The composite material 3D wearable armor according to claim 7, characterized in that: In steps S4 and S5, a 3D modeling software is used to design and manufacture a 3D mold based on the shape and size of the human fingernail. The dimensional accuracy of the mold is controlled within ±0.1mm. Molten composite material is injected into the mold and molded under a pressure of 10-20MPa, a molding temperature of 180-220℃, and a holding time of 30-60 seconds to obtain a pre-formed wearable nail.

9. The composite material 3D wearable armor according to claim 8, characterized in that: In step S6, the mechanical energy of the initially formed wearable armor is cooled by a cooling mechanism. After cooling, the wearable armor is removed from the mold by a demolding device, and then polished by a polishing mechanism to obtain a 3D wearable armor.

10. The composite material 3D wearable armor according to claim 9, characterized in that: In step S7, the 3D wearable armor undergoes performance testing, including tests on hardness, flexibility, abrasion resistance, and color change, to ensure that its performance meets design requirements and usage standards. After passing the tests, it is packaged using moisture-proof and anti-static packaging materials to obtain the final composite material 3D wearable armor product.
