Basalt hybrid woven textile materials for advanced thermal applications

Abstract

The thermal properties of hybrid basalt-polypropylene (B/PP), basalt-polyester (B/PET) and basalt-jute (B/J) as well as non-hybrid structures have been studied. The fabric structures have been developed as plain weave (PW) for B/PP, B/PET & B/J; matt weave (MW) for B/PP, B/PET & B/ J; and 1/3 twill weave (TW) for basalt-PP, basalt-PET, and basalt–Jute along with the non-hybrid fabrics. The thermal properties of the fabrics, such as thermal conductivity and thermal resistance are studied along with the physiological behavior. Thermal properties are measured by Alambeta and TCi. Correlation between theoretical and experimental measurement of thermal conductivity are also studied. Air permeability is tested by air permeability tester. Based on the results, the influence of fabric structure on specific thermal insulation parameters are analyzed. The findings show that there is a significant impact on thermal properties of basalt hybrid woven structures by geometrical parameters of weave. Structure and fibre type have strong influence on thermal properties. Twill weave structures show higher air permeability and thermal resistance in all combinations.
