Joint development lamina wood beams of wood acacia (Acacia mangium Willd) and camphor (Dryobalanops spp.,)

Increasing the power of Acacia wood and wood beams Camphor at making lamina based on the concept of deformation. This research is compiled from Acacia wood board sheets and wood Camphor each test sample used as solid beams, beam lamina two layers, beams lamina three layers to gain strength MoE and MoR. Raw material for adhesive laminated beams Dovebond 30 and adhesive Synteko 1909 with Hardener 1999. The nature of physics and mechanics of wood : Testing Results Acacia wood moisture content < of wood Camphor and density, shear strength, MoE, MoRAcacia wood > Camphor wood. Thus, the smaller the value of test results of water content, the density value, the value of the shear strength, the strength values MoE and strength MoR result will be even greater. Beam glued lamina strength: shear adhesion strength of laminated wood beams Camphor using adhesives Dovebond 30 and Synteko 1909 Camphor wood glued have better power, better for the adhesive Dovebond 30 and adhesive Synteko 1909 amounted to 33,95% and 23,09% > beam Acacia wood lamina. Comparison beams lamina two layer and three layer: Camphor Wood, a second beam lamina two layers and three layers of adhesive Dovebond 30 experienced MoE power efficiency of 2,79% ; 16.80% and the second beam lamina two layers and three layers of adhesive Synteko 1909 experience MoE power efficiency of 2,31% ; 11,32% of the strength of a solid beam MoE . And the second beam lamina two layers and three layers of adhesive Dovebond 30 experienced MoR power efficiency of 4,15% ; 4,58% and the second beam lamina two layers of adhesive Synteko 1909 MoR have weakening strength of 4,86% and a triple beam lamina experience MoR power efficiency by 4,58% on the strength of a solid beam MoR. Strength value MoE and MoR best : Strength MoE and MoR number of layers and Camphor wood design Synteko 1909 adhesive layer number for interaction with the design is very significant, then followed by a further test. Value MoE further test the strength of interaction with a number of layers of design occurs in the number of layers of two layers with a design on three layer type 2 the average value of 95.899 kg/cm2 ; 93.299 kg/cm2 and 89.781 kg/cm2. Acacia solid wood beams, beams solid and lamina beams Camphor wood can be used as construction materials in sheltered conditions. The selection of adhesive to provide adhesion value for the type of wood used as a beam lamina. MoE strength values and MoR, plan beam lamina of the type of wood that will be used is to get some references of previous studies. Necessary to study some other type of wood to be used as laminated beams with due regard to the age of the tree and the anatomical structure of the wood.
