Graphene modified silicon carbide ceramic material, preparation method thereof and bulletproof armor
The invention discloses a graphene modified silicon carbide ceramic material, which comprises graphene, alpha-phase silicon carbide and beta-phase silicon carbide, wherein the mass percentage of the graphene in the graphene modified silicon carbide ceramic material is 0.5%-1%. The invention also discloses a preparation method of the graphene modified silicon carbide ceramic material. The preparation method comprises the following steps of: mixing graphene, alpha-phase silicon carbide, a three-dimensional carbon material, alcohol-soluble resin and a solvent to obtain pasty mixed powder; granulating the mixed powder to obtain pre-granules; pressing the pre-particles into a biscuit; and making liquid metal silicon to be infiltrated into the biscuit and sintering at the sintering temperature of 1,450 DEG C to 1,600 DEG C, and the heat preservation time at the sintering temperature ranges from 1.5 h to 2.5 h. The invention further discloses the bulletproof armor.
本发明公开了一种石墨烯改性碳化硅陶瓷材料，包括石墨烯、α相碳化硅和β相碳化硅，其中，所述石墨烯在所述石墨烯改性碳化硅陶瓷材料中的质量百分数为0.5%~1%。本发明还公开了一种石墨烯改性碳化硅陶瓷材料的制备方法，包括以下步骤：将石墨烯、α相碳化硅、三维碳材料、醇溶性树脂及溶剂混合得到糊状的混合粉料；将所述混合粉料造粒得到预颗粒；将所述预颗粒压制成素坯；将液态金属硅渗入所述素坯中并进行烧结，烧结温度为1450℃~1600℃，在所述烧结温度保温时间为1.5 h~2.5h。本发明还公开了一种防弹装甲。
