对于装甲车辆来说,应通盘考虑生存力、机动性和承载能力等各种竞争性需求。提高生存力需求体现在“洋葱式生存力”的每一层防护中,这推动了采用复合材料的轻型车辆的发展。一般来说,超高硬度钢、轻质高分子化合物和陶瓷等装甲材料,层层叠附于金属车体,这种材料虽可以提高乘员防护力,但会减少车辆有效载荷,降低机动性, For armored vehicles, all competing demands such as viability, mobility and carrying capacity should be considered in their entirety. The need to increase viability is reflected in every layer of ’onion-based viability’ that drives the development of lightweight vehicles that use composite materials. In general, armor materials such as ultra-high hardness steel, light-weight polymer compounds and ceramics are laminated on a metal body, which can improve occupant protection but reduce vehicle payload and mobility,
