摘　　要：为改进酚醛固化环氧树脂复合材料的性能,合成了邻甲苯酚醛树脂(o-CFR)、邻甲酚醛环氧树脂(o-CFER)和氧化石墨烯(GO),制备了o-CFR/o-CFER/GO玻璃钢复合材料,研究了不同含量的氧化石墨烯对复合材料物理力学性能的影响。结果表明,GO加入可以改善材料的力学性能、耐热性能和电绝缘性能。当酚醛与环氧质量比为4∶6,材料中加入1.2%的GO时,起始分解温度(Tid)提高了91℃,复合材料的拉伸强度和冲击强度分别提高了102%和86%;加入2.0%时材料玻璃化转变温度(Tg)可提高19℃。In order to improve performance of phenol formaldehyde resin curing epoxy resin,the o-cresol formaldehyde resin（o-CFR）,o-cresol formaldehyde epoxy resin（o-CFER）and graphene oxide（GO）were synthesized and used to prepare o-CFR/o-CFER/GO fiberglass reinforced composites.The physical and mechanical properties of the composites with different contents of the GO were investigated.The results show that the GO could improve the thermal,mechanical and dielectric properties of the composites.When the mass ratio of oCFR/o-CFER is 4∶6,the content of GO is 1.2%,the initial degradation temperature Tidincreases about 91℃,and the glass transition temperature Tgincreases 19℃ with the GO content of 2.0%.When the content of GO is 1.2%,the tensile strength and impact strength of the composites are enhanced about 102% and 86%,respectively.
