In this paper, active groups terminated silicane was used to react with the hydroxyls of bisphenol A epoxy resins, that introduced organic silicon without consuming epoxy groups. This modifying process improved the combining degree of the cured resin, so both the toughness and the other characters (as strength, thermal resistance) were all could be improved.
为此本论文采用国内外文献中尚未见报道的、带活性基团的有机硅来改性双酚A型环氧树脂,通过端基基团与环氧链上的羟基反应生成大键能的Si-O键的方式来引进有机硅,改性过程中不仅不消耗环氧基,并且还提高了树脂固化物的交联密度,所以既能增韧树脂,又能提高其耐热、耐冲击等各项性能。

Grain boundary slidings happen in this alloy at the creep temperature of 200 ℃ and the deformation of this alloy is coordinated by intragranular slip and grain boundary sliding.
结果表明:在125~200 ℃蠕变温度下,当蠕变寿命接近100 h时,2024铝合金的蠕变应力随着温度的升高明显下降;与125 ℃相比,150 ℃时合金的蠕变应力下降9.3%,在175 ℃时合金的蠕变应力下降30.3%;当蠕变温度为200 ℃时,该合金的蠕变应力下降幅度达到45.8%;在125~175 ℃下,合金在蠕变过程中的变形机制主要为位错在晶内的滑移;在200℃时,合金晶界开始发生滑移,合金变形由晶界滑移与位错在晶内的滑移协调完成;在合金蠕变断面上存在大量微孔,随着蠕变温度的升高,微孔的尺寸明显变大,当微孔尺寸超过3 μm时,微孔对合金的断裂机制有显著影响;在125和150 ℃下,合金的蠕变断口呈现韧窝型穿晶断裂特征;在175和200 ℃下,合金的蠕变断口呈现沿晶断裂特征。
