The invention relates to an electrically insulating composite material () comprising a polyepoxide matrix () of cycloaliphatic type or of diglycidyl ether type in a content of less than 40% by mass, from 20 to 75% by mass of one or several micrometric and/or mesometric filler(s) (), and from 0.1 to 20% by mass of at least one ionic liquid (), the masses being expressed relative to the total mass of the electrically insulating composite material (). The invention also relates to a method for manufacturing such an electrically insulating composite material (), as well as its use for an electrically insulating support () in a metal-enclosed substation ().
