对木材-废弃塑料复合材的制造工艺进行了研究,并探讨了利用无损检测方法对其动态杨氏模量进行检测的可行性.研究发现,木材-废弃塑料复合材可以在155 ℃、1MPa和7min的热压条件下制得,其动态杨氏模量可以由无损检测方法测量.利用纵波传播法测得的动态杨氏模量值大于纵向共振法和弯曲振动法测得的结果;利用面内弯曲振动法测得的动态杨氏模量值小于面外弯曲振动法测得的结果.

Manufacture technology of wood / waste styrofoam composite was investigated. The possibility that the dynamic Young's modulus of wood / waste styrofoam composite can be measured by nondestructive testing method was also discussed. The following conclusions have been drawn. Wood / waste styrofoam composite can be manufactured under the hot press condition of 155℃, 1MPa for 7 minutes. The dynamic Young's moduli measured by longitudinal transmission method were bigger than those measured by longitudinal vibration method and flexural vibration test. The dynamic Young's moduli measured by in-plane flexural vibration test were less than those measured by out-plane flexural vibration test.
