摘要
为提高HS/6高强玻璃纤维复合材料的电绝缘性能以满足Nb_3Sn超导磁体的使用要求,对HS/6高强玻璃纤维进行除碳和表面改性处理。研究发现,经过500℃/4h的除碳工艺后,HS/6高强玻璃纤维表面的碳含量降低了约80%,随后采用质量比为8:100的棕榈酸溶液进行表面改性处理,改性处理后的HS/6高强玻璃纤维表面的碳含量较除碳纤维的提高了26.93%。改性处理后的HS/6高强玻璃纤维的力学性能比仅经过除碳处理的得到了显著提升,其中,拉伸强度提高约10%,层间剪切强度提高约40%,且耐压强度较好,能够满足Nb_(3)Sn超导磁体的使用需求。
The decarbonization and surface modification treatments of HS/6 glass fibers were performed to promote their electrical insulation performance to meet the requirements for use in Nb_(3)Sn superconducting magnets.The results show that the carbon content on the surface of the HS/6 high-strength glass fibers was reduced by approximately 80% after a decarbonization process at 500℃ for 4 hours and the carbon content on the surface of HS/6 high-strength glass fibers,which were treated by palmitic acid with a mass ratio of 8:100 for surface modification after decarburizing,increased by 26.93% compared to that of the decarburized fibers.This modification significantly improved the mechanical properties of the HS/6 high-strength glass fibers more than the decarbonization ones with the tensile strength increased by approximately 10% and interlaminar shear strength improved by about 40%,and their compressive strength was also to meet the requirements for Nb_(3)Sn superconducting magnets.
