kinetic energy absorption method and composite, reinforced, kinetic energy absorbent article

摘要

A reinforced composite article includes a first fold, a second fold, and a third fold. A first interface material is between the first fold and the second fold. A second interface material is between the second fold and the third fold. A projected pattern of material property variation, geometric structure variation, spatial variation, or combinations thereof is distributed to selected locations identified in the first interface material compared to the second interface material. The pattern is sufficient to measurably vary the grip, strength, strength, modulus or combinations thereof. The article allows the distribution of a charge across the pattern when the first, second and third folds receive a kinetic energy force above a separation limit by partial delamination of the first fold from the second fold, the second fold from the third fold. fold, or both.
