The thermal conductivity and thermal diffusivity of oil-palm-fiber-reinforced untreated (Sample 1) and differently treated composites were measured with the transient plane source technique at room temperature and under normal pressure. All the composites were 40% oil-palm fiber by weight. The fiber
## Abstract The effective thermal conductivity (Ξ»~__e__~) and effective thermal diffusivity (Ο~__e__~) of oilβpalmβfiberβreinforced treated composites were measured simultaneously with the transient plane source technique from 50 to 110Β°C. The fibers of the composites were treated with sodium hydro
