Influence of nano metals oxide treatment on medium density fiberboard properties made of sunflower straw fibers

In this study the effects of aluminum dioxide (Al2O3) and copper oxide (CuO) metallic nanoparticles, on the physical and mechanical properties of medium density fiberboard (density of 0.7 g/cm3) made with mixture of industrial wooden fibers and sunflower plant stalk fibers were studied. Two levels o...
