A composite panel includes a support layer including a first plurality of prepreg plies wrapped around at least one mandrel; a mid-plane impact layer including a second plurality of prepreg plies, the mid-plane impact layer adjacent to the support layer; a upper skin layer including a third plurality of prepreg plies, the upper skin layer adjacent to the mid-place impact layer; and a lower skin layer including a fourth plurality of prepreg plies, the lower skin layer adjacent to the support layer; whereby each of the first, second, third, and fourth plurality of prepreg plies are co-cured to form the composite panel.

Impact resistant composite panel and method of forming a composite panel

A laminate design is provided and includes a substrate formed to define through-holes, an initially uncured pre-preg laminate disposed proximate to the substrate and an initially uncured pre-preg staple. The staple includes a main member and legs extending from the main member and being disposable with the legs extending through the through-holes to pierce the laminate. The staple is co-curable with the laminate.
