“…In the design of wind turbine systems, the selection of materials is a critical factor. The properties of materials used in constructing wind turbines significantly influence their efficiency, durability, and overall performance [191]. These materials must withstand diverse environmental conditions, manage mechanical stresses, and contribute to the aerodynamic efficiency of the turbines.…”

The field of wind energy stands at the forefront of sustainable and renewable energy solutions, playing a pivotal role in mitigating environmental concerns and addressing global energy demands. For many years, the convergence of nature-inspired solutions and wind energy has emerged as a promising avenue for advancing the efficiency and sustainability of wind energy systems. While several research endeavors have explored biomimetic principles in the context of wind turbine design and optimization, a comprehensive review encompassing this interdisciplinary field is notably absent. This review paper seeks to rectify this gap by cataloging and analyzing the multifaceted body of research that has harnessed biomimetic approaches within the realm of wind energy technology. By conducting an extensive survey of the existing literature, we consolidate and scrutinize the insights garnered from diverse biomimetic strategies into design and optimization in the wind energy domain.

The woven lattice sandwich composites (WLSCs) are susceptible to damage during service, which leads to a decline in their mechanical properties. Therefore, it is crucial to develop repair methods that specifically target the mechanical properties of WLSCs. In this study, repair techniques for the common types of skin and core damage in WLSCs were propose. The repair process begins with identifying the type of structural damage and removing the damaged section. Subsequently, the skin and core layers are repaired accordingly. The mechanical properties before and after repair are then compared through experimental evaluations. The results demonstrate that the carrying capacity of the repaired WLSCs is 85% higher than that of the original, unrepaired structure using the selected repair method.Highlights Typical damage modes of woven lattice sandwich composites were classified. Repairing methods are proposed for woven lattice panels based on damage modes. Core‐foaming and skin patch adhering perfectly rehabilitate the damaged sandwich. Bearing capacity of the repaired sandwich slightly surpasses its original structure.
