Assessment of Spatially-Reinforced Carbon Composites Exfoliation after a Low-Speed Impact

A method of evaluation of composite materials damage after a low-speed impact. Mechanical properties of six types of carbon-carbon composite materials have been investigated under compression, lateral bending and shift before and after the impact action. Obtained results were analyzed and the proposed method acceptability was evaluated. FE calculation was performed to determine the interrelation of impact energy and the size of a zone of possible exfoliation and stress intensity
