Definitions

  • the present invention relates to a ceramic guard plate, and more particular to a bendable ceramic guard plate that can provide effective protection.
  • a bulletproof cloth mainly comprises sequentially adhered cladding layer, ceramic plate, and barrier layer.
  • the aforementioned cladding layer is a bulletproof fiber sheet
  • the ceramic plate is formed of plural butted ceramic plates
  • the barrier layer is formed of plural adhered laminated bulletproof fiber sheets.

  • Each of the second and third ceramic plates comprises at least one symmetric pair of a first lateral face and a second lateral face, and each of the first side and the second lateral faces of the second and third ceramic plates is an inclined plane extending outwardly and upwardly from a bottom side of the second and third ceramic plates, respectively. And an adhesive is deformably adhered between the first side of the first ceramic plate and the second lateral face of the third ceramic plate and between the second side of the first ceramic plate and the first lateral face of the second ceramic plate.
