Enhancement in Mechanical Properties of Bamboo by Press Forming

Abstract:

Article Preview

Raw Japanese timber bamboo was hot-pressed in order to investigate its static and dynamic mechanical properties such as flexural strength, flexural modulus, and impact strength. The purpose of this work was to examine the effect of molding pressure on the mechanical properties of hot-pressed bamboo. The hot-pressing pressures used were varied from 5 to 100 MPa and hot-pressing temperature was fixed to be 160°C. The density, flexural strength and flexural modulus remarkably increased up to 20 MPa, and then gradually increased. However Izod impact strength showed different pressure dependence. In conclusion, remarkable densification both in vascular bundles parts and parenchyma parts was achieved after hot-pressing of bamboo resulting in the increase in density and mechanical properties.
