Improved heat distortion temperature and low ; temperature impact strength.

提高热变型温度和低温冲击强度.

Dynamic mechanical analysis showed that the heat distortion resistance and the temperature of abrupt drop point for tensile modulus E ′ increased markedly with the irradiation dose.

动态力学分析（DMA）分析表明，聚己内酯辐照交联后的弹性模量和耐热性能显著提高。

Suitable amount of wood powder was also helpful for the increase of composite tensile modulus, flexural property and heat distortion temperature, while it might decrease the impact strength and tensile elongation.

适量木粉能提高复合材料的拉伸模量、弯曲性能和热变形温度，但材料的冲击强度和断裂伸长率有所降低。

The results reveal that introducing bismaleimide into the cured system can improve the heat distortion temperature, flexural strength at high temperature and dielectric properties. In addition the reaction scheme of bismaleimide is mainly the self-polymerization but not copolymerization with epoxy group.
