Impact Damage in Carbon Composites: Effect of Microstructure

Abstract

The penetration damage created in carbon composites with a range of microstructures has been characterized for both quasi-static and dynamic conditions. Several quasi-static properties of the composites have also been measured. Analyses of the quasi-static penetration have been developed, which appear to present a consistent interpretation of the damage and its relation to the quasi-static properties. A preliminary numerical computation of the dynamic damage has been conducted, with encouraging results. Suggestions for microstructural modifications that should enhance the damage resistance have been made, based on the results of both the observations and analyses.
