中文摘要：

采用硼酚醛树脂（BPR）与普通酚醛树脂（PF）熔融共混挤出制备BPR／PF树脂，通过模压成型工艺制备BPR／PF复合材料。利用热失重（TG）、动态力学性能（DMA）研究不同BPR含量对复合材料热性能、动态力学性能、蠕变和应力松弛性能的影响。结果表明，BPR能显著增强树脂的热性能。700℃，BPR加入质量分数50份时，BPR／PF的残炭率达到了58％，而PF的残炭率只有38．29％，共混复合材料的储能模量提高了28％；玻璃化转变温度提高了18．3℃；复合材料的蠕变和应力松弛性能也得到了提高。

英文摘要：

Boron-containing phenol-formaldehyde/phenol formaldehyde （BPR/PF） resin was prepared by melt blending. BPR/PF composites were prepared through compression molding. The effects of contents of BPR resin on the thermal properties, the dynamic mechanical properties, creep and stress relaxation behavior of the composites were studied by TG and DMA. The results show that BPR can improve thermal properties of the BPR/PF resin. The weight loss of BPR/PF resin is over 58% at 700 ℃ when BPR is 50 phr, while the weight loss of PF is only 38. 29%. Campared with pure PF, the storage modulus of the com- posites increase by 28%. The glass transition temperature of the composites is increased by 18.3 ℃. The behaviors of the stress relaxation and creep of the composities are improved.
