“…If matrix cracking and interface debonding are present upon first loading, stress-strain hysteresis loops will develop as a result of energy dissipation through frictional sliding between the fiber and matrix during unloading and subsequent reloading [4,6,7,[11][12][13][14][15][16][17][18][19][20][21]. The shape, size and location of the hysteresis loops depend on the interface debonding and slipping.…”

An approach to estimate interface shear stress of ceramic matrix composites during fatigue loading has been developed in this paper. By adopting a shear-lag model which includes the matrix shear deformation in the bonded region and friction in the debonded region, the matrix crack space and interface debonding length are obtained by matrix statistical cracking model and fracture mechanics interface debonding criterion. Based on the damage mechanisms of fiber sliding relative to matrix in the interface debonded region upon unloading and subsequent reloading, the unloading counter slip length and reloading new slip length are determined by the fracture mechanics method. The hysteresis loops of four different cases have been derived. The hysteresis loss energy for the strain energy lost per volume during corresponding cycle is formulated in terms of interface shear stress. By comparing the experimental hysteresis loss energy with computational values, the interface shear stress corresponding to different cycles can then be derived. The theoretical results have been compared with experimental data of three different ceramic composites.

“…Mei et al [9] investigated the loading/unloading tensile behavior of the 2d-C/SiC ceramic matrix composites at room temperatrue. The stress interval was about 20 MPa, i.e., the peak stress value in a loading/unloading cycle is about 20 MPa higher than that in the preceding loading/unloading cycles.…”

An approach to estimate the fiber/matrix interface shear stress of woven ceramic matrix composites during fatigue loading has been developed in this paper. Based on the analysis of the microstructure, the woven ceramic matrix composites were divided into four elements of 0 o warp yarns, 90 o weft yarns, matrix outside of the yarns and the open porosity. When matrix cracking and fiber/matrix interface debonding occur upon first loading to the peak stress, it is assumed that fiber slipping relative to matrix in the interface debonded region of the 0 o warp yarns is the mainly reason for the occurrence of the hysteresis loops of woven ceramic matrix composiets during unloading and subsequent reloading. The unloading interface reverse slip length and reloading interface new slip length are determined by the interface slip mechanisms. The hysteresis loops of three different cases have been derived. The hysteresis loss energy for the strain energy lost per volume during corresponding cycle is formulated in terms of the fiber/matrix interface shear stress. By comparing the experimental hysteresis loss energy with the computational values, the fiber/matrix interface shear stress of woven ceramic matrix composites corresponding to different cycles can then be derived. The theoretical results have been compared with experimental data of two different woven ceramic composites.

“…[76][77][78][79][80][81][82] The fiber volume of 2D composites and 3DN composites were 40 and 32 vol%, respectively. The higher fiber volume was beneficial to the improvement of mechanical properties, but just the difference of fiber volume could not lead to the obvious difference between 2D C/SiC and 3DN C/C-SiC.…”

Carbon fiber reinforced ceramic matrix composites (CFCCs) are promising materials for hightemperature applications. Due to the unique nanolaminated structure and special properties, the MAX phases are promising reinforcements for CFCCs. As one representative member of the MAX phases, Ti 3 SiC 2 has been in situ formed in C/C-SiC and C/SiC composites by a joint process of slurry infiltration and liquid silicon infiltration in recent years. The composites containing Ti 3 SiC 2 exhibited improved mechanical properties, tribological performance, and ablation behavior compared with those of unmodified composites. The introduction of MAX phases in CFCCs could extend their application fields effectively, and it is expected to bring more benefits to CFCCs by introducing the MAX phases in the future.
