“…A review of lattice structures with negative Poisson's ratio is introduced in [109]. Hence, owing to this unique property, the metamaterials structures find their applications in various fields such as stiffness under quasi and impact loading [110], sinusoidal loading [111], impact energy absorption [112], tension-twist coupling effects [113], axisymmetric chiral auxetic structures [114], structure design and mechanical properties [115,116,117], etc.…”

Metamaterials, commonly known as synthetic composites with exotic dynamic characteristics, have recently generated increasing interest. A short description of composite metamaterial and their types, applications, and manufacturing techniques was reported. Contrary to all previous research, this investigation focuses on the recent studies of static and dynamic analysis of composite metamaterial structure and mechanical performance using experimental and finite element method analyses. Furthermore, the literature has described several methods for constructing composite sandwiches, properties, and advantages over conventional materials. Due to the wide variety of materials and configurations used in the final product, there is a corresponding diversity in manufacturing techniques. Therefore, the current research has mainly concentrated on a wealth of information that should be important to all researchers interested in keeping up with the most recent developments in composite metamaterial sandwich structures. Consequently, this study can be considered a guideline for researchers who intend further research on the mechanical behavior analysis and technology of designed composite metamaterial structures.

“…HACPs can dissipate and mitigate the imparted energy more efciently than conventional honeycomb panels. Song et al [28] designed a new threedimensional double-arrow negative Poisson's ratio structure for an automobile crash box, which achieved better energy absorption than a traditional crash box. Liu et al [29] studied the energy-absorbing performance of re-entrant honeycomb and positive hexagonal honeycomb structures under in-plane impact loading.…”

A ship equipment pedestal is a structure that connects power equipment to a hull. It must have a high load-bearing capacity and the ability to withstand large impact loads. In this paper, a novel structure with a positive-negative Poisson’s ratio is proposed. The deformation mechanism and mode of this structure under quasistatic compression loading are analysed via numerical simulation. Based on this new structure, a multicellular pedestal is designed, and its bearing capacity and impact resistance are analysed. The structural parameters of the pedestal are optimized. An experiment is conducted to evaluate the impact resistance of the pedestal model, which confirms that the proposed multicellular pedestal exhibits excellent impact resistance.

“…Negative Poisson's ratio structures (NPRSs), owning their unusual characteristic of getting fat when stretched and thin when compressed, [1][2][3] have been popular in the fields of medical, protective devices, and smart sensor. [4][5][6][7] The realization of the negative Poisson's ratio effect requires the correct combination of geometry and deformation mechanism, and does not depend on the scale. 8 According to the deformation mechanism, the NPRSs can be classified into rotating units type, 9,10 chiral type, 11,12 re-entrant type, [13][14][15] and other types.…”

In this work, continuous fiber reinforced thermoplastic negative Poisson's ratio structures (CFNPRSs) with rotating squares are fabricated by 3D printing based on a symmetrical orthogonal and one‐stoke path planning method. The influences of the printing path on the Poisson's ratio, elastic modulus and energy absorption of the structures under compression are systematically researched. The distribution of continuous fiber at the hinge has a great influence on the compression behavior of the structures. As the number of cross laps of continuous fibers at the hinge increases, the negative Poisson's ratio effect decreases while the elastic modulus and energy absorption increase. The printed CFNPRSs with no cross lap have the most obvious negative Poisson's ratio effect, with an average Poisson's ratio of −0.61. A comparative study on Poisson's ratio of the 3D printed polylactic acid negative Poisson's ratio structures (PANPRSs) is carried out, and the results show that the PANPRSs cannot achieve the negative Poisson's ratio effect because the insufficient stiffness of the printed rotation units violates the rigid assumption in theoretical model. Furthermore, the printed CFNPRSs with a lower relative density of 0.18 has an even better negative Poisson's ratio effect than the existing fiber‐reinforced auxetic structures fabricated by 3D printing. This work can provide a significant reference for the preparation of lightweight functional structures using 3D printing.Highlights The CFNPRSs with rotating squares are prepared by 3D printing technique. The path planning of the fiber at the hinge affects the properties of CFNPRSs. The negative Poisson's ratio of CFNPRSs is more obvious than that of PANPRSs. The relative density and Poisson's ratio of CFNPRSs have obvious advantages.
