Summary: Three microstructural models were constructed based on 3D7d braided preforms and their relationships with braiding angles, fiber volume fractions, and yarn filling factor were investigated. The results showed that the longitudinal modulus and tensile strength decreased with increasing braiding angles, while the transverse modulus and strength were opposite. Furthermore, higher fiber volume fractions improved the performance of the composites.

Summary: The conventional evaluation of 3D braided composites' mechanical properties through numerical and experimental methodologies hinders material application due to the expenses, time constraints, and laborious efforts involved. This study establishes a multi-scale finite element model and a surrogate model for predicting the elastic properties of 3D4D rotary braided composites with voids. By optimizing a neural network model, the results are validated and provide valuable insights into the microstructure and properties of these composites.

Summary: The viscoelastic behavior of 3D braided composites with pore defects was investigated using multiscale modeling, focusing on the yarns. The results show that pore defects can significantly reduce the transverse viscoelastic behavior of the composites, while having smaller effects on longitudinal long-term properties. The study also highlights the sensitivity of longitudinal properties to braiding angles compared to the transverse direction.

Summary: The compression properties of unidirectional braided composites were studied, and it was found that a slight variation in braid angle had a significant effect on the compression modulus. Unidirectional over-braided multilayer composites had higher compression modulus and strength compared to two-dimensional over-braided multilayer composites, but lower structural stability.

Summary: A coupled micro-meso-scale modeling strategy is proposed to investigate the damage mechanism of 2D SiC/SiC ceramic matrix composites. The effective properties of the SiC/SiC yarn are computed using the micro-scale RVE model, and the Tsai-Wu and Mohr's failure criteria are used at meso-scale to describe different failure modes. The proposed multi-scale modeling strategy is validated by experimental results from uniaxial tension tests, and further investigation is done on the damage behavior of 2D SiC/SiC composites under in-plane shear loading.

The optimized response surface was achieved at eight cycles, an output level of 42, and a gain of 32 dB, providing operational stability, high accuracy, and reliability for the nonlinear ultrasonic detection system.

Summary: This study investigates the mechanical behavior of plain woven Carbon Fiber-Reinforced Polymer (CFRP) composites under Three-Point Bending (TPB) using experimental and numerical approaches. Multiscale models are developed to characterize the TPB strength and damages, and the effective properties of carbon-fiber yarn and CFRP composites are determined. An Equivalent Cross-Ply Laminate (ECPL) cell is proposed to simplify the woven architecture, and a local homogenization approach is applied to compute the effective properties of the subcell. The TPB experiments validate the multiscale models, which reveal that delamination, matrix cracking, and delamination are the significant damage modes during the TPB process.

Summary: For a long time, the arrangement of leaves on a plant stem, known as phyllotaxis, has been observed as an interesting morphological property. The phyllotactic spirals, determined by the Fibonacci sequence or the golden ratio, have now expanded beyond plants and are found in architectural and structural design. In this study, we developed a design approach for curvilinear stiffening ribs based on the Fibonacci spiral pattern. We analyzed the mechanical advantages of this pattern in stiffening structures and explored its applications in various designs, including planar and curved surfaces.

Summary: A novel hybrid metamaterial is developed by filling a hyperbolic chiral lattice with polyurethane (PU) foam. The foam is able to soften the body-centered cubic (BCC) lattice and stiffen the hyperbolic one, as shown by monotonic compressive tests. The foam hybridization also helps to prevent property degradation of the hyperbolic lattice under cyclic compression.
