Abstract

Based on an overall analysis of load carrying, energy absorption and thermal insulation performances of metallic foam cored sandwich structures, new hybrid sandwich structures were developed in the present study by inserting lightweight, efficient thermal insulating interlayers between the face sheets and the foam core. Optimum selection was made by studying and comparing the thermal insulation performance, load carrying capacity and energy absorption capability of different topological configurations of the sandwich structures. The structural responses of the traditional sandwich panel and the optimized multilayer sandwich panel at different temperatures were also experimentally studied and compared. The thermal conductivity decreased by 58.33 %, and energy absorption improved by 49.02 % at a particular temperature for the sandwich structure of Type 3 compared to traditional panels.

复合夹层结构高温保温与承载性能试验研究

在对金属泡沫芯夹芯结构的承载、吸能和保温性能进行综合分析的基础上，通过在面板与泡沫芯之间插入轻质高效保温夹层，研制了新型复合夹芯结构。通过对不同拓扑构型夹层结构的保温性能、承载能力和吸能能力的研究和比较，进行了优化选择。对传统夹层板和优化后的多层夹层板在不同温度下的结构响应进行了实验研究和比较。在特定温度下，与传统面板相比，3型夹层结构的导热系数降低了58.33%，能量吸收率提高了49.02%。
