Influence of Lamina Wood on the Physical Properties, the Nature of Mechanics, the Strong Class on the Combination of Sengon Wood and Merbau Wood

Abstract

Wood is a material used by man to meet his life needs, both as building materials and other tools. Conditions as a construction component require large size, one that can be by making lamina wood. This study is the influence of lamina on physical properties, mechanical properties, healthy classes using MUF adhesives, which can provide knowledge, so it is utilized as an alternative to solid wood. Deutsches Institut for Normung Standard (DIN) 52186. The value of lamina wood content is between 21.19% to 12.43%, density value between 0.58 g/cm3 to 0.73 g/cm3, lamina wood shear strength between 3.1 N/cm2 to 6.4 N/cm2, MOE between 6192 N/cm2 to 13275 N/cm2, MOR between 51 N/cm2 to 85 N/cm2. Diversity analysis shows that the combination of wood type factor (A) and layer count factor (B) significantly affects MOE diversity analysis of 100.93 very significant and 16.77 very significant. For (MOR) significant influences of 5.66 significant and 7.07 significant. In contrast, adhesive and shear strength significantly affect diversity analysis of 11.71 very significant and 9.03 very significant. Merbau wood as face/back and Sengon wood as core (layer 3 and 5) can be classified as strong grade II-III. For Modulus Of Rupture (MOR) on the treatment of Sengon wood as face/back and Merbau wood as core (3 and 5) as well as Merbau wood as face/end and Sengon wood as meat (3 and 5) can be classified into strong grades II-III.
