A composite material that includes a layer of reinforcing fibres impregnated with a curable resin matrix and a plurality of electrically conductive composite particles positioned adjacent or in proximity to the reinforcing fibres. Each of the electrically conductive composite particles is composed of a conductive component and a polymeric component, wherein the polymeric component includes one or more polymers that are initially in a solid phase and are substantially insoluble in the curable resin, but is able to undergo at least partial phase transition to a fluid phase during a curing cycle of the composite material. Un material compuesto que incluye un capa de fibras de refuerzo impregnadas con una matriz de resina curable y múltiples partículas compuestas eléctricamente conductoras colocadas adyacentes o cerca de las fibras de refuerzo. Cada una de las partículas compuestas eléctricamente conductoras está compuesta de un componente conductor y un componente polimérico, en donde el componente polimérico incluye uno o más polímeros que se encuentran inicialmente en una fase sólida y son sustancialmente insolubles en la resma curable, pero puede experimentar una transición de fase al menos parcial a una fase fluida durante un ciclo de curado del material compuesto.
