玻璃钢锚杆是一种由复合材料制成的锚杆。从20世纪80年代开始,为了使煤巷锚杆具有可切割性能,降低锚杆支护成本,国内外采矿技术发达的国家积极探索在煤帮锚杆中采用新型材料代替钢锚杆,其中高分子复合材料,特别是树脂基体复合材料是主要的攻关方向。90年代初,前苏联的劳动保护与安全管理局和矿山管理局立项,试制以玻璃纤维为增强材料的绞合式聚合材料锚杆,1991年生产第一批并进行了井下工业性试验;瑞士 Weidmann 公司成功地推出了全螺纹锚杆、注浆锚杆和全螺纹锚索,并在矿山、隧道工程
FRP bolt is a bolt made of composite materials. From the 1980s onwards, in order to make the coal gateway bolt has the cutting performance and reduce the cost of bolt support, the developed countries at home and abroad have actively explored the use of new-style materials in the coal-gang bolt to replace the steel bolt, of which the high Molecular composite materials, especially resin matrix composites is the main research direction. The early 90s, the former Soviet Union’s Bureau of Labor Protection and Safety and the Mines Authority to project, trial production of fiberglass reinforced materials stranded polymer anchor bolt, the first production in 1991 and carried out downhole industrial test; Switzerland Weidmann The company has successfully launched a full-threaded bolt, grouting bolt and full-threaded anchor, and mine, tunnel engineering
