Impact-Initiated Damage in Laminated Composites.

Abstract

Due to the advantage of high strength to weight ratio, composite materials are being increasingly used in the design of aircraft components and structures. One of the problems that needs to be studied in detail in such applications is the effect of projectile impact on the strength carrying ability of composite structures. The mechanism of impact-induced crack propagation is not fully understood, yet. In the past few years, numerous efforts have been made to predict theoretically the residual strength of the high performance fiber composite materials subjected to foreign object damage (FOD).
