Abstract
Needle-punched carbon/carbon composite is widely used in re-entry aerospace projects and braking system, for the favorable mechanical properties at high temperature. In this study, a mesoscale mechanical model was investigated, in which a proposed circular arc beam element was embedded into solid element, and the displacements of beam element simulated for fiber bundles were solved through displacements of solid element modeled for matrix. Uniaxial tension properties and progressive damages of this composite were predicted, then the simulated model was verified by experiment.
