Shahid Beheshti University Advanced Environmental Sciences 3115-7173 6 2 2008 12 21 Study on the Possibility of WPC Production with Sawdust and Poly Ethylene Terephthalate Residues Study on the Possibility of WPC Production with Sawdust and Poly Ethylene Terephthalate Residues 95462 FA Mohammad Ghofrani Department of Wood Industires, Faculty of Civil Engineering, Shahid Rajaee Teacher Training University Journal Article 2015 05 17 The present study has been done to find a suitable way to produce Wood-Plastic Composites (WPC) from Polyethylene terephthalate (PET) in accordance with the specifications mentioned in the National Standard of Iran. The experimental samples were prepared with 45 x 45 cm area; in 5, 10, and 16 mm thickness; 0.8 gr/cm2 density; altering weight proportions between % 20 to 49 of residual PET based on the total weight of the samples; using hot press method and these factored were as follows: Modulus of rupture (MOR); Internal Bond (IB) in vertical direction to the surface of samples; Swelling; Water adsorption after 2 and 24 hours submersion in water. The outcome of the present study proves that there is a good possibility to produce Wood-Plastic Composites with different thicknesses from PET residuals in 200 degrees centigrade under 3 min hot press; we achieved producing layered boards of 5 mm thickness, having %20 residual PET, %10 Poly-ethylene, and %70 saw-dust, in compliance with the above mentioned standard The present study has been done to find a suitable way to produce Wood-Plastic Composites (WPC) from Polyethylene terephthalate (PET) in accordance with the specifications mentioned in the National Standard of Iran.
