Preparation method of composite fiber reinforced boron carbide ceramic plate
The invention discloses a preparation method of a composite fiber reinforced boron carbide ceramic plate. The preparation method comprises the steps: weighing the components: weighing boron carbide powder, carbon fiber powder and beta silicon carbide whiskers in parts by mass; mixed preparation: serving the weighed boron carbide powder as a base material, serving the weighed carbon fiber powder and beta silicon carbide whiskers as auxiliary materials, and stirring and mixing by ultrasonic stirring equipment with the mixing time of 3 min-5 min, to obtain a mixture; sintering a ceramic plate; and weighing 3 kg of the mixture, placing in a vacuum hot-pressing sintering furnace mold, setting the process temperature to be 2000 DEG C, setting the pressure intensity to be 250 MPa, carrying out material sintering, after sintering is completed, taking the material out to be cooled when the temperature reaches 200 DEG C or below, demolding after cooling is completed, and thus obtaining the ceramic plate. Boron carbide powder is used as a base material, carbon fiber powder and beta silicon carbide whiskers are used as auxiliary materials, and the composite fiber reinforced boron carbide ceramic plate is added, so that the prepared ceramic plate has ultrahigh hardness and excellent toughness.
一种复合纤维增强碳化硼陶瓷板制备方法，称量各个组分：碳化硼粉末、碳纤维粉、β碳化硅晶须按照所述质量份数进行称量；混合制备：将称量好的碳化硼粉末作为基材，称量好的碳纤维粉和β碳化硅晶须作为辅材，使用超声波搅拌设备进行搅拌混合，混合时间为3～5min，得到混合料；陶瓷板烧结；称取3kg混合料，置于真空热压烧结炉模具中，设置工艺温度为2000℃，压强设置为250Mpa进行材料烧结，烧结完成后，温度到达200℃以下即可取出材料进行冷却，冷却完成后脱模即可得到陶瓷板。本发明采用碳化硼粉末作为基材，碳纤维粉和β碳化硅晶须作为辅材，采用复合嫌恶增加碳化硼陶瓷板，制得但是陶瓷板具有超高硬度的同时，其韧性极佳。
