Design and Performance Evaluation of Flame Retardant and Thermally Insulated Material-Integrated Multi-Functional Thermoplastic Corrugated Sandwich Panels

Abstract

Multifunctional composite panels for flame retardant and thermal insulation have not yet been studied. In the current study, we prepared sandwich sheets by using continuous glass fiber flame retardant polypropylene prepreg tape and compared the thermal insulation properties of different fillings. Corrugated sandwich panels, featuring a corrugated space filled with different materials, were prepared and their thermal and mechanical properties are tested and verified. Determining the two structural parameters that have the greatest influence on the heat transfer performance of corrugated sandwich panels has important guiding significance for the structural design of corrugated panels.
