“…The microstructural characteristics and mechanical properties of 2D, 2.5D and 3D C/C composites have been extensively studied [3][4][5][6][7][8][9]. One of the characteristics of 2D laminated C/C composites is poor inter-laminar performance that comes from lack of reinforcement in the thickness direction.…”

“…C/C composite is made up of fiber bundles and matrix, while there are a wide range of defects, such as pores and cracks in the interlayers between fiber bundles and matrix. The mechanical properties of interlayers have been investigated by Furukawa et al [3] and Hatta et al [4]. But the influence on mechanical properties of interlayers by the micro defects is neglected because they are very difficult to test and the defects cannot be observed in situ and nondestructively.…”

This article presents an investigation on the mechanical properties of porous interlayers between fiber bundles and matrix in threedimensional (3D) carbon/carbon composite. Micro computer tomography systems are employed to observe the microstructures in situ and nondestructively in the porous interlayers. Statistical analyses are utilized to obtain microstructure parameters. Mechanical models are developed to describe the mechanical behavior of these porous interlayers. Using microstructure parameters in the calculation model, mechanical properties of porous interlayers are obtained. The calculation results and experiment results by push out tests are accordant. Results show that the mechanical properties of porous interlayers are inhomogeneous and discrete.

“…Hatta and his group performed a comprehensive experimental study on 2D and 3D composites [7][8][9][10] to analyze their strength in tension, shear and compression tests. They also investigated the mechanical properties of heat-treated carbon fibers (tensile test on a single fiber) and the strength of the fiber-matrix interface (fiber bundle push-out test).…”

“…Casal et al [14] addressed the influence of porosity on the shear strength of the composite. Most of the above-mentioned publications [7][8][9][10][11][12][13][14] provide experimental observations and theoretical treatment of mechanical performance of C/C composites on micrometer level. However, they do not take into account the variation of nanostructure of pyrolytic carbon in the vicinity of fibers and its implications for strength and fracture mechanisms in C/C composites.…”

SUMMARYCarbon/carbon composites produced by chemical vapor infiltration consist of carbon fibers embedded in a matrix of pyrolytic carbon with anisotropic mechanical properties. The matrix around fibers consists of cylindrically shaped pyrolytic carbon layers of coating, which may have different textures with different mechanical properties in the axial, radial and circumferential directions. The goal of the present numerical study is to investigate the influence of the coating microstructure on stress concentrations and possible modes of failure in the carbon composite.Numerical modeling was performed on two length scales. First, the material properties of the differently textured pyrolytic carbon layers were determined on the nanometer scale using methodology based on the Eshelby theory for continuously distributed inclusions. Then, the obtained material parameters for each layer were used as input for the finite element models on the micrometer scale. The numerical simulations were conducted for three basic loading scenarios: uniaxial tension, shear loading and hydrostatic compression. The calculated stress distributions show zones of maximum stress concentrations and provide information on the possible failure regions for each material under all considered loading cases. The numerical results demonstrate good correspondence with experimentally identified failure regions.
