Abstract: The bending behavior and damage characteristic of CALL hybrid composites were studied by moire interferometry.The shear strain distributions over the cross-section and the forms of damage of bending beams were obtained.The results show that the magnitude of the shear strain in the carbon fiber/epoxy laminate is clearly larger than that in the correspondent aluminium laminate,and the shear strain distribution over the crosssection of carbon fiber/epoxy laminates conforms basically to a parabolic distribution curve in the same way as that of aluminium laminates.Shear damage either in interlamination or in carbon fiber/epoxy laminates and tensile failure of carbon fiber/epoxy laminates in the tension surface represent,respectively,the damage forms of the longitudinal and transverse bending specimens.
