摘要 分别以环保型PF(酚醛树脂)和萘酚改性环保型PF为母体,成功合成了烯丙基化PF和萘酚改性烯丙基化PF,并制备了萘酚改性烯丙基化PF/BMI(双马来酰亚胺)共聚树脂;然后分别以上述树脂作为基体树脂,制备了玻璃纤维增强型复合材料。结果表明:当基体树脂为萘酚改性烯丙基化PF/BMI共聚树脂时,相应复合材料的冲击强度(321.6 kJ/m2)和弯曲强度(524.1 MPa)比萘酚改性烯丙基化PF基复合材料提高了11.0%和46.3%,比未改性环保型烯丙基化PF基复合材料提高了42.8%和258.2%,说明萘酚改性烯丙基化PF/BMI共聚树脂的增韧效果优于萘酚改性烯丙基化PF;萘酚改性烯丙基化PF/BMI共聚树脂基复合材料的耐热性能优于未改性烯丙基化PF体系,这是因为前者800℃时的残炭率(39.62%)高于后者(10.92%)所致。 With environment-fi-iendly PF(phenolic resin) and PF-0 (environment-friendly PF modified by naphthol) as matrix materials respectively, so the PF with allyl and PF-1 (PF with allyl modified by naphthol) were successfully synthetized,then a PF-l/BMI(bismaleimide) copolymer resin was prepared. Finally a series of composites reinforced by glass fiber were prepared by above these resins as matrix resins respectively. The results showed that the toughening effect of PF-1 was lower than that of PF-1/BMI copolymer resin because the impact strength(321.6 kJ/m2) and flexural strength(524.1 MPa) of the composites with PF-1/BMI copolymer resin as matrix resin were 11.0% and 46.3% more than those with PF-1 as matrix resin,or were 42.8% and 258.2% more than those with unmodified environment-friendly PF with allyl as matrix resin. The heat resistance of the composites with PF-1/BMI copolymer resin as matrix resin was better than that with unmodified PF with allyl as matrix resin because the residual carbon of the former(39.62%)was higher than that of the latter(10.92%) at 800℃.
