摘要整理
碳纤维增强碳（C/C或CFC）复合材料是一类高性能材料，具有多样化的性能特征，特别适用于热学和力学高应力构件的设计。由于这类高性能材料的生产工艺成本仍然较高，需要开发经济可行的新型制造工艺。本文提出了一种创新方法，采用聚合物基拉挤成型工艺进行成型，随后通过碳化步骤制备C/C复合材料。该工艺采用碳纤维和酚醛树脂为原料，首先制备纤维体积含量为66%的单向碳纤维增强塑料（CFRP）半成品。最终获得的C/C复合材料具有良好的尺寸稳定性，弯曲强度约240 MPa，弯曲模量约135 GPa，伸长率为1.8%。该研究通过将传统拉挤成型工艺与后续碳化处理相结合，为C/C复合材料的经济化制造提供了新的思路，有望降低高性能碳碳复合材料的生产成本。
