METHOD AND APPARATUS FOR DETERMINING INTERLAMINAR SHEAR MECHANICAL PROPERTIES OF COMPOSITE LAMINATES

摘要

Method and Apparatus for Determining Interlaminar Shear Mechanical Properties of Composite Laminates A method and apparatus for testing interlaminar shear mechanical properties of composite laminates. The method involves preparing an elongate rectangular specimen and mounting said rectangular specimen longitudinally with three equally spaced contact points against a first surface and two contact points against the opposing, second, surface. A load is applied via the contacts to the specimen until the specimen delaminates indicated by an audible crack. Displacement of the specimen is measured at an inner region of the specimen at a section of pure shear. This measurement can be used to accurately determine interlaminar shear strength and modulus so the failure properties of the material are known for design consideration.
