| 摘 要： | 采用热重分析仪研究了丙烯酸树脂(AR)和粒径不同玻璃纤维/丙烯酸树脂(GF/AR)复合材料的热降解过程,比较了不同粒径的GF对AR复合材料的热稳定性和其热降解过程的影响,并结合扫描电镜表征了其微观形貌。采用Kissinger法和Flynn-Wall-Ozawa法计算了AR和GF/AR复合材料的热降解动力学活化能,并运用Coats-Redfern法确定了AR和GF/AR复合材料对应的热降解反应机理函数。结果表明:AR和GF/AR复合材料呈现出相似的热分解阶段,GF有助于提高材料的热稳定性且与基体结合较好、分散较均匀;通过不同的计算方法获取了相应的活化能并确定了相应的机理函数。

| Abstract: | The thermal degradation process of acrylic resin(AR) and glass fiber/acrylic resin(GF/AR) composites with different particle sizes was studied by thermogravimetric analyzer. The effects of different particle sizes of GF on the thermal stability and thermal degradation process of AR composites were compared. The morphology of AR composites was characterized by scanning electron microscopy. Kissinger method and Flynn-Wall-Ozawa method were used to calculate the thermal degradation kinetic activation energy of AR and GF/AR composites. Coats-Redfern method was used to determine the corresponding thermal degradation reaction mechanism function of AR and GF/AR composites. The results show that AR and GF/AR composites exhibit similar thermal decomposition stages. GF helps to improve the thermal stability of the composites and has good bonding with the matrix and uniform dispersion. The corresponding activation energies are obtained by different calculation methods and the corresponding mechanism functions are determined. |
