111 Evaluation of Elastic Characteristic of Bamboo by Ultrasonic Method

Abstract

Bamboo is a typical composite and natural, functionally graded materials. Especially, the bamboo fiber plays an important role to generate a superior elastic characteristics of bamboo. The tensle tests have been applied to obtain the elastic properties of the bamboo fiber. 0n the other hand ultrasound technique is available to obtain it nondestructively. This study focuses on the measurements of its elastic property. It is concluded that using a mixed principle anisotropic elastic property of the bamboo fiber can be obtained effectively.
