Summary: This study investigates the use of Ti3C2Tx MXene nanosheets deposited via electrophoretic deposition (EPD) to enhance the interfacial properties of high modulus carbon fiber (HMCF) composites. The EPD process allows for control over the deposition density and content of Ti3C2Tx MXene nanosheets on the HMCF surface. The results show that the introduction of Ti3C2Tx MXene nanosheets improves the surface morphology and energy of the HMCF, leading to significant increases in interfacial shear strength and interlaminar shear strength of the composites.

Summary: Polyacrylonitrile (PAN) nanofiber-sheathed Basalt fibers (BFs) were prepared using the electrospinning method and further used to synthesize novel BFs-reinforced epoxy composites with enhanced interfacial properties, showing a 31.33% increase in interfacial shear strength (IFSS). The improvement mainly comes from the formation of a gradient interfacial layer, enabling uniform stress transfer and promoting interfacial adhesion between BFs and the epoxy matrix. This method is suitable for cost-efficient, continuous large-scale production.

Summary: A modified constitutive model based on the hyperbolic sine Arrhenius equation was proposed in this study to analyze the deformation mechanism of Ti-6Al-4V alloy during superplastic forming. The relationship between constitutive model parameters and forming mechanism was established, providing a new angle in rheological behavior research and constitutive model analysis. The findings indicated that the modified constitutive model had a good ability to describe the flow behavior of Ti-6Al-4V in superplastic forming, and a deformation map of titanium material was obtained based on the parameters.

Summary: This paper presents an inverse computation method for measuring the anisotropic plasticity properties of materials using indentation. The method treats material plastic parameters as stochastic variables with statistical distributions, and establishes a Bayesian inference model based on imprint snapshots of anisotropic materials in spherical indentation. Proper orthogonal decomposition is used to correlate material parameters with indentation imprint snapshots in a dimension-reduced sub-space, and weighting is applied to balance errors from imprint snapshots.

Summary: Grain size plays a crucial role in the quality of diffusion bonds in superplastic forming and diffusion bonding. Fine-grained materials with many grain boundaries act as short-circuit paths for diffusion, facilitating bonding, and also have faster grain-boundary migration compared to coarse-grained materials. Fractographic studies show that coarse-grained specimens exhibit larger dimples and heterogeneous deformation during tension compared to fine-grained materials.

Summary: This study investigates the influence of relative position and dimensional parameters of pin and impactor on foam core sandwich structure under low-velocity impact using experimental and computational approaches. It was found that the enhancement impact was substantial when the position parameters were below one and negligible when above three. The deformation and damage patterns of the pins transitioned from crushing to bending and micro-buckling with increasing position parameters. In addition, the position parameters had higher significance on maximum contact force, damage resistance, and perforation threshold energy, while the dimensional parameters had higher significance on dent depth.
