Summary: SiCf/SiC composites have potential applications in aerospace for high-temperature structural components. Understanding their mechanical properties and failure behaviors at ultra-high temperatures is crucial. This study conducted tests and fracture surface analysis, revealing that the in-plane compressive and interlaminar shear strengths of SiCf/SiC composites increase with temperature, while the flexural strength decreases.

Summary: This study compares the mechanical behavior differences between simplified first wall models and fully integrated first wall/blanket models, providing reference for conceptual design and optimization of the first wall. It is found that a one quarter first wall model with reasonable constraints is closer to the results of the fully integrated FW/blanket model.

Summary: The study investigated the microstructure, failure behavior, and interfacial properties of SiCf/BN/SiC and C-f/PyC/SiC composites using the fiber push-in test. The findings showed differences in the mechanical response of the interfacial domain, with SiCf/BN/SiC experiencing interface debonding accompanied by interphase fracture, while C-f/PyC/SiC exhibited interface debonding along with interphase lateral slipping without any interphase fracture. The calculated interfacial shear stress indicated that C-f/PyC/SiC had a weaker interfacial domain compared to SiCf/BN/SiC.

Summary: This research investigated the fatigue resistance and damage mechanisms of 2D woven SiC/SiC composites at high temperatures. Fatigue tests were conducted at 1200°C and 1000°C with maximum stresses ranging from 80 to 120 MPa. The results showed that the cycle lifetimes of the composites decreased sharply with increasing maximum stress and temperature conditions significantly affected the fatigue performance under matrix cracking stress.

Summary: SiC/SiC composites are ideal for hot-end components, while mini-composites are commonly used to study ceramic matrix composites. This study investigates the influence of strain rate on the mechanical properties of mini-SiC/SiC composites and establishes a constitutive model based on the Michaelis-Menten and generalized linear models.

Summary: The mechanical properties of pressureless sintered samples of alpha-SiC based composite containing graphene and nano beta-SiC were investigated. The usage of nano beta-SiC and graphene led to the elongation of alpha-SiC grains, resulting in improved mechanical properties. The combination of 5 wt.% nano beta-SiC and 1 wt.% graphene showed the highest density, modulus, and fracture toughness.

Summary: The Water-Cooled Lead-Lithium Breeding Blanket (WCLL BB) is a candidate for the driver blanket of the EU-DEMO reactor, designed with a holistic approach that considers various factors such as neutronics, thermal-hydraulics, thermo-mechanics, and magneto-hydro-dynamics. The layout of WCLL BB is able to meet different requirements, including integration, tritium self-sufficiency, and thermal and mechanical needs. The design choices and characteristics of WCLL BB for EU-DEMO are discussed, along with achievements and remaining issues to be investigated further in the upcoming design phase.

Summary: SiC/SiC composites prepared through precursor infiltration and pyrolysis (PIP) and chemical vapor infiltration (CVI) exhibit different microstructures and mechanical properties. PIP composites showed cracks and amorphous crystal structure, while CVI composites had tightly bonded matrix without cracks and high crystallinity. After heat treatment, PIP composites experienced significant decrease in bending strength and modulus, while CVI composites maintained good mechanical properties.

Summary: This study systematically investigates the effect of fibre length on the mechanical performance of MJF-printed GF/PA12 composites, showing that longer fibres promote fibre alignment but also increase porosity in the composite parts. When GFs with an average length of 226 pm are added, the ultimate tensile strength and tensile modulus of the composites are significantly improved in the powder bed spreading direction.

Summary: The study investigates the microstructural features, mechanical properties, and porosity of laser powder bed fusion (LPBF)-fabricated Al matrix composites reinforced with SiC particles. The results show that the LPBF-deposited composites mainly exhibit laser track segments in macroscale and fine cellular-like dendrite grains and (Al + Si) eutectic phases within the melt pool on a microscale. The study also analyzes the influence of oxidation temperatures on the SiC particle features and the stress and strain distribution in the deposited composites.

Summary: The most significant challenge in developing structural materials for in-vessel components in the DEMO fusion reactor is qualifying the lifetime of materials. This qualification needs to be done theoretically due to the unavailability of actual fusion environment experiments. Uncertainties arise from irradiation data and loading conditions, which can be mitigated using a probabilistic approach. A case study on the Japanese DEMO breeding blanket highlights technical issues and suggests directions for fusion structural materials development.

Summary: This study presents a new method of producing high-quality SiC/SiC ceramic-matrix composites. A SiC slurry with binders was used to impregnate SiC fibers and form green sheets without fibers, which were then sandwiched between two SiC green sheets and warm-pressed. The resulting composites exhibited excellent bending strength and tensile properties due to the controllable sheet thickness and smoother fiber bundles of the sandwich prepreg sheets.
