Abstract
A reinforced composite article includes a first ply, a second ply, and a third ply. A first interface material is between the first ply and the second ply. A second interface material is between the second ply and the third ply. A designated pattern of material property variation, geometric structure variation, spatial variation, or combinations thereof is distributed to selected locations identified in the first interface material or distributed between selected locations identified in the first interface material compared to the second interface material. The pattern is sufficient to measurably vary adhesion, toughness, strength, modulus, or combinations thereof. The article allows distribution of a load across the pattern when the first, second, and third plies receive a force from kinetic energy above a separation threshold by partially delaminating the first ply from the second ply, the second ply from the third ply, or both.
