Electroplated copper was used as the substrate and the microstructure and crystal structure of the material were analyzed by scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD).The results show that the mixing ratio of C3H6-C2H2 gas has a significant effect on the morphology and microstructure of the composite material. With increasing C2H2 concentration, the carbide layer on the surface of the substrate becomes thicker and the carbide grain size becomes larger. In addition, increasing C2H2 concentration can also increase the carbon content of the composite material. Compared with a single carbon source, a mixed carbon source can significantly improve the rotational torque and deformation modulus of the composite material.精品文档---下载后可任意编辑Therefore, this study shows that the carbonization degree and performance of composite materials during the preparation process can be controlled by adjusting the mixing ratio of C3H6-C2H2 gas, which provides important theoretical guidance for the development of high-performance carbon-based composite materials.Keywords: CVI, composite material, C3H6-C2H2 mixed gas, carbide, deformation modulus
