Summary: In this study, three-dimensional woven spacer glass fiber/epoxy composites and epoxy foam-filled three-dimensional woven spacer composites were prepared and their behavior under bending load was investigated experimentally and numerically. It was found that the foam-filled composites exhibited higher bending strength and stiffness compared to the non-foam-filled composites, and also showed less damage under bending load. The finite element analysis results were in good agreement with the experimental results, indicating the potential of using numerical simulation to study the bending properties of these 3D composites.

Summary: In this study, integrated 3D woven spacer composites (3DWSC) with double-layer cores assembled at different height combinations were designed and prepared to improve their anti-impact property. The results showed that the 3DWSC-4+8 combination had the highest contact force value and residual compressive strength after impact compared to single-layer 3DWSC. Moreover, SEM images revealed exceptional mechanical stability of the as-prepared double-layer 3DWSC with no fiber breakage and delamination. This work provides a reference for the design and fabrication of multi-layer 3DWSC, a promising material in high-performance composites.

Summary: Gradient three-dimensional (3D) orthogonal preforms were manufactured through the flexible oriented 3D woven process (FO3DWP) with varied fiber volume fractions and z-yarn contents. Micro-computed tomography (micro-CT) technology was used to measure and regulate the layer porosity distribution of the preforms. The gradient design improved the out-of-plane compression strength of the 3D woven composites, with the highest strength observed in a composite with a fiber volume fraction of 0.46 and z-yarn volume fraction of 0.05.

Summary: This paper investigates the mechanical behavior and failure mechanism of a novel Al matrix composite reinforced with 3D orthogonal woven carbon fibers. Through numerical and experimental approaches, the quasi-static tensile behavior, local stress response, and progressive failure process are studied. The results show that the calculated stress-strain curve agrees well with the experimental curve, and the composites exhibit apparent periodic and heterogeneous stress distribution. Interface debonding and transverse cracking contribute to the nonlinear response and catastrophic rupture of the composites. Based on the validated model, the influence of fabric structure parameters on the macroscopic properties is further evaluated.

Summary: In this paper, a new form-finding method based on spatial elastica model (FMSE) is proposed for elastic gridshells. The method integrates the deformations of elastic rods into the overall deformation of the gridshell, and solves a set of transcendental equations using the quasi-Newton method to ensure the deformation satisfies the given boundary conditions. The method is validated through experiments and expected to have potential applications in the investigations of elastic gridshells.

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: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).

Summary: This paper presents a study on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. The specimens were tested under compression loading conditions to investigate post-buckling and failure in aerospace structures. Experimental results and numerical simulations were compared to analyze the behavior and failure modes of the specimens. The study found promising evidence of a viable solution to optimize aeronautical structures and enhance resistance to skin-stringer separation, particularly with the use of tapered flanges.
