This is a unique X-ray atlas illustrating damage in composite plates caused by non-penetrating impacts. A valuable aid in designing composites for different types of impact resistance. Damage to composite materials caused by non-penetrating impact is often internal, invisible and difficult to detect. This atlas contains more than 400 revealing pictures of impact damage from a variety of loads under a variety of conditions. The parameters are varied systematically to produce useful, reliable design data.
