Exploration of Jute-HCP Composites Material for Building Environments

ABSTRACT

Jute and hollow conjugated polyester fiber (HCP)-reinforced nonwoven composites were designed by Box and Behnken model approach. Its thermal properties such as thermal conductivity, thermal resistance, thermal transmittance, and thermal diffusivity were evaluated. From the test results of response surface method (RSM), the weight of composite material maintained as 3280 g/m² with the proportion of jute/HCP fiber in the ratio of 50/50%, 60/40%, and 70/30% played a significant role in insulation and mechanical properties. Various needling density maintained on the composite material such as 300, 150, and 75 punches/cm² contributes to the role of significant impacts on the research process. The optimum of 150 needling density with the proportion of 50/50 Jute and HCP fiber was selected to produce four kinds of composite structures. Its thermal, sound, electrical insulation values and limiting oxygen values were analyzed and suggested for building environments.

摘要

黄麻和中空结合聚酯纤维（HCP）增强无纺布复合材料采用Box和Behnken模型方法设计. 评价了其热导率、热阻、热透射性和热扩散率等热特性. 从响应表面法（RSM）图的测试结果来看，复合材料的重量保持在3280克/平方米，黄麻/HCP纤维的比例为50/50、60/40和70/30%，对绝缘和机械性能有显著作用. 在复合材料上保持的各种需要密度，如300、150和75冲孔/cm2，有助于对研究过程产生重要影响. 选取了150个配比密度的最佳，比例为50/50黄麻和HCP纤维，可产生四种复合结构. 对建筑环境的热、声、电绝缘值和限制氧值进行了分析和建议.
