摘要/Abstract

摘要： 针对高强度复合材料锚杆拉挤成型的应用需求，开发了酸酐固化环氧树脂基体。研究了树脂基体的流变性能、固化性能和浇注体力学性能，并建立了Arrhenius粘度模型来预测树脂的粘度特性。结果表明，开发的环氧树脂基体具有粘度低、工艺操作期长、固化反应放热集中等优点，树脂浇注体的拉伸强度、断裂伸长率、弯曲强度分别达到了74.25 MPa、4.48%、127 MPa，性能满足高强度复合材料锚杆拉挤生产工艺及性能要求。实验选取高强度玻璃纤维拉挤成型制备了直径22 mm的全螺纹复合材料锚杆，杆体的拉伸强度、横向剪切强度分别达到了1027.3 MPa、223.6 MPa，符合高强度复合材料锚杆要求。

Abstract: In order to meet the application requirements of high strength composite rock bolt pultrusion molding, epoxy resin matrix cured by acid anhydride was developed. The rheological properties, curing properties of the resin matrix and mechanical properties of the casting body were studied, and the Arrhenius viscosity model was established to predict the viscosity characteristics of the resin. The results showed that the developed epoxy resin matrix has the advantages of low viscosity, long operation period and concentrated heat release in curing reaction. The tensile strength, elongation at break and bending strength of resin castable are 74.25 MPa, 4.48% and 127 MPa, respectively, which meet the requirements of high strength composite bolt pultrusion production process and performance. In addition, high strength glass fiber was selected to prepare 22 mm diameter full thread composite bolt, the tensile strength and transverse shear strength of bolt body reached 1027.3 MPa and 223.6 MPa, respectively, which meet the requirements of high strength composite rock bolt.
