Coreless filament winding is a manufacturing process used for fiber-reinforced composites, resulting in high-performance lightweight lattice structures. Load transmission elements, which are assembled from commercially available standardized parts, often restrict the component design. A novel adaptive winding pin was developed, which is made by additive manufacturing and can therefore be adjusted to specific load conditions resulting from its position within the component. This allows to decouple the fiber arrangement from the winding pin orientation, which allows a fully volumetric framework design of components. A predictive model for the pin capacity was derived and experimentality validated. The hooking conditions, pin capacity, and occupancy were considered in the creation of a digital design tool.

“…[8–13] presented continuous models for buckling and structural analyses of composite structures and dealt with optimization via the continuous model. The mechanical characteristics of honeycomb sandwich structures were investigated based on simplified theories and models and the finite element method [14–17]. Hassan [18] dealt with a simplified methodology for the analysis of sandwich structures based on the homogenization method and presented the equivalent stiffness of sandwich structures with complex hexagonal cores using numerical/experimental methods.…”

This article presents a theoretical formulation presented for conducting a buckling analysis of the composite sandwich plate with multiple holes via the homogenization method. The validity of the theoretical formulation was verified by comparing the results of the finite element analysis and experimental analysis. Finally, the theoretical formulation was used to optimize a composite sandwich plate with multiple holes for the design of an aircraft structure to minimize the mass. The optimization result allows a database to be obtained on the buckling characteristics of composite sandwich structures with multiple holes for applying aerospace applications. We then concluded that the theoretical formulation is well-suited to buckling analysis of a composite sandwich structure with multiple holes for aerospace applications due to their relative simplicity and computational efficiency.

“…[1][2][3] Particularly, carbon fiber (CF) composites are favored by researchers because of their mechanical properties of high specific strength and high specific modulus. [4][5][6] Conventional CF reinforced epoxy (CF/Epoxy) laminates often have the following problems in practical applications: high cost, low elongation at break, poor fracture toughness, and difficulty in connecting with other components. [7] Hybrid laminates have received increasing attention from researchers due to their excellent comprehensive performance.…”

Carbon fiber (CF) hybrid laminates with excellent mechanical properties have attracted great attention. Herein, CF reinforced epoxy/polycarbonate (CF/Epoxy/ PC) hybrid laminates are fabricated via laser surface processing and hot-pressing technique. Several mechanical tests, including uniaxial tensile, flexural, and impact, are conducted to assess the effect of stacking sequence on the prepared hybrid laminates. In addition, failure behaviors and morphologies are observed to analyze the interaction mechanism between the two laminates. Experimental results indicate that the tensile properties of hybrid laminates conform to the rules of mixture. The best flexural properties and impact peak force are found in Epoxy-PC hybrid laminates. However, due to the transfer phenomenon of flexural point during the impact process, PC-Epoxy hybrid laminates possess the best impact energy absorption. Furthermore, the introduction of CF/PC laminates greatly mitigates the out-of-plane fracture process of CF/Epoxy laminates during a flexural test. However, its in-of-plane fracture area has a further increase during the impact process, which illustrates the synergetic enhancement ability of hybrid laminates.
