“…The main reason is that the volume content of axial fiber rod and radial fiber bundle in RVE decreases while the volume fraction of matrix increases with the increase of braiding distance. Since the modulus and CTE of the matrix are lower than that of the fiber rod and fiber bundle, the increase of the volume fraction will inevitably lead to the overall decrease of the modulus and CTE [ 28 , 29 , 30 , 31 , 32 , 33 ].…”

“…The pores and cracks in the matrix and interface of the axial braided C/C composite were regarded as inclusions with different shapes and sizes and introduced into the pure carbon matrix. In this paper, the random geometric models meeting objective distribution law of microstructure characteristics were generated by a subroutine coded by python and its mechanical properties were calculated by FEM, which can consider the interaction between various microstructures [28][29][30][31][32].…”

It is well established that the microstructure has significant effects on the properties of axial braided C/C composites. In this study, a method coupling the homogenization method and finite element method (FEM) was proposed to predict the relationship between the microstructure characteristics and macroscopic properties. Based on the representative volume element (RVE) model, the periodic displacement boundary condition was introduced to predict the equivalent elastic properties of the RVE and component of C/C composite material, and the coefficient of thermal expansion (CTE) of the material was predicted by the energy prediction method. The predicted results were in good agreement with experimental results. By predicting the thermal and mechanical properties of the materials with different braiding spacing and fiber rod diameter, the variation of the properties with braiding spacing and fiber rod diameter was obtained. The research methods and results in this paper could provide important references for the optimization and rational application of composite materials.

“…However, the surface of the new aircraft will cause serious aerodynamic heating problems due to the shock wave and viscous effect during the reentry process. Under the coupling effect of high temperature and complex aerodynamic loads, the probability of failure of TPS covering the surface of the aircraft is much higher than that of general structures [3][4] . Once the TPS is destroyed and high thermal airflow enters the interior of the aircraft, it is possible to cause the overall failure of the reusable launch vehicle during the reentry process.…”

Thermal protection structures (TPS) are the key component in the design and manufacture of the reusable launch vehicle. The probability of failure of TPS in an aerodynamic thermal environment during reentry is much higher than that of ordinary structures. There is an urgent need to develop a structural health monitoring (SHM) method that can achieve rapid diagnostic for TPS to realize the high reliability and maintainability of the reusable launch vehicle. Hence, this paper aims at the typical TPS made of C/C composite material, the feasibility of SHM methods based on the active piezoelectric guided wave was studied and verified. And the propagation characteristics of guided wave in the TPS such as the multi-mode, the signal frequencies of monitoring and the effects of material anisotropy on the propagation characteristics of the guided wave were analyzed. Then, a guided wave monitoring experiment of C/C TPS with simulation damage was carried out, and the variation of a guided wave under different damage levels was analyzed from the aspects of amplitude, phase, damage scattering and damage index. The results show that the SHM methods based on active piezoelectric guided wave can effectively monitor the damage and damage expansion on the surface of C/C TPS.
