Summary: In this study, a general potential energy for multiphase coupled multiferroics is defined, and the coupled governing equations are derived using the minimum energy principle. The equations are then discretized into a three-dimensional finite element model using the COMSOL software. After validation, the model is applied to analyze and design the common sandwich structure of multiferroics composites. The effects of boundary conditions, material grading, nonlinearity, and polarization orientation on the composites are analyzed under typical static loading, providing valuable insights for designing high-performance multiphase composites.

Summary: This study utilized polarized Raman spectroscopy to assess the strain in aligned multi-walled carbon nanotube/epoxy composites, aiming to clarify the effective elastic modulus of the carbon nanotubes. The Raman shift rate of the G' band of the carbon nanotubes was found to be 18.84 cm(-1)/% corresponding to the tensile strain of the composite specimen. Through Mori-Tanaka theory and consideration of the three-dimensional orientation distribution of the carbon nanotubes, the effective elastic modulus of the carbon nanotubes was estimated to be 400 GPa. The results demonstrated the utility of Raman spectroscopy in experimentally evaluating the effective elastic modulus of multi-walled carbon nanotubes in composites.

Summary: This paper developed a parametric model for fine weave pierced carbon/carbon composites and studied the mechanical properties of composites with different yarn contents. The results showed that increasing the amount of Z-directional yarns significantly improved the modulus and compressive strength of the composites, while the X/Y-directional performance slightly decreased. The accuracy of the model prediction using Hashin failure criterion was better than that of the Hoffmann criterion. The composite failure mainly occurred in the compressive failure regions of the yarns or fibers.

Summary: Determining failure strains is crucial for the design of composite structures. Tensile tests were conducted to evaluate the ultimate strains of a composite with various fiber orientations. The obtained ultimate tensile strengths exhibited low or moderate dispersion, with the average values providing a good estimation of failure stress. However, failure strains showed high dispersion for almost all orientations, indicating the need to use the minimum value as the failure strain threshold. Additionally, the shear behavior of the material was assessed.

Summary: MXene and BP sensors embedded in composite overwrap have similar sensitivity, but BP sensor is more sensitive to the initiation and propagation of microcrack in COPV. MXene sensor is more sensitive to plastic deformation or compressive residual strains at the interface between the aluminum liner and composite overwrap. BP sensors are effective for real-time damage condition monitoring of composite, while MXene sensors are more suitable for performance and structural health condition monitoring of aluminum liner.
