瓦楞复合材料静态压缩吸能性能研究

Static Compression and Energy Absorption Properties of Corrugated Composites

基于4种不同结构瓦楞复合材料的静态压缩试验,用单位体积单位质量材料的最大变形能来表征其缓冲吸能效率,比较了4种材料的吸能性能。折叠型瓦楞复合材料的承载性能最高,其静态压缩吸收的最大变形能也较大;0/90/0交叉叠置瓦楞复合材料和0/0/0平行叠置瓦楞复合材料的缓冲性能非常相似,其承载能力不高,但回弹性较好;瓦楞/蜂窝/瓦楞以很少的材料大大提高了复合材料的厚度,且其缓冲吸能效率比单纯的瓦楞叠置有所提高。该研究成果为缓冲用瓦楞复合材料的选用提供了数据支持。

Based on the static compression tests of the four types of corrugated composite materials of different structure, the cushioning and energy absorption efficiency of these materials was expressed with the maximum deformation energy of materials per unit volume and unit mass. The results showed that the folded corrugated composite materials have the highest compression resistances and absorb the greatest deformation energy in the static compression. 0/90/0 cross overlapping and 0/0/0 parallel overlapping corrugated composite materials have similar cushioning properties, which have low compression resistances, but good rebound elasticity. The corrugated/honeycomb/corrugated structure greatly enhances the thickness of composite materials with little materials, and it has an improved cushioning and energy absorption efficiency compared with the simple corrugated overlapping structure. This research afforded useful and basic data for selection of corrugated composites.
