Phenolic resin-silicon powder slurry and preparation method thereof
The invention discloses phenolic resin silicon powder slurry and a preparation method thereof. The phenolic resin silicon powder slurry comprises the following components in percentage by weight: 22 to 24 percent of phenolic resin, 63 to 66 percent of silicon powder, 4 to 6 percent of methanol and 5 to 8 percent of benzenesulfonic acid. The phenolic resin silicon powder slurry is used for preparing a C/CSiC composite material, the phenolic resin silicon powder slurry can be put into a directional hole channel prepared in a carbon fiber preform, carbon in phenolic resin can be mixed with silicon powder in advance, and pyrolytic carbon formed by introducing C3H8 gas for pyrolytic deposition is mixed with the silicon powder for densification treatment, so that the C/CSiC composite material isprepared. Two kinds of carbon with different sources and components are fully mixed with silicon to react, and a SiC matrix with higher compactness can be generated, so that the comprehensive mechanical property of the C/CSiC composite material is greatly improved.
本发明公开了一种酚醛树脂‑硅粉浆料及其制备方法，所述酚醛树脂‑硅粉浆料包括如下重量百分比的组分：酚醛树脂22wt％～24wt％、硅粉63wt％～66wt％、甲醇4wt％～6wt％、苯磺酸5wt％～8wt％。上述的酚醛树脂‑硅粉浆料用于制备C/C‑SiC复合材料，酚醛树脂‑硅粉浆料会放入碳纤维预制体上制备定向孔通道中，酚醛树脂中的碳会预先与硅粉混合，致密化处理通入C3H8气体热解沉积形成的热解炭与硅粉混合，两种不同来源、成分的碳充分与硅混合发生反应，可以产生出更高致密性的Sic基体，从而大大改善C/C‑SiC复合材料的综合力学性能。
