Effect of a Preliminary Impact on the Mechanical Properties of a Structural Carbon Fiber Reinforced Polymer during Interlaminar Shear
摘要
Abstract—The influence of an impact on the mechanical behavior of a carbon fiber reinforced polymer is investigated using interlaminar shear tests of a short beam with a simultaneous registration of acoustic emission signals. Displacement and deformation fields detected by digital image correlation have also been studied. The influence of the preliminary impact energy on the change in damage mechanisms is revealed, and deformation localization in the material is detected.
