Interface compatibility and performance matching between high-rigidity epoxy resin and high-modulus carbon fiber

  • 摘要: 自行开发了一种高刚度环氧树脂(5182树脂),研究了5182树脂的增刚机制、耐热性能和力学性能。结果表明,原位生成的酰亚胺刚性链段及增加的多交联位点提高了5182树脂交联网络的刚性,其玻璃化转变温度达228℃,拉伸模量达到4 375 MPa。采用高刚度5182树脂制备了国产BHM3和东丽M40J高模碳纤维增强高刚度环氧树脂复合材料,考察了高模碳纤维/高刚度环氧树脂单丝复合材料的界面黏结性能和断面微观形貌,并评价了高模碳纤维/高刚度环氧树脂单向复合材料的宏观力学性能。结果表明,由于树脂模量的提高及界面破坏区域由碳纤维表面转移到环氧树脂区,高模碳纤维/高刚度环氧树脂复合材料的界面剪切强度最高达106.8 MPa,宏观力学性能优异,尤其弯曲性能和层间剪切强度大幅提高。
    Abstract: A kind of high-rigidity epoxy resin (5182 resin) was designed and its stiffness enhancement mechanisms in crosslinking network, the heat resistance properties and mechanical properties of epoxy resin were investigated. The results show that the stiffness of crosslinking network of 5182 resin is improved through stiff imide structure and more cross-linked points, the glass transition temperature is 228℃, and tensile modulus reaches 4 375 MPa. High-modulus carbon fiber (Domestic BHM3 and Toray M40J) reinforced high-rigidity 5182 resin composites were prepared, the interface properties, microstructure and the mechanical properties of high-modulus carbon fiber/high-rigidity epoxy resin composites were evaluated. Due to increasing modulus of resin and transferring of interface damage from carbon fiber surface to the resin area, high modulus carbon fiber/high-rigidity epoxy composites shows the highest interfacial shear strength (106.8 MPa) and excellent mechanical performance, especially flexible properties and interlaminar shear strength.
