Preparation method of ZrB2-SiC toughened B4C bulletproof sheet
The invention relates to a preparation method of a ZrB2-SiC toughened B4C bulletproof sheet, and belongs to the field of novel bulletproof armor manufacturing. The bulletproof sheet is obtained by the following method: firstly, selecting ZrSi2, B4C and C as raw materials, taking and mixing the raw materials according to a molar ratio of 2: 1: 3, then mixing the mixed powder and B4C powder according to a volume ratio of 1: 9, 1.5: 8.5, 2: 8, 2.5: 7.5 and 3: 7, then sequentially carrying out wet ball milling, drying by a rotary evaporator and screening by a screen on the mixed powder, and finally sintering the powder in a hot pressing furnace to obtain the bulletproof sheet. The B4C-ZrB2-SiC bulletproof sheet composite material is prepared by regulating and controlling the raw material ratio and a sintering process. The B4C-ZrB2-SiC bulletproof sheet composite material prepared by the method is uniform in phase distribution, and has the advantages of high fracture toughness, high strength and the like.
本发明涉及一种ZrB2‑SiC增韧B4C防弹片的制备方法，属于新型防弹装甲制造领域。该防弹片由以下方法获得：首先选取ZrSi2、B4C和C作为原料，按照摩尔比2:1:3取料混合，然后将上述混合粉体与B4C粉按照体积比1:9、1.5:8.5、2:8、2.5:7.5、3:7混合，随后将混合粉体依次经湿法球磨，旋转蒸发仪干燥，筛网过筛，最后在热压炉中对粉体进行烧结，通过调控原料配比以及烧结工艺，制备获得B4C‑ZrB2‑SiC防弹片复合材料。采用该方法制备的B4C‑ZrB2‑SiC防弹片复合材料各相分布均匀，具有断裂韧性强，强度高等优点。
