“…At present, it is widely used in aircraft structures. Subsequently, the vibration characteristics of the typical connection structure of ceramic matrix composite materials and the influence of the vibration environment on the connection strength of typical components of ceramic matrix composite materials are also put on the agenda [1][2][3][4][5][6][7][8][9][10] . In this paper, the modal test, vibration test, and connection strength test are carried out for the typical connection structure of ceramic matrix composite materials, and the vibration characteristics and connection strength under a vibration environment are obtained.…”

In this paper, the typical components of ceramic matrix composites are taken as the research object, the modal test and vibration test are carried out, and the frequency and strain response of the typical components of ceramic matrix composites under random vibration load is understood. The connection strength test is carried out after the typical components of ceramic matrix composites have completed the vibration test. The influence of the vibration environment on the connection strength of typical components of ceramic matrix composites was studied.

“…Three-layered plate with C/SiC rigid-felt titanium alloy is an advanced thermal-mechanical protection structure, which shows more advantages with low density, good thermal insulation and high impact resistance. 1,2 It is no doubt that both the designing and the characterisation on C/SiC rigid-felt titanium alloy plate not only depend on the mass and velocity of the impactor but also on mechanical properties and geometry of the multilayered plate. Therefore, it is important to predict the dynamic mechanical behaviours of the C/SiC rigid-felt titanium alloy plate under impact for the design optimization and the safety evaluation.…”

In this paper, impact damage behaviours of C/SiC rigid‐felt titanium alloy three‐layered plate under normal impact are investigated. First, low velocity impact experiment of the three‐layered plate is performed by means of a drop weight impact apparatus. Second, the finite element model of the three‐layered plate is established using a damage constitutive model; also, the influences of the initial kinetic energy (the initial velocity and the mass of the impactor) on stress distributions and damage patterns of the three‐layered plate are analysed. Finally, the energy dissipation mechanisms and failure characterizations of the three‐layered plate are discussed; also, the agreements of physical variables and damage morphologies between experimental and numerical results validate the reliability of numerical simulation. The results will play an important role in designing and evaluating advanced thermal protection structure.

“…For this reason, SiCbased materials have been proposed, and widely investigated, for engineering applications in nuclear reactors, 1,2 turbine engines, 1,[3][4][5] and thermal protection systems of space vehicles. [6][7][8][9] As for other ceramic materials, the main concern with SiC materials relates to their poor fracture toughness. Nevertheless, SiC can be appreciably toughened by using ceramic fibers (e.g., carbon or SiC fibers) that allow for changing the fracture mechanism, thus increasing the fracture work by means of debonding at the fiber/matrix interface, crack bridging, and fiber pull-out.…”

Corrosion Behavior of SiC Laminate Under Decomposed Sulfuric Acid at 850°C

et al. 2012

In view of the possible application of SiC‐based ceramic laminates as critical components of hydrogen generation plants based on sulfur‐iodine or hybrid‐sulfur thermochemical cycles, the effect of corrosion on this kind of ceramics has been investigated. For this purpose, the material was exposed for 1000 h at 850°C to the corrosive action of a gaseous atmosphere simulating the environment of a sulfur‐based thermochemical hydrogen generation plant (a gaseous mixture containing several aggressive species: O2, H2O, SO2, SO3, and H2SO4, with relative concentrations representative of the inlet of an SO3 decomposer reactor). Specimens of multilayer SiC were prepared according to the following processing path: tape casting of a SiC‐based slurry, building of the green multilayer by stacking 11 sheets, final de‐binding and sintering treatments. The material microstructure and its flexural strength and modulus were studied before and after corrosion to investigate degradation phenomena. The microstructure was investigated by XRD, SEM‐EDS, XPS, and density measurements. Flexural strength and modulus were measured by four‐point bending test. The corrosive atmosphere displayed an oxidizing effect that resulted in the formation of silica, oxycarbides, and gaseous products of carbon oxidation. Nevertheless, the corrosion was hindered by the formation on the sample surface of a passivating silica layer. Bending strength and modulus were found unchanged or even improved after corrosion.
