Abstract:

The precise microscopic feature of carboncarbon(C/C) composites is essential for an accurate prediction of their mechanical behavior. After fabrication, actual microscopic feature differs from simple ideal spatial model. Microcomputedtomography(CT) scan can well describe internal microstructures of composites. Therefore, a reconstructed model is developed based on mircoCT, by a series of prodcedures including extracting components, generating new binary images and establishing a finite element (FE) model. Compared with the model designed by reconstructed commercial software MIMICS, the presented reconstructed FE model is superior in terms of high mesh quality and controllable mesh quantity. The precision of the model is verified by experiment.
