Abstract:
This paper aims to quicker test the modulus of the thin wood composites, and developed a new non-destructive 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.
Key words: cantilever-beam vibration, cantilever-beam bending, dynamic modulus, static modulus
