Abstract (en)
[origin: EP2316291A1] The shell has an armor provided with parts that are impregnated in epoxy type resin matrix (R) having additive i.e. Nanostrength(RTM: acrylic block copolymer based additive), to enhance mechanical resistance of the shell. The parts correspond to most delicate areas of a human head. Other parts of the armor are impregnated in resin matrix that does not have additive. An independent claim is also included for a method for realizing a helmet shell.
