提出了一种制备液态金属浸渗用短碳纤维预制体的新方法。预成型件通过湿法成型成形并通过热解碳（PyC）强化。在1600 °C下，通过SiO与PyC的反应在碳纤维上制备了SiC涂层。X射线衍射，扫描电子显微镜，和能量色散X射线光谱法被应用在预制件的表征。通过气压浸渗实验验证了液态金属浸渗预制件的可行性。微观结构分析表明，碳纤维均匀分布在预制体中，纤维表面包覆有内层PyC和外层SiC。浸渗实验证明，所制备的预制件在较低的浸渗压力和温度下进行液态金属浸渗是可行的。
A novel method of fabricating short carbon fiber preforms was proposed for liquid metal infiltration. The preforms were shaped by wet forming and strengthened by pyrocarbon (PyC). SiC layers were prepared on carbon fibers by the reaction of SiO and PyC at 1600 °C. X-ray Diffraction, Scanning Electron Microscopy, and Energy Dispersive X-ray Spectroscopy were applied in the characterization of the preforms. Gas pressure infiltration was done to demonstrate the feasibility of the preforms for the liquid metal infiltration. The microstructure analysis indicates that carbon fibers are uniformly distributed in the preforms, and fibers are coated with an inner layer of PyC and an outer layer of SiC. The infiltration experiment proves that the prepared preforms are feasible for liquid metal infiltration under low infiltration pressure and temperature.
