Woven carbon fibers reinforced Al-matrix composites were successfully prepared through a liquid metallurgy process in pulsed magnet field (PMF). Various wetting conditions and PMF application methods were respectively adopted to reveal the infiltration mechanism, based on which a model and hypothesis of the electromagnetic infiltration were developed. There was an exact match between the metallization depth in electroless plating process and the infiltrating depth in spontaneous infiltrating process, and an obvious improvement in the infiltration result was obtained with the introduction of PMF. The finite-element simulation result indicated that the molten matrix in PMF could offer periodic squeeze and impact effects on the fibers. With the application of PMF, the bending strength of the obtained composite improved from 112 to 203 MPa. Furthermore, the electromagnetic infiltration morphology in PMF possessed the gradient and synchronization characteristics, which was different from the spontaneous infiltration morphology with a step-by-step characteristic.

在脉冲磁场（PMF）中，通过液态冶金工艺成功地制备了碳纤维增强的铝基复合材料。分别采用多种润湿条件和PMF施加方法揭示其渗透机理，在此基础上建立了电磁渗透的模型和假设。化学镀过程中的金属化深度与自发渗透过程中的渗透深度之间存在精确匹配，而引入PMF可以使渗透结果得到明显改善。有限元模拟结果表明，PMF中的熔融基体可以对纤维提供周期性的挤压和冲击作用。随着PMF的应用，所得复合材料的弯曲强度从112MPa提高至203MPa。
