Abstract

The result of the suitability study of two wood species as raw material for veneer and plywood are reported. The wood raw material used rubber wood (Hevea   brasiliensis) and sengon (Paraserianthes    falcataria). The wood used were obtained from  different age classes i.e.10  and 20 years for rubber wood and 10 and 15  years for sengon.  The study  consisted of  log peeling  characteristic, veneer properties and some physical-mechanical properties of plywood (triplex and multiplex).All of the logs from two wood species could be peeled in cold condition, producing 1,5 mm veneer at  a cutting  angle between  89o30'-91o30'.  The average shrinkage of veneer is 4.51% and the average veneer swelling from oven-dry to air dry is 3.30 %.The bonding strength of plywood from  all wood species conform with the Indonesian standard,  German standard and Japanese standard for type 11 or water resistant. The spesific gravity and mechanical properties of plywood from  the older tree tends higher than  that from  the younger tree.
