A Double Arrow Type Negative Poisson's Ratio Structure
A negative Poisson's ratio and structure technology, which is applied to the structure field of spatial lattice structure, can solve the complex manufacturing method of double-arrow type negative Poisson's ratio structure, poor compression resistance and impact resistance, and limited use and experimentation. Research and other issues to achieve the effect of design flexibility and operability, strong compressive and impact resistance, and convenient assembly and connection
