Manufacturing and Properties of the Fibrous/Aluminum Foil Thermal Insulation Composite

Abstract

Heat energy is essential in the human’s life, and it is an important resource in the economical and social development. In this study, the fire-retardant fibrous materials (FR-FTI) were prepared by the fire-retardant polyester fibers (FRPF) and the low melting point polyester fibers (low-Tm fibers). The linear-density of the FRPF, the layers of the loose nonwoven and the low-Tm fiber content were changed in the preparation of the FR-FTI. The thermal conductivity of the FR-FTI, tensile strength and the LOI was evaluated to study the processing parameters on the properties of the FR-FTI. Besides, the aluminum foils were placed between the loose nonwoven of the FR-FTI to prepare the FR-FTI/A. the thermal conductivity of the FR-FTI was estimated to study the influence of the addition of the aluminum foils on the thermal transfer ability of the composites. The results showed that the effect of the low-Tm fiber content was interacted with the effect of the layer number of the loose nonwoven on the thermal conductivity of the FR-FTI.
