Pore-throat structure characterization of carbon fiber reinforced resin matrix composites: Employing Micro-CT and Avizo technique.

Micro-CT technique poses significant applications in characterizing the microstructure of materials. Based on the CT three-dimensional(3D) reconstruction technology and "Avizo" 3D visualization software, the microscopic pore-throat structure of porous media can be quantitatively characteri...
