A new cultivar of Carex plant named ‘Lunar Falls’ that is characterized by its variegated foliage with wide white margins, its fast growing plant habit with a one-gallon plant produced in one season, its ease of propagation by division, and its very stable variegation with no solid white or green shoots observed.

The application discloses a kind of imitated carex buffer energy-absorbing thin-walled composite structures, including by a plurality of imitated carex crescent structure symmetrical combination and form bionic structure, imitated carex crescent structure includes outer arc plate, inner arc plate, the connecting flat plate for connecting the side of outer arc plate and inner arc plate and the several rib plates that are evenly distributed between outer arc plate and inner arc plate.The bionic structure of the application is combined by imitated carex crescent structure, is derived from the design of the internal characteristics of carex, and the whole bionic structure contains multiple levels of morphology and can effectively promote the bionic structure to disperse the impact energy to different structural levels when being subjected to axial impact, thereby buffering the impact force acting on the structure surface.The stress on the outside of the crescent is greater than the stress on the inside during the impact process, resulting in uneven stress on the crescent structure, effectively preventing structural instability and enhancing the impact resistance of the structure.Therefore, the whole bionic structure can effectively improve the carrying capacity and buffer energy-absorbing characteristics, ensuring a certain initial peak force and total energy absorption.
