| titleOfInvention | Large-size special-shaped carbon-based composite material component and preparation method thereof |
| abstract | The invention relates to a large-size special-shaped carbon-based composite material component and a preparation method thereof. The component comprises the following components in percentage by mass: 20-35% of carbon fiber, 35-75% of pyrolytic carbon and 5-15% of SiC. The preparation method comprises the following steps: according to the required part shape, firstly needling the continuous carbon fiber to obtain the carbon fiber with the density of 0.4-0.55 g/cm 3 The preform of (a); fixing the inner and outer surfaces of the prefabricated blank by using a graphite mold; and then sequentially carrying out high-temperature heat treatment, first carbon deposition, mould unloading, rough machining, second carbon deposition, graphite treatment, silicon steam bath and finish machining to obtain a finished product. The invention solves the problems that large-size special-shaped carbon-based composite material components are easy to deform after standing for a long time and in the preparation process, and the obtained product has the advantages of good mechanical property, low thermal expansion coefficient, high thermal conductivity, good chemical stability and the like, is convenient for industrial production, and can be applied to the fields of aerospace, transportation, biomedical use and the like. |
