Abstract
In this study, it is aimed to improving core material by using eloxal sludge for production B2 composite panel. Optimal calcine eloxal sludge form was obtained at heat treatment regime with 700 C and 270 minutes. Also it was aimed to investigate possible agglomerate form in the polyurethane. The X-Ray Diffraction (XRD) and particle size analysis were performed to understand detailed structural analysis. The eloxal sludge was respectively doped with different percentage with 15 % and 6 % in the polyurethane for obtaining core material. . B2 composite panels were produced as 1250-1500 mm. The mechanical properties were measurement for different doped of eloxal sludge. The highest mechanical properties was obtained by using 15 % eloxal sludge has a 247 μm when it was observed that surface defects such as air bubbles. Also the thickness of the composite panel was measurement for all samples with 3.8 mm-4.2 mm.
