The invention concerns a fragment- and bullet-proof helmet comprising a carcass consisting of at least one resin-free layer enclosed between at least two resin-containing layers, wherein the resin-containing layers are connected to each other by the edges of the carcass over its entire contour, such that the resin-free layer is encapsulated hermetically between the resin-containing layers, forming a plurality of layers which improves rigidity and ballistic resistance. |
