Abstract
A ballistic composite armor article includes a multi-layer hard armor sheet that has at least first and second unidirectional yarn monolayers. The second unidirectional yarn monolayer is transversely oriented with respect to the first unidirectional yarn monolayer, and there is at least one polymeric binder layer arranged adjacent to and stabilizing at least one of the first and second unidirectional yarn monolayers. The yarns of the first and second unidirectional yarn monolayers include respective fiber bundles that have a lateral spread factor ranging from negative lateral spread to a positive lateral spread of less than 306%.
