N2 - Natural fibers made into cellulose have attracted interest in the research and development of composite materials in recent years. One of them is Kenaf fiber from Sumberejo, East Java. The Kenaf fiber nanocellulose reinforced polyurethane (NC-PU) composites were prepared via in-situ polymerization. The purpose of this research is to analyze the thermal properties and morphology of PU and NC-PU composites. Then, TGA (thermogravimetric analysis), DTG (differential thermogravimetric analysis), DSC (differential scanning analysis) and SEM (scanning electron microscope) are applied to characterize PU and NC-PU composites. The addition of nanocellulose up to 7 wt.% in polyurethane was found to decrease the melting temperature of NC-PU composites and decrease the rate of decomposition. The lowest decomposition rate is attributed to the composite material of 10 wt.% NC-PU, which has a decomposition rate of 1.7 %/min, and the highest residual decomposition rate of 67 %. The addition of nanocellulose to PU also decreases the average pore size of NC-PU composites
