-point bending test are examined, it is seen that the deformation/load graph is an almost straight line with a slope of 0.03826 mm for low loads. During the uniaxial tensile test, it was measured that a maximum load of 2225N caused an elongation of 0.0941 mm in the sample. What is the layer orientation sequence?
