Abstract

Se proporciona una pieza automotriz de absorción de energía en caso de impacto en una parte frontal o una parte posterior de la carrocería de un automóvil, y que absorbe la energía de impacto al experimentar una compersión axial cuando recibe la entrada de una carga de resistencia al impacto desde la parte frontal o posterior de la carrocería del automóvil, e incluye: un elemento tubular (3) configurado para absorber la energía de impacto al experimentar una compresión axial, en donde el elemento tubular (3) incluye una porción superior, así como porciones de la pared lateral continuas con la porción superior; y una resina (9) que recubre o reviste las primeras superficies exteriores, incluyendo al menos las superficies exteriores de la porción superior y las porciones de la pared lateral del elemento tubular (3). La resina (9) para el recubrimiento o revestimiento tiene un espesor de 8 mm o menos después de ser calentada, forma parte al menos de una porción de la pared periférica de un espacio de sección transversal cerrado y está unida a las primeras superficies exteriores con una fuerza adhesiva de 10 MPa o más.
