Method for improving tensile property of quartz fiber reinforced silicon dioxide composite material
The invention relates to a method for improving the tensile property of a quartz fiber reinforced silicon dioxide composite material, which takes a quartz fiber preform as a reinforcing phase and silicon dioxide as a matrix, and is used for preparing the quartz fiber preform reinforced silicon dioxide composite material by the following steps: firstly, weaving quartz fibers into a preform according to a certain weaving structure; the preparation method comprises the following steps: firstly, carrying out primary vacuum/pressure impregnation on a preform, then pretreating the preform, removing an impregnating compound on the surface of the preform, then clamping the preform by using a clamping plate during primary vacuum/pressure impregnation, and then completing molding of a composite material blank through circulation of multiple cycles of vacuum/pressure impregnation, drying, sintering and other working procedures. The method is simple in step and obvious in effect, and the quartz fiber reinforced silicon dioxide composite material with relatively high tensile property can be obtained by tightening the space between the clamping plates.
本发明涉及一种提高石英纤维增强二氧化硅复合材料拉伸性能的方法，该方法以石英纤维预制体为增强相，二氧化硅为基体，通过以下步骤制备石英纤维预制体增强二氧化硅复合材料：首先将石英纤维按一定的编织结构编织成预制体，然后对预制体进行预处理，去除预制体表面的浸润剂，接着在第一次真空/压力浸渍时使用夹板将预制体夹紧，再通过多个周期的真空/压力浸渍、干燥、烧结等工序的循环，完成复合材料坯体的成型。该方法步骤简单、效果明显，通过收紧夹板间距，可以得到拉伸性能较高的石英纤维增强二氧化硅复合材料。
