Flexural strength properties of glulam made from combining of sago bark and two wood species from West Papua

Abstract

This paper describes the prospect of producing sago bark-glulam in combination with two less used wood species. In total 51 glulam, 17-combined layers with three replications, were tested for flexural strength, density, and delamination. The results show that laminating increased the density compared to that of the original material. Plain sago bark has higher MOR and MOE than when it is combined with the two other species into glulam, with reductions of 8.2 and 43.9%, respectively. Delamination mostly occurred following 24 h of water immersion for the glulam of sago bark and its combinations, but it was absent in glulam with- out sago bark
