Abstract
The utility model discloses a bulletproof panel of a quilting structure. The bulletproof panel is formed in a hot pressing mode and comprises multiple sets of UD composite materials which are arranged in a laminated mode. Every two adjacent sets of UD composite materials are connected through quilting threads. Each set of UD composite materials is composed of the multiple layers of UD sheets in a laminated mode, and the layers of UD sheets are connected through the quilting threads in a sewn mode. Each layer of UD sheets comprises multiple layers of pre-impregnation pieces of which fibers are arrayed in parallel in the single direction. The UD composite materials are sewn into a whole through quilting threads, so that when the bulletproof panel is shot by multiple bullets, the quilting threads effectively reduce or stop action force, on interlamination of the bulletproof plate, of the quilting threads; when the bulletproof panel is impacted by the bullets, sheet layers in the bulletproof panel will not be prone to scatter due to the dragging of the quilting threads, the defect that an existing bulletproof panel is prone to interlamination separation is overcome, the capacity for bearing impact of the bullets is improved for the bulletproof plate, and therefore overall bulletproof performance of the bulletproof panel is improved.
