一些研究工作者指出:固化得不够完全的热固性树脂的热机曲线,由于在测量过程中的进一步固化,使树脂的弹性模量增大而引起形变减少,从而使得在曲线上呈現出一个反常的特征峯。但是当进一步去分析这个現象时,可以发現,在測定的过程中,样品从低温上升到較高的温度,树脂的变形逐渐减少,最后达到与在高温下(200℃)长期热处理(10小时)样品同样的形变值(图1)。因此如果被試样品形变減少,确系 Some investigators have pointed out that the thermomechanical curve of a thermosetting resin that has not been completely cured results in a reduction of deformation due to the increased elastic modulus of the resin due to further solidification during the measurement so that an anomalous characteristic appears on the curve peak. However, when further analyzing the phenomenon, it can be found that during the measurement, the temperature of the sample increases from low temperature to high temperature, the deformation of the resin gradually decreases, and finally the long-term heat treatment at high temperature (200 ° C) ) Sample the same deformation value (Figure 1). Therefore, if the test sample deformation decreases, indeed
