Abstract An impression is firstly taken of the skull, which makes it possible to produce a replica thereof. On the latter are successively deposited a thermostable film, a first carbon fabric layer, a second aramide layer and a third carbon fabric layer. These three layers form the protective skull cap following polymerization in an oven and elimination of the skull replica and the thermostable film. The skull cap can optionally contain holes. A protective skull cap for at least partly covering a skull, where the cap is worn directly on the skin and is flexible to perfectly adapt to the shape of the skull so as to be in intimate contact therewith at all points. The skull cap consists of three layers, from the inside to the outside, a first carbon fabric layer, a second [ARAMIDE] polyarylamide fiber fabric layer and a third carbon fabric layer. These layers are impregnated with a high elongation resin so that the thickness of the cap is equal to or less than 1 mm.
A protective skull cap for at least partly covering a skull, said cap being worn directly on the skin and being flexible to perfectly adapt to the shape of the skull so as to be in close contact therewith at all points, said skull cap consisting of three layers, from the inside to the outside, a first carbon fabric layer, a second polyarylamide fiber fabric layer and a third carbon fabric layer, the layers being impregnated with a high elongation resin and the thickness of the cap being equal to or less than 1 mm.
