Composite tail gate pedal for armored vehicle

The utility model belongs to the technical field of composite materials, and particularly relates to a tail gate pedal for an armored vehicle. The tail door pedal is of a sandwich composite structure and comprises a skin and a core layer, the skin completely wraps the core layer, and the skin is prepared from a glass fiber/aramid fiber mixed fabric reinforced resin matrix composite material; the core layer is formed by processing balsa balsa or a cross-linked PVC (Polyvinyl Chloride) foam material; grooves and through holes are formed in the upper and lower surfaces of the core layer; the grooves are mutually penetrated in the transverse direction and the longitudinal direction and are uniformly distributed; the through holes are evenly distributed in the center of the area between the transverse grooves and the longitudinal grooves. High-strength glass fiber yarns are respectively laid in the grooves and the through holes, and the high-strength glass fiber yarns penetrate through the through holes and then p
