he importance of the application of composites in high-tech industries especially in aerospace and automobile industries
have been improved nowadays due to their good properties such as high strength with respect to weight. Among different
types of composites, wooden composites have a special importance in various industries due to their energy absorption as
lightweight structures with modified ballistic capabilities. In this paper, the effects of alumina (Al

) nanoparticles on the
mechanical properties of medium density fiberboards (MDF) have been reported. The thickness of boards and the percentage
amount of Nano-alumina were considered as variables. In this research, the combination of forest and garden fibers, due to
their excellent abrasion resistance, as well as their affordability and suitable price were used as a composite field, with Nano-

powder (APS: 20nm) as a hardening phase for making the desired Nano composite specimens. The strength including
internal bonding (lB), bending strength (modulus of elasticity in bending and modulus of rupture) (MOE, MOR), density,
water absorption and swelling in thickness tests were performed on the specimens. The experimental findings show that the
resultant properties of the new Nano wooden composites are higher compared to witness samples. The results indicated that
increasing the content of Nano-particles had significant effect on the internal bonding as well as bending strength and modulus
of rupture of panels. Increasing the thickness of the panels from 5 to 14 mm improved modulus of bending (47%), internal
bonding (34%) modulus of rupture (27%). The greatest increase in modulus of bending was observed when 1% by weight Nano

resulted in an enhancement in MOR compared to witness samples. The maximum MOR had occurred for samples containing
