“…Under such demand, integrated thermal protection materials or structures have been developed currently. [19][20][21][22] Among them, toughened uni-piece fibrous reinforced oxidation-resistant composite (TUFROC) was the representative. [23][24][25] It had a fibrous base inner material to provide heat insulation, and a treated carbonaceous cap composed of refractory oxidation-resistant ceramic carbon insulation (ROCCI) at top surface.…”

The continuous fiber reinforced porous resin‐based composites with integrated gradient fabric (CPIGF) were successfully prepared. From the bottom to the top surface, the fiber volume fraction of the integrated fabric gradually increased, as well as the fabric architecture changed, meanwhile the porosity of the resin gradually decreased. The temperature in the inner composite increased quite slowly during ablation, and the linear ablation rate ranged from 0.019 mm/s to 0.029 mm/s. The simulation results showed that the good heat insulation capacity of CPIGFs was attributed to the anisotropy properties of the fabric architecture. The microstructure analysis showed that the good ablation resistance came from both the thermal expansion of the integrated gradient fabric and the densification of the zone with 3D orthogonal woven fabric. This work is helpful for designing thermal protection materials having both heat insulation and ablation resistance for hypersonic aircrafts.

“…It usually leads to a mass increase. In addition, the existing metal lattice has limitations in thermal insulation performance and is used with additional thermal insulation materials such as ceramic fiber and aerogel [ 15 ]. It increases the manufacturing cost and process complexity, and the additional thermal insulation materials are susceptible to fracture during deformation, which is the important reason for the decline in thermal insulation performance.…”

Structurally and functionally integrated materials usually face the problem of serious functional degradation after large deformation or fracture, such as load-bearing and thermal insulation integrated lattice. In this work, the lattice with a big width-thickness ratio, which empowered the flexibility of the lattice by reducing the rod deformation during compression, was proposed. The structure of the lattice almost kept integrality after large deformation or fracture, and the decay of thermal insulation performance was less. Compared with the conventional lattice, the big width-thickness ratio lattice obtained favorable thermal insulation performance. On this basis, two kinds of flexible load-bearing and thermal insulation integrated hourglass lattices with big width-thickness ratios (BWR lattice) were prepared by SLM, and the thermal insulation and compressive performances were measured. The thermal insulation efficiency could reach 83% at 700 °C. The lattice would recover after large deformation or fracture, and the thermal insulation efficiency of the fracture lattice was 75%. This work provides a new way of designing load-bearing and thermal insulation integrated lattice and achieves the functionality preservation of load-bearing and thermal insulation integrated lattice after large deformations and fractures.

“…The TPS panel serves as a shielding cover for the fuselage of the vehicle and endures possible impact damage from debris [ 1 , 2 ]. Several types of TPS, such as metallic TPS [ 3 ], multilayer TPS [ 4 ], integrated TPS [ 5 ], and bioinspired TPS [ 6 ], have been proposed and investigated through the thermal [ 7 , 8 , 9 ] and thermo-mechanical performance [ 10 ] tests.…”

A thermal protection system (TPS) is designed and fabricated to protect a hypersonic vehicle from extreme conditions. Good condition of the TPS panels is necessary for the next flight mission. A loose bolted joint is a crucial defect in a metallic TPS panel. This study introduces an experimental method to investigate the dynamic characteristics and state of health of a metallic TPS panel through an operational modal analysis (OMA). Experimental investigations were implemented under free-free supports to account for a healthy state, the insulation effect, and fastener failures. The dynamic deformations resulted from an impulse force were measured using a non-contact three-dimensional point tracking (3DPT) method. Using changes in natural frequencies, the damping ratio, and operational deflection shapes (ODSs) due to the TPS failure, we were able to detect loose bolted joints. Moreover, we also developed an in-house program based on a modal assurance criterion (MAC) to detect the state of damage of test structures. In a damage state, such as a loose bolted joint, the stiffness of the TPS panel was reduced, which resulted in changes in the natural frequency and the damping ratio. The calculated MAC values were less than one, which pointed out possible damage in the test TPS panels. Our results also demonstrated that a combination of the 3DPT-based OMA method and the MAC achieved good robustness and sufficient accuracy in damage identification for complex aerospace structures such as TPS structures.
