| Abstract: | In this paper,by using impregnation carbonization technique,2D pitch based carbon carbon composites were fabricated under different pressures (0.1MPa,40MPa,80MPa and 100MPa).The densification rules of carbon carbon composites were studied.It was found that the densities of carbon carbon composites was related to impregnation carbonization cycles.And a mathematical expression on the rules was put forward.The model can be used to predict the densities of composites during fabrication process.It can also provide theoretical guide for feasibility analysis of experimental plan in fabricating carbon carbon composites. |
| Keywords: | Non metallic composites Pitch based carbon fibres Densification rules Density |
