Damage Tolerance Assessment Procedures for Composite Materials and Components

Abstract : The effect of localized impact damage on the general reliability of composite constructions is of concern in a variety of contexts. The advantages of using instrumented impact test procedures and enhanced data acquisition techniques to quantify the level of damage are illustrated for some specific applications. Using this approach the extent of the damage can then be characterized for controlled and reproducible impact conditions. The procedures outlined and the flexibility they offer in imparting damage to materials or components provide the basis for a constructive damage tolerance methodology.
