工程陶瓷和凯夫拉纤维增强塑料（KFRP）都是难以切割的，陶瓷/KFRP双板复合装甲也是如此。本文在通用钻床上进行了陶瓷/KFRP双板复合装甲的专用烧结金刚石钻芯钻削实验研究。在钻孔实验的基础上，讨论了加工方式、钻孔顺序和加工效率。根据所讨论的实验结果，采用手动步进加工，先对KFRP背板进行钻孔，并选择合理的工艺参数，可以极大地促进陶瓷/KFRP双层复合装甲的钻孔。结果表明，本文提出的加工方法适用于小批量生产。
Both engineering ceramics and Kevlar fiber reinforced plastics (KFRPs) are difficult to cut, so is the ceramics/KFRP double-plate composite armor. In this work, an experimental study of drilling the ceramics/KFRP double-plate composite armor by using a special sintering diamond core drill has been carried out on a general-purpose drilling machine. Machining mode, drilling sequence, and machining efficiency have been discussed based on drilling experiments. According to the discussed experimental results, machining using manual step feed, drilling the KFRP backboard firstly, and selecting the reasonable technical parameters could greatly facilitate the hole drilling in the ceramics/KFRP double-plate composite armor. The results achieved show that the machining method presented in this work is applicable for small order production.
