A method for manufacturing a high performance thermoplastic matrix composite ballistic helmet includes forming/shaping highly consolidated helmet preforms free of wrinkles and with no cuts or seams from a flat stack of 0/90 uni-directional prepreg layers, both with and without carbon epoxy skins or layers, using a pressure forming process. The wrinkle free and no cuts pre-formed helmet shell is pre-heated and placed between match-metal dies in a compression molding press to be molded under constant pressure during heating at high temperature and cooling down to below 160 F. in less than 45 minutes.

A system for forming a deep drawn helmet and method therefor are disclosed. The system includes a forming draw ring and a non-forming draw ring and supports a prepreg stack between a forming aperture of the forming draw ring and a non-forming aperture of the non-forming draw ring. The system clamps a flange portion of the prepreg stack between a contact surface of the forming draw ring and a contact surface of the non-forming draw ring, which forms a clamped assembly of the rings and the prepreg stack. The system then forms a deep drawn helmet preform from the prepreg stack of the clamped assembly. The same system or a different forming system then consolidates one or more of the preforms into a final deep drawn helmet. The system can control sliding of the flange during forming of the helmet preform without reducing the flange clamping force.

Manufacturing method of a body protection and resulting body protection, wherein the method comprises producing a structural shell (10) with a maximum thickness of 5 mm, made of thermoplastic material, and defining a concave interior (11) and a convex exterior (12); over-moulding an expanded polystyrene layer (20) overlapping the concave interior (11) of the structural shell (10), producing its adhesion by close contact to the structural shell (10); and wherein the structural shell (10) is produced by means of the distributed placement, in a mould, of a mixture of thermoplastic material and of reinforcing fibres stable at temperatures equal to or lower than the melting temperature of the thermoplastic material, the closure and heating of the mould causing the melting of the thermoplastic material without damaging the reinforcing fibres, and the subsequent cooling of the mould, hardening the thermoplastic material with the reinforcing fibres embedded therein.
