Abstract

La estructura para absorber energía de impacto comprende un núcleo (15) que tiene una primera superficie (10) expuesta a impactos y refuerzos que se distribuyen dentro del núcleo (15) y tienen interfaces de fricción con el material del núcleo. Los refuerzos comprenden primeros refuerzos (16) que se colocan en una primera zona reforzada (12) adyacente a la primera superficie (10) y tienen direcciones principales de resistencia que forman un ángulo de menos de 45° con la primera superficie.The structure for absorbing impact energy comprises a core (15) having a first surface (10) exposed to impacts and reinforcements that are distributed within the core (15) and have frictional interfaces with the core material. The reinforcements comprise first reinforcements (16) that are placed in a first reinforced zone (12) adjacent to the first surface (10) and have principal directions of resistance that form an angle of less than 45° with the first surface.
