通过对发动机机体复合材料的疲劳试验,研究了短纤维热压成型工艺研制的玻纤/酚醛环氧机体材料的疲劳损伤和疲劳寿命,为发动机机体的复合材料设计和结构设计提供有价值的实验基础。

Polyetherimide (PEI) was used to improve the brittleness of bisphenol A dicyanate- epoxy novolac resin blends. Inclusion of 15% PEI led to a 115% (mass fraction) increase of the fracture toughness (KIC) and slight increase in flexural strength with retention in flexural modulus compared to those of the unmodified cured blends. The microstrucures of the modified resins were examined by scanning electron microscopy and dynamic viscoelastic analysis. It was observed that the dichloromethane absorption of the...

Polyetherimide (PEI) was used to improve the brittleness of bisphenol A dicyanate- epoxy novolac resin blends. Inclusion of 15% PEI led to a 115% (mass fraction) increase of the fracture toughness (KIC) and slight increase in flexural strength with retention in flexural modulus compared to those of the unmodified cured blends. The microstrucures of the modified resins were examined by scanning electron microscopy and dynamic viscoelastic analysis. It was observed that the dichloromethane absorption of the modified resin with co-continuous phases structure increased significantly compared to the unmodified cured blends. The toughening improvement and the solvent resistance properties were correlated to the morphology of the modified blends. The cure schedules had no practical influence on the fracture toughness and morphologies of the blend incorporating 10% PEI modifier.

采用聚醚酰亚胺以提高双酚A二氰酸酯/酚醛环氧树脂共混物的断裂韧性.实验结果表明,聚醚酰亚胺是氰酸酯/酚醛环氧树脂共混物的有效增韧剂,加入15%的聚醚酰亚胺可使断裂韧性(KIC)提高到145MPa·m0.5,弯曲强度也有所提高.用扫描电子显微镜和动态粘弹谱研究了改性共混物的微观结构,具有双连续结构的共混物的耐溶剂性能大大下降,共混物的韧性和耐溶剂性主要与相行为有关, 固化工艺对含10%聚醚酰亚胺的共混物的断裂韧性和形态没有明显的作用.

Uncatalyzed blends of bisphenol A dicyanate ester/epoxy novolac with different molar ratios were prepared. Hydrothermal ageing for times up to one month was performed and water take up profiles of those blends were determined by a gravimetric method. It was found that the blends absorbed much less water than homopolycyanate when the molar fractions of the cyanate group in the blends were greater than 0.5. Dynamic mechanical analysis and FTIR determination were performed on virgin and aged samples. The results...

Uncatalyzed blends of bisphenol A dicyanate ester/epoxy novolac with different molar ratios were prepared. Hydrothermal ageing for times up to one month was performed and water take up profiles of those blends were determined by a gravimetric method. It was found that the blends absorbed much less water than homopolycyanate when the molar fractions of the cyanate group in the blends were greater than 0.5. Dynamic mechanical analysis and FTIR determination were performed on virgin and aged samples. The results demonstrate that the hydrothermal ageing resistance of the blends is superior to that of homopolycyanate.

制备了不同摩尔比的双酚 A二氰酸酯 /酚醛环氧树脂共混物 ,测定了共混物和纯氰酸酯聚合物的吸湿曲线 ,用 DMA和 FTIR研究了湿热老化前后共混物结构与性能的变化。结果表明 ,氰酸酯基摩尔分数大于 0 .5的共混物具有明显比聚氰脲酸酯更低的平衡吸湿。老化后共混物的玻璃化转变温度保持率随氰酸酯含量的增加而降低。老化后聚氰脲酸酯的 FTIR谱出现了降解产物的吸收峰 ,而共混物没有出现明显的结构变化
