Abstract
In this paper, three-point and five-point bend tests for evaluating the interlaminar shear strength (ILSS) of carbon fiber aluminum laminates (CFML) are investigated. CFML is a kind of fiber metal laminate (FML) and consists of carbon fiber reinforced polymer layers and metal layers. Aluminum alloy sheet of 0.5 mm thickness is selected as the metal. General formulae for the evaluation of ILSS of CFML from three-point and five-point bend tests are presented. Three-point and five-point bend tests and elastoplastic finite element analysis are conducted and the results of two kinds of bend tests are compared. It is found that five-point bend test gives more accurate evaluation for the ILSS of CFML than three-point bend test in the case of that the interface is not located at the neutral plane.
