The Influence of Aging on the Flexural and Physical Performance of Restructured Bamboo Lumber

Abstract:

In this paper, the restructured bamboo lumber was aged under three kinds of standards (ASTM D1037, BS EN 1087-1, WCAMA) to evaluate its weathering performance. The flexural properties, water absorption and thickness swelling of specimens were tested. The results showed that the retention rates of flexural properties were all more than 70% after three aging treatment. Simultaneously, the growth multiple of 24h water absorption was between 1.05 and 2.54, while those of 24h thickness swelling ranged from 0.06 to 0.38. It was suggested that restructured bamboo lumber could be utilized as outdoor structure material.
