Development on Exterior Composite Plywood (Com-Ply) Product Made of Meranti Veneer and Ekaliptus

Abstract

bonded by Phenol Formaldehyde (PF) and Melamine Formaldehyde (MF) at 10% based on oven dry particle weight and pressed at 30 kgf/cm3 and the temperature 170 0C. Type of wood particle to the core was wafer, made from Ekaliptus (Eucalyptus deglupta Blume) and the face and back layers were Meranti veneers which have 1.5 mm thickness. The results were follows: 1) Physics characteristic for density and MC were fulfill JIS A 5908 ‐ 1994. The value 0.709 ‐ 0.737 grams/cm3 below on target and 9.551 ‐ 10.769 % met the target.2)Unfortunately, physics characteristics for thickness swelling didn't met JIS A 5908 ‐ 1994 standard, because the value was upper from the standard. The value was 7.429 ‐ 15.595 % 3) All of samples for investigation the mechanical properties (Internal Bond, MOE dry & MOR dry) were fulfill the standard, except for width direction Key words: exterior use, Ekaliptus (Eucalyptus deglupta Blume), physics characteristics, mechanical properties.
