摘要
对环氧树腑复合体系化学发泡过程中的压力进行了测试，并利用显微镜对该体系的泡孔形核．长大及定型的发泡行为进行了观察，进而分析了环氯树腑复合材料发泡行为的内在机理。结果表明：当发泡温度在65-95℃区间时，发泡压力是影响泡孔结构参数及材料表观密度的主要因素；而当发泡温度超过95℃，气体的逸散则成为主要影响因泰。
The pressures of chemical foaming process in epoxy composite system was tested, and observed the foaming behavior of cells nucleation, expanding, solidifying and shaping in the foaming system by a microscope. The mechanism of foaming behavior in epoxy foaming composite was investigated. The results show that when the foaming temperature is between 65 and 95℃, the foaming pressure becomes the main factor for the cell structure parameters and material apparent density, and when the foaming temperature exceeds 95℃, the gas dissipation becomes the main effect factor.
