Abstract
[Purposes]This paper studies the application of glass fiber reinforced epoxy resin composites in the field of insulating rod.[Methods]Using 7628 glass fiber fabric as the reinforcing material and bi-sphenol A epoxy resin as the matrix,epoxy glass fiber composites were prepared.The electrical,mechani-cal and thermodynamic properties of the composites were tested.Based on the experimental results,the performance characteristics of the composites were analyzed and compared with the performance param-eters of product materials for the insulating rod.[Findings]The 7628 glass fiber reinforced epoxy resin composite material can achieve a tensile strength of 583 MPa,a flexural strength of 570 MPa,a shear strength of 53 MPa,a breakdown voltage greater than 100 kV,a glass transition temperature of 106℃,and a linear expansion coefficient of only 6.84×10-6.The insulating rod product has a tensile failure strength of 149 kN,a mechanical performance margin of 1.5 times,and has passed the 1.2 times light-ning impulse margin test.[Conclusions]This composite material exhibits exceptional mechanical proper-ties,electrical breakdown strength,and thermodynamic stability,not only ensuring the stability and dura-bility of the insulating rod but also enhancing their reliability and safety in complex environments,which presents promising application prospects in the field of insulating rod.
