Abstract

New polyurethane composites have been prepared by treatment and functionalized of waste leave sidr powder with polymeric methylene diphenylene diisocyanate (PMDI), and the mixing effect on the properties of this composites was evaluated using different weight percentage of carbon fibers (CFs). Thermal treatment of the prepared natural composites were conducted in different temperatures and the XRD,SEM studies showed the heat treatment at 9000C ,. the flammability test of this composites and hybrid composites ( containing different % of CF ) were analyzed using UL-94V methods, the results showed that these prepared composites were flammability and fire resistance. as well as , the effect of CF on the ablation properties was evaluated using oxygen-acetylene ablation device, and along with the increasing of their the content of CFs, the mass and linear ablation rates both decreases, while the insulations index were increase.
