背景技术
导弹部队的野外作战训练和野外测试是常规且必须的训练项目，在训练过程中需要对指定区域的人员、设备及相关物资进行安全防护。传统的板材防护材料有钢板、砂土、混泥土等等，但单一材料在使用性上均有不同程度的“短板”。例如：钢板的耐热但不耐火，耐腐蚀性较差；砂土抗高强***冲击所需要的量过大，难以快速形成防爆能力；混凝土施工周期长，不便于拆卸和运输，此外，破片和冲击波产生的冲击可能形成碎块，对附近区域产生二次伤害。
本发明的复合防爆板材结合传统防爆材料的优点，并引入先进复合材料作为复合材料板材的主承载层，在提高板材强度和韧性的前提下大大降低了板材的重量。同时具有耐腐蚀，轻质高强，防破片，抗冲击，无碎片，适用范围广，安装简易等特点。

破片毁伤层、缓冲分散层以及结构支撑层厚度比例为1：2～4：7～5。
一种抵抗高速破片与高强度***冲击的复合防爆板的制造方法，其特征在于，包括下列步骤，
第一步，将高强结构钢通过刨床，单面加工出破片毁伤的尖角结构；
第二步，将超高分子聚乙烯进行表面磨砂处理；
第三步，按照设计的编织方式进行高强玻璃纤维织物的编织；
第四步，将编织好的织物放入环氧树脂中，制作成预浸布；

第六步，铺贴结构支撑层并热压成型；成型温度160℃，成型压力45MPa，升温及固化时间6h；
第七步，用环氧粘接剂对破片毁伤层、缓冲分散层以及结构支撑层进行粘接。
本发明结构简单，造价低，制作方便，抵抗高速破片与高强度***冲击性能强，是很好的防暴材料。
