In this study, Wheat straw particle boards were produced using a mixture of wheat straw andcotton bolls with Urea formaldehyde resin and its properties were reinforced with nanoclay.Cotton bolls and wheat straw particles were mixed at the ratio of 40:60, 60:40 and 80:20percents, respectively. Nanoclay was used at two levels of 0 and 2 percents based on oven driedweight of resin. Control samples were made of Wheat straw particle. Mechanical and physicalproperties (modulus of rupture, modulus of elasticity, internal bonding, water absorption andthickness swelling after 2 and 24h soaking in water) of the produced boards were measured.The results revealed an increase in cotton bolls in the mixture particles, leads to an increase ofthe bending strength, modulus of rupture and modulus of elasticity of the boards. The resultsalso indicated that water absorption and thickness swelling after 2 and 24h immersion in waterdecreased with increase in nano clay and cotton bolls percents.
