Abstract: | The test methods that were proposed, for studying the shear properties of composite materials, are numerous, but varied and controversial. As a consequence, there is no method globally accepted at this aim. Nevertheless, one can accept that some methods are considered more suitable for nonhomogeneous and nonisotropic materials. In that meaning, the test method that was created by professor Iosipescu is one of the main shear tests, at this moment, and as a result it was adopted as a ASTM Standard test method. This paper presents some experimental results, obtained by applying that method on some carbon/epoxy fiber reinforced composites |
