An exemplary method of manufacturing a polymer matrix composite electromagnetic shielding structure includes pretreating a dry fiber reinforcement with a composition including a carrier and a conductive element, laying out the pretreated reinforcement to form a pre-form structure, applying a resin to the pre-form structure, and curing the resin at room temperature. Another exemplary method of manufacturing a polymer matrix composite electromagnetic shielding structure includes laying out a plurality of dry fiber reinforcements, placing at least one ply between any two of the plurality of dry fiber reinforcements, the ply having a non-woven including a conductive material, applying a resin to the plurality of dry fiber reinforcements and the at least one ply, and curing the resin.
