Multilayer continuous fiber reinforced fused quartz ceramic composite material and preparation method thereof
The invention discloses a multilayer continuous fiber reinforced fused quartz ceramic composite material and a preparation method thereof, and the method comprises the following steps: firstly immersing woven carbon fibers into a precursor solution in which boric acid is dissolved in pure methanol, introducing ammonia gas into the boronized woven carbon fibers under a nitrogen condition, and heating to obtain boron nitride modified woven carbon fibers; the method comprises the following steps: dispersing fused quartz particles in water, adding a dispersing agent ammonium citrate, and adjusting the pH value to obtain a fused quartz suspension; and compounding the boron nitride modified woven carbon fiber and quartz woven fiber cloth in a layered manner, immersing the compounded carbon fiber and quartz woven fiber cloth into a fused quartz suspension under high pressure, carrying out multiple cycles to obtain a compact composite material biscuit, and finally sintering to obtain the multilayer continuous fiber composite reinforced fused quartz ceramic. As an integral structure, the composite material disclosed by the invention is relatively good in mechanical property, especially high-temperature mechanical property and dielectric property, relatively high in density and good in impact resistance. Moreover, the method is simple in process, low in cost and suitable for industrial production.
本发明公开了一种多层连续纤维增强熔融石英陶瓷复合材料及其制备方法，该方法包括以下步骤：首先将编织碳纤维浸入到硼酸溶于纯甲醇的前驱体溶液中，将硼化的编织碳纤维在氮气条件下引入氨气加热，获得氮化硼改性编织碳纤维；将熔融石英颗粒分散在水中，加入分散剂柠檬酸铵，调节pH值获得熔融石英悬浮体；再将氮化硼改性编织碳纤维与石英编织纤维布分层复合后，在高压下浸入熔融石英悬浮体中，经过多次循环后获得致密复合材料素坯，最后烧结得到多层连续纤维复合增强熔融石英陶瓷。本发明得到的复合材料作为一个整体结构，其力学性能尤其高温力学性能和介电性能较好，密度较高，耐冲击性能良好。而且，本发明工艺简单，成本低，适合工业化生产。
