QUASI-STATIC AND DYNAMIC COMPRESSION TESTS AND ENERGY ABSORPTION PROPERTIES OF CORRUGATED COMPOSITES

摘要

Based on the Quasi-static and dynamic compression tests of the four types of corrugatedrncomposite materials of different structure, this paper expresses the cushioning and energyrnabsorption efficiency of these materials with the maximum deformation energy of materials perrnunit volume and unit mass. The maximum deformation energy of corrugated composite materialsrnin the dynamic compression test is far greater than that in the static compression test. The foldedrncorrugated composite materials have the highest compression resistances and absorb the greatestrndeformation energy in the static compression. 0/90/0 cross overlapping corrugated compositernmaterials and 0/0/0 parallel overlapping corrugated composite materials have similar cushioningrnproperties, low compression resistances, but good rebound elasticity. Therncorrugated/honeycomb/corrugated structure greatly enhances the thickness of compositernmaterials with little materials, and it has an improved cushioning and energy absorptionrnefficiency compared with the simple corrugated overlapping structure.
