Abstract

L'invention concerne une composition énergétique pouvant se mettre à feu sous l'effet d'une chaleur générée lors de l'application d'une énergie électrique; la composition comprend une matière d'allumage se mettant à feu en réaction à l'application de chaleur et contenant moins de 5 % en masse d'une matière résistive, de préférence des nanotubes de graphite. Cette matière comporte des brins d'une largeur de préférence inférieure à 2 microns et d'une longueur sensiblement supérieure à la largeur. Les brins de matière résistive sont dispersés dans la composition énergétique de façon à créer des chemins conducteurs qui, à l'application d'une énergie électrique suffisante, génèrent une chaleur suffisante pour mettre à feu la matière d'allumage. L'invention concerne également des initiateurs faisant appel à cette composition énergétique, ainsi que des procédés de fabrication de la composition énergétique et d'initiateurs.
