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.

A preform charge is formed by forming an assemblage of preforms, wherein preforms in the assemblage are bonded to a neighboring preform such that the preform charge effectively becomes a single unit. The preform charge can then be added to a mold to fabricate a part via compression molding.

A sabot petal is described herein comprising a plurality of woven axial and undulated fibers angled to transfer setback loads. In some cases, the petal is a one-piece component configured to be positioned around a long rod projectile or other aerostructures or aeroshell shapes to be launched with in a gun bore, or rocket or missile launch tube. Corresponding systems and methods are also disclosed.

Provided is a fiber-reinforced resin molded body that has continuous voids and includes a carbon fiber nonwoven fabric and a thermosetting resin, in which the continuous voids have a porosity of 50% by volume to 97% by volume, and contact points of discontinuous carbon fibers constituting the carbon fiber nonwoven fabric are immobilized by the thermosetting resin having a substantially spherical shape of 40 m to 300 m in diameter. Also provided is a method of producing a fiber-reinforced resin molded body, the method including the following steps in the order mentioned: the preform forming step of forming a preform including a carbon fiber nonwoven fabric in a molding die; the injection preparation step of forming a closed space in which the preform is arranged; the injection step of injecting a liquid thermosetting resin into the closed space; the porosity adjustment step of allowing the carbon fiber nonwoven fabric to expand in the thickness direction; and the curing step of maintaining the preform at a temperature equal to or higher than a curing temperature of the thermosetting resin. According to this method, a fiber-reinforced resin molded body that includes a carbon fiber nonwoven fabric and a thermosetting resin is simply produced.

Proposed is a 3D over-printing device for over-printing a 3D shape on an existing structure, the device including: a vat containing a light-curable material; a driving part configured to fix the existing structure and move the existing structure vertically, layer by layer, within the vat; and an optical part comprising a projector and a mirror structure, and configured to photocure an area to be cured on a surface of the light-curable material by projecting UV light in several directions simultaneously from above the surface of the light-curable material toward the surface of the light-curable material that is upward exposed and in contact with the existing structure.
