life cycle.    The main objective of this research was to develop soy-based polyurethane foam reinforced  with multi-walled carbon nanotubes to enhance the compressive and mechanical properties. Soy-  based Soy-based  polyurethane / carbon nanotubes composites with loadings of 0.5 and 1.0 wt\% were synthesized. The effects of kenaf content on the properties of soy-based polyurethane foam composites were investigated.
