Summary: A significant improvement in mechanical performance was achieved in ZrB2-based ultra-high temperature ceramic matrix composites (UHTCMCs) through the introduction of rare earth oxides, resulting in the formation of ternary boro-carbides of general formula REB2C2. This study investigated the potential routes for synthesizing YB2C2 phases at UHTC sintering temperatures by using different boron sources, and analyzed their microstructure using SEM, XRD, and TEM. The findings showed that the mixture with B4C exhibited the highest selectivity for the formation of YB2C2, and a long carbon fibre reinforced YB2C2 ceramic composite with a flexural strength of 380 MPa was successfully fabricated. The chemical stability of these materials in air was also assessed.

Summary: This study investigates the interlaminar properties of a C/SiC composite produced by Liquid Silicon Infiltration through experiments and numerical analysis. Experimental methods are introduced to obtain pre-cracks with sharp tips at precise locations, and specimens with different thicknesses are used to study the effects of bending stress states in the delamination process. Numerical techniques are utilized to identify the properties of tri-linear Cohesive Zone Models for simulating delamination, without additional assumptions or testing. The study also considers fiber bridging effects and evaluates process zone lengths using different experimental, analytical, and numerical methods. Overall, the study provides qualitative insights into the delamination process of cost-affordable long fiber reinforced C/SiC laminates, and proposes an experimental and numerical protocol that takes into account the scattering of material properties.

Summary: The impact of residual thermal stresses (RTS) on the reusability of CMCs with high-temperature capabilities and ablation resistance was studied. The RTS of ZrB2-SiC ceramic reinforced with carbon fibers was found to depend on fiber anisotropy and fiber coating. Microstructural analysis revealed the presence of residual porosity, cracks, porosity within fiber bundles, volumetric content of the fibers, and degree of dispersion. The level of RTS was determined by comparing stiffness-displacement curves and cyclic dilatometric curves, and its correlation with thermomechanical behavior was evaluated through flexural tests.

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.

Summary: This study systematically investigates the irradiation responses of binary W alloys, focusing on the binding energy of an alloying element with a W self-interstitial atom (W-SIA). Plates of W, W-0.3 at.% Cr, W-5 at.% Re, W-2.5 at.% Mo, and W-5 at.% Ta alloys were irradiated, and the formation of vacancy-type defects, the precipitation of alloying elements, and the changes in hardness were studied. It was found that the addition of Cr and Re effectively suppresses the formation of vacancy-type defects, while Ta and Mo have no significant suppression effect. Irradiation hardening was observed in all materials, but its degree was smaller in the W-5 at.% Re alloy.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
