Abstract
Primary structures fabricated with carbon/epoxy pre-impregnates has become very popular, especially in aeronautics and automotion. Despite the excellent properties of resistance and stiffness, composite materials present a high sensitivity to impact damage which can cause a sudden drop of mechanical properties affecting the service behavior and reducing the useful life. Here is where damage tolerance concept is introduced.In this work, firstly impact tests have been made in composite lamintes reinforced with carbon fiber, and then, the residual strength for the different stacking sequences have been evaluated using CAI (Compression After Impact) tests.
