Sandwich structures are a class of multifunctional high-performance structural composites that have the advantages of being lightweight, of a high strength-to-weight ratio, and of high specific energy absorption capabilities. The creative design of the core along with the apposite material selection for the fabrication of the face sheet and core are the two prerequisites with encouraging areas for further expedition towards the fabrication of advanced composite sandwich structures. The current review work focused on different types of core designs, such as truss, foam, corrugated, honeycomb, derivative, hybrid, hollow, hierarchical, gradient, folded, and smart core along with different composite materials accessible for face sheet fabrication, including fiber-reinforced composite, metal matrix composite, and polymer matrix composite are considered. The joining method plays a major role for the performance evolution of sandwich structures, which were also investigated. Further discussions are aligned to address major challenges in the fabrication of sandwich structures and further enlighten the future direction of the advanced composite sandwich structure. Finally, the work is summarized with a brief conclusion. This review article provides wider guidelines for researchers in designing and manufacturing next-generation lightweight multilayer core sandwich structures.

“…Feih et al [ 15 ] conducted a tensile test on carbon fibers and CFRP laminate under a high temperature of 250–700 °C, and the results indicated that the tensile strength and modulus of carbon fiber were reduced by nearly 50% following exposure to temperatures over the range of 400–700 °C due to the oxidation of the higher stiffness layer in the near-surface fiber region. Based on the high-temperature mechanical properties of laminates and their components, researchers conducted comprehensive studies on the composite sandwich plate exposure to a high-temperature environment [ 16 , 17 , 18 , 19 ]. These experimental tests were conducted on a universal test machine, and the data were recorded by the displacement transducer on the machines.…”

Carbon fiber-reinforced polymer (CFRP) has the advantages of a high strength-weight ratio and excellent fatigue resistance and has been widely used in aerospace, automotive, civil infrastructure, and other fields. The properties of CFRP materials under high temperatures are a key design issue. This paper presents the quasi-static tensile mechanical properties of unidirectional CFRP plates at temperatures ranging from 20 to 600 °C experimentally. The laser displacement transducer was adopted to capture the in situ displacement of the tested specimen. The results showed that the tensile strength of the CFRP specimen was affected by the high-temperature effect significantly, which dropped 68% and 16% for the 200 and 600 °C, respectively, compared with that of the room temperature. The degradation measured by the laser transducer system was more intensive compared with previous studies. The elastic modulus decreased to about 29% of the room temperature value at 200 °C. With the evaporation of the resin, the failure modes of the CFRP experienced brittle fracture to pullout of the fiber tow. The study provides accurate tensile performance of the CFRP plate under high-temperature exposure, which is helpful for the engineering application.

In this paper, a new manufacturing method of pyramidal lattice cells has been suggested to produce lattice composite cylinders. Moreover, the effect of fiber volume fraction, vacuum molding, and fiber pre-tension has been investigated on the load-carrying capacity of the cylindrical pyramidal lattice structure of a carbon fiber composite. The carbon fiber composite cylindrical pyramidal lattice structure has been manufactured with laying fibers along the grooves of a silicone mold. Then, it has been subjected to the axial compressive test. Furthermore, to make pre-tension in fibers, a metal mold has been designed. Fiber pre-tension ensures the alignment of the fibers is straight between two nodal points. Additionally, the structure has been analyzed by the finite element buckling procedure. Experimental tests on the structures show that using a metal mold compare to the silicone molding method increases load-carrying capacity up to 48% without significantly varying the weight. Therefore, this method can be used for manufacturing pyramidal lattice structures in the hand layup process.
