Abstract
Based on the concept of periodic structural unit, combined with interlocking technology, a novel X-lattice interlocked sandwich structure (XISS) was proposed in this paper for achieving electromagnetic (EM) wave regulation, heat dissipation and load bearing. Spoof surface plasmon polaritons (SSPPs) structures realized by gradient copper wire arrays were integrated with glass fiber reinforced plastic (GFRP) diaphragm walls, and then interlocked into GFRP X-lattices to form the XISS. EM simulated and experimental results demonstrated that the SSPPs structures could effectively improve the transmission performance, and the average transmissivity was increased by 22 % at frequency range from 6.93 GHz to 13.95 GHz. Moreover, heat transfer simulated results revealed that the X-lattices effectively induced vortex formation, leading to a higher convective heat transfer efficiency and improving the overall Nusselt number by 204.24 % compared to traditional rectangular honeycombs under the same Reynolds number. Besides the advantages above, the good compressive performance of the XISS exhibited the great potential of structural–functional integration designs, offering the broad prospects in practical engineering application.
期刊介绍:
The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials.
The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
