薄板类中密度纤维板动静态弹性模量的检测
Measurement of Dynamic and Static Modulus for Thin Medium Density Fiber-Board
摘要
Abstract
This paper aims to quicker test the modulus of the thin wood composites, and developed a new nondestructive test method based on the principle of cantilever-beam bending and vibration.A cantilever beam testing apparatus has been developed to provide a means of dynamic and non-destructive evaluation of modulus of elasticity for small samples of thin wood composites.Five kinds of medium density fiber-board (MDF) were tested, and the testing results demonstrate that there are good linear relationships between the static modulus and the dynamic modulus.关键词
