Abstract
The elastic modulus and damping capacity of woodceramics have been investigated on a dynamic mechanical thermal analyzer. The experimental results reveal that the elastic moduli of woodceramics decrease with testing temperature. They are almost independent of vibration frequency, show different variation with strain amplitude for different woodceramics, and increase with sintering temperature.Woodceramics exhibits significant damping gains, especially at room temperature, higher strain amplitude, and higher vibration frequency. The values of damping capacity increase with vibration frequency and strain amplitude, decrease with testing temperature and sintering temperature. Defect damping, including point defect damping, interface damping, and micropores (microcracks) damping, is supposed to be the main contributor to the damping of woodceramics. At elevated temperatures, interface damping is likely to responsible for the majority of the damping of woodceramics.
