摘要
结合压力容器缠绕成型工艺,研究了电子束固化树脂体系的工艺性能、固化参数及力、热性能;在国内首次采用电子束固化技术制备了T700碳纤维复合材料压力容器并通过水压试验验证。试验结果表明:电子束固化环氧体系(EB-1)具有较好的工艺性能和力学性能,耐热性能优良,达到191. 4℃;采用电子束固化工艺制备的T700碳纤维/EB-1复合材料NOL环的拉伸强度为2020 MPa,层间剪切强度为68. 9 MPa;制备的150 mm压力容器的特性系数PV/Wc为44 km,达到了目前同类热固化复合材料的水平,固化周期仅为热固化复合材料的1/15。
The processing property, curing parameter, mechanical property and heat-resisting property of electron-beam cured resin systerm were investigated which were combined with the winding-forming process of pressure vessel. The pressure vessel of T700 carbon fibre composite material was prepared firstly with the adoption of electron beam curing technology interiorly which passed the hydroburst pressure experimental verification. The result of expriment indicates that the electron-beam cured expoxy system (EB-1) possesses better processing property and mechanical property. Its heat-resistant quality is excellent and up to 191.4 ℃. The tensile strength of NOL ring is 2020 MPa, which is made of T700 carbon fibre/EB-1 composite material cured with electron beam, and its interlaminar shear strength is 68.9 MPa;The characterization factor ( PV/W c) of the prepared Ф150 mm pressure vessel has reached 44 km which currently achieved the level of the same type of thermo-curing composite material, while the cure period is only the 1/15 of thermo-curing composite material.
