    • A protective garment, such as a bullet-proof vest, has multiple layers of penetration-resisting aramid fabric within an outer cover. A trauma pack is mounted on the garment to reinforce the protective action of the aramid fabric layers. The trauma pack is detachably mounted so that the garment can be used with or without the pack in position. Within the trauma pack there is a sheet of impact-absorbing plastics material, particularly a polycarbonate sheet, and this may be backed with a foamed plastics layer.
    • 防护服,如防弹背心,在外盖内具有多层耐穿透性芳族聚酰胺织物。 创伤包被安装在衣服上以增强芳族聚酰胺织物层的保护作用。 创伤包可拆卸地安装,使得衣服可以在包装或不带有位置的情况下使用。 在创伤包装中,有一片冲击吸收塑料材料,特别是聚碳酸酯片材,这可以用泡沫塑料层支撑。
