Abstract

Nondestructive evaluation (NDE) technique method using a resonance frequency mode was carried out for woodceramics made by different carbonizing temperature (600, 800, 1000, $1200^{\circ}C$) for Broussonetia kazinoki Sieb. Dynamic modulus of elasticity increased with increasing carbonizing temperature. There was a close relationship of dynamic modulus of elasticity and static bending modulus of elasticity to MOR. Therefore, the dynamic modulus of elasticity using resonance frequency mode is useful as a nondestructive evaluation method for predicting the MOR of woodceramics made by different carbonizing temperature for B. kazinoki Sieb.

공진주파수 모드를 이용하는 비파괴 평가기술법을 닥나무를 소성온도별(600, 800, 1000, $1200^{\circ}C$)로 제조한 우드세라믹에 적용하였다. 공진주파수 및 동적 탄성계수는 소성온도가 증가할수록 증가하였다. 동적 탄성계수 및 정적 휨 탄성계수와 휨강도사이에는 밀접한 상관관계가 나타났다. 따라서 공진 주파수 모드를 사용하는 동적 탄성계수측정은 소성온도에 따라 제조된 우드세라믹의 휨강도를 예측하는 비파괴 평가 방법으로 유용할 것으로 판단된다.
