摘要
将偶联剂改性的氧化石墨烯(GO)添加到酚醛树脂中,制备了GO改性的玄武岩织物/酚醛树脂复合材料板材。采用三点弯曲、短梁剪切和落锤冲击试验方法,研究了GO的含量对复合材料弯曲性能、层间剪切强度(ILSS)和冲击性能的影响。结果表明,GO的加入显著提高了玄武岩织物/酚醛树脂复合材料的力学性能,随着GO含量的增加,复合材料的力学性能先增大后减小;相对于空白样,当GO的含量为2wt%时,弯曲强度和弯曲模量分别提高了39%和25%;ILSS提高了43%;当GO的含量为1wt%时,冲击破坏载荷增加40%,破坏吸收能量增加60%。
The coupling agent modified graphene oxide（GO）was added into phenolic resin to prepare basalt fabric reinforced phenolic composites.The influence of graphene oxide mass fraction on the mechanical and impact properties of basalt fabric reinforced phenolic composites was investigated.The results show that the addition of GO increases the flexural strength,modulus and interlaminar strength（ILSS）of the basalt fabric reinforced phenolic composites.The maximum flexural strength and modulus are obtained at the GO mass fraction of 2 wt%,which is increased by nearly 39% and 25%,respectively.The maximu mimpact load and damage absorbed energy increase by 40% and 60%,respectively,after adding 1 wt% GO.
