Abstract

In recent years, the plywood and veneer industry of Iran has undergone negative growth due to shortage of proper diameter logs and also lack of innovative technologies for the use of low-diameter logs; Moreover, demands for lignocelluloses products has been growing as a consequence of  significant increase in population and expansion of construction Industry, especially in major cities. Hence, it is necessary to cultivate fast-growing species. For this purpose four logs of paulownia (120 cm length and 55 cm diameter) were prepared from the Gorgan shast Kalate forests and then transported to Kosar factory in order to prepare veneers. Produced layers were transferred to the wood laboratory of Gorgan university. Then plywood was manufactured from paulownia species on the basis of the standard 3210 of ISIRI (Institute of Standards and Industrial Researches of Iran) and common tests of plywood were made. The results showed that the mechanical properties of manufactured boards were upper than with standards defined by ISIRI and the physical properties of those manufactured with urea formaldehyde glue were lower than standards which can be considered as negative properties; Albeit, they were not significant and can be disregarded
