Meta-materials of Re-entrant Negative Poisson's Ratio Structures Made from Fiber-Reinforced Plastics: A Short Review

Negative Poisson's ratio (NPR) structure is a common mechanical meta-material that has great potential in impact protection engineering due to its special indentation resistance. There are many studies on the NPR structures, but there are still few reports on the NPR structures with the parent materials of fiber-reinforced plastics (FRPs). As a type of advanced functional composites, the FRPs have higher specific modulus and specific energy absorption, and have become the most popular lightweight materials. In this review, the characteristics of NPR structures and FRPs were first analyzed and then the existing structure shapes, material types, manufacturing processes and mechanical behaviors were reported and discussed. Finally, the future direction of the mechanical meta-materials with the NPR structure was explored based on the current engineering requirements and preparation technologies. This review is expected to attract more scholars to pay more attention to the NPR structures fabricated by the FRPs.
