摘要
以木塑复合材料加工实验为先导,利用弯曲振动方法得到不同工艺条件的木塑复合材料动态弹性模量。选取木粉含量、造粒温度、螺杆转速、偶联剂含量作为影响力学性能指标的主要因素,通过灰色关联分析方法分析不同加工因素对材料力学性能的影响程度。结果表明,木粉含量对木塑复合材料料的弹性模量有显著影响,其次是造粒温度。材料的动态弹性模量随木粉含量的增加而增大;造粒温度在130～140℃范围内,动态弹性模量随温度的升高而增大;在140～150℃时,动态弹性模量呈下降趋势。
Taking wood plastic composite material processing experiment as guide,dynamic elastic modulus under various process conditions could be determined by flexural vibration method.The main factors to influence mechanical performance index were granulation temperature,screw speed,compositions of coupling agent and wood flour content.The influence of different processing factors on the mechanical properties of composites could be analyzed by gray relevant analysis method.The results indicate that wood flour content has a significant impact on elastic modulus,then is granulation temperature.Elastic modulus increases with the increase of wood flour content.When the granulation temperature is between 130~140℃,elastic modulus could increase with the rising of temperature.When the granulation temperature is between 140~150℃,elestic modulus could decrease with the increase of temperature.
