Thermal Insulation Properties of Biodegradable, Cellulosic-Based Nonwoven Composites for Automotive ApplicationSouthern Regional Research Center USDA, New Orleans, LA, USAyachmene{at}srrc.ars.usda.gov
Southern Regional Research Center USDA, New Orleans, LA, USA Moldable, cellulosic-based nonwoven composites with excellent thermal insulation properties were fabricated from kenaf, jute, flax, and waste cotton using recycled polyester and substandard polypropylene. The composites of these fibers have excellent shape stability and high tensile and flexural properties coupled with economic and environmental benefits. Four different designs incorporating different cellulosic fibers, manufacturing techniques and various ratios of vegetablesynthetic fibers were manufactured on laboratory-scale equipment. A Steady-State Heat Flow meter was used for measurement of thermal conductivity and thermal transmittance of samples of composites. The data show that thermal insulation properties of the cellulosic-based nonwoven composites vary significantly, depending on the type of the cellulosic fibers, the ratio of cellulosic fibers to synthetic fibers, and the resulting density of the composite.
