Thermal Diffusivity of Polyurethane Composites Filled with Industrial Waste Fabrics

抄録

The polyurethane composites filled with waste fabrics obtained from apparel industries were prepared. Sodium lignosulfonate (LS) was dissolved in polyethylene glycol (PEG) and the above polyol system was mixed with industrial waste fabrics. Filler content was varied from 60 to 80 % to total mass. Fracture surface of composites was observed by scanning electron microscopy. Thermal diffusitivity was calculated assuming diffusion occurs one dimensionally. Calculated values were filler 80%; 2.8x10^-8 m²/s, 70%;4.8x10^-8 m²/s, and 60% ; 6.5x10^-8 m²/s, respectively. It is concluded that waste fabric has a potential to utilize as a filler of composites designed for insulators.
