A method for producing a high dimensional precision composite element using ionization polymerization and an element made by such method. The element includes a support panel flanked on at least one side with a skin fixed by an adhesive resin and including at least one lap of organic or mineral fibers and an organic linking matrix. The method includes placing at least one lap of fibers preimpregnated with an ionization polymerizable resin on a mold to form the skin, the mold having a predetermined shape and dimensions for the element to be produced; placing a film of an ionization polymerizable adhesive resin on the skin; placing the support panel on the film to form a skin/film/panel unit, the support panel having a predetermined thickness; compacting the skin/film/panel unit; and polymerizing the polymerizable resins during the compacting by subjecting the skin/film/panel unit to ionization.
