EVALUATION OF THE MACHINABILITY AND FINISHING OF ACACIA MANGIUM VENEER - BASED COMPOSITE

Abstract

This paper evaluated the machinability and finishing of acacia mangium veneer - based composite (VBC) using the 3-dimensional pressing machine. The results showed that the VBC composite has relatively good machining properties (equivalent to group 4 wood), reaching requirements in the production of material for construction and interior joinery, with relatively smooth surface quality after sawing; good drilling ability, deformation of drill hole after 24 hours is quite small; the screw adhesion strength of VCB was 1.3 times higher than that of Acacia wood. The results of evaluating the finishing ability of VBC showed that the surface of wooden structures decorated with Polyurethane paint and Inchem paint had a good quality. Overall, Inchem paint had better paint film quality than that of Polyurethane paint. The results of this research are the basis for determining methods of processing and decorating VCB components used in construction and furniture.
