Impact on composite structures
G. A. O. Davies,Robin Olsson +1 more
TL;DR: The problem of impact damage in laminated composite structures, and the consequent reduction in residual strength, has been a topic of continual research for over two decades as mentioned in this paper, and the number of journal papers on the subject now runs into four figures and most have been conscientiously reviewed by Abrate.

Impact and delamination failure of woven-fabric composites
Jang Kyo Kim,Man Lung Sham +1 more
TL;DR: In this paper, an overview of the fracture behavior and failure mechanisms of composite laminates containing woven fabrics in mode I and mode II delamination and under impact loading is presented, where potential advantages of using woven fabrics as opposed to cross-ply unidirectional prepreg tapes are discussed from the viewpoint of the microstructure/property relationship.

Instrumented Impact and Static Indentation of Composites
Shaw Ming Lee,Paul Zahuta +1 more
TL;DR: In this paper, the impact behavior of several laminate systems has been studied, defined by impact force, damage size and energy absorption, and it was found that the damage growth process during impact as the force surged to its maximum value can be visualized from the static indentation damage induced at incrementally increased force levels.
