摘要
利用DMA分析技术考察了玻纤增强酚醛复合材料的储能模量在升温过程中的变化。由于后固化和热分解反应的发生,材料的储能模量在温度高于玻璃化转变温度后出现了先上升随后下降的趋势。以三元件标准线性固态模型为基础建立了材料储能模量变化的数学模型,模型计算值与实验实测值吻合较好。
A typical glass transition of the crosslinked thermoset polymer was followed by irreversible postcured and degradation reactions, which were exhibited by the increasing storage modulus. Using an analogy to the standard linear solid （SLS） model, a storage modulus modeling methodology was developed to characterize the temperature-dependent complex moduli of glass fiber reinforced phenolic materials. The calculated storage modulus of glass fiber reinforced phenolic materials by the model agreed well with the experimental data.
