## Abstract
Abstract Binderless composite plywood has been developed to produce formaldehyde-free composite product. Our previous research has shown that the application of oxidation treatment can be applied in the manufacture of composite plywood without adhesive. Presence of veneer in solid sheet are potentially to complicate in the oxidation process due to the reaction was very affected by accessibility of chemical component of raw materials. The main objective of this study was to determine characteristic of binderless composite plywood of Sengon wood. Variations in the physical and mechanichal properties with respect to veneer layer construction and oxidant composition of veneer and particle were analyzed.. Composite plywood were produced consist of various layers, they were 3, 5, and 7 layers means each type using 2, 3, and 4 veneers layers respectively. There were four oxidant composition between veneer and particles, namely 1 : 3, 1 : 4, 1 : 5 and 1 : 6. The results showed that the differences of composite plywood structure layers affect the characteristics of produced composite plywood. 7-layer structure and 1 : 3 of oxidant composition was the optimum combination to produce composite plywood with the best characteristics.
