摘要:A 3D microscopic FE approach of needle-punched carbon-carbon composite (NP C/C) is modeled based upon micro-CT technology. The images of micro-CT of NP C/C are processed and the outlines of warp, weft and punched fibre bundles are extracted. Then discrete gray images are generated and from them a microscopic FE model is reconstructed which can represent the features of micro structure and imperfections in NP C/C. Failure criterion and periodic boundary condition are employed in the FE approach and then progressive damages are investigated. Numerical simulation reveals the predominant failure mechanisms in this NP C/C under uniaxial tensile and compressive loads. The predicted stress/strain curves agree well with the experiment data.
