Abstract

The invention discloses a manufacturing method of a whisker enhancement type fiberglass full thread roof bolt, wherein the technical process comprises the following steps: yarn supplying, resin pickup, hot briquetting, heat preservation, step cooling, dragging and cutting. The manufacturing method can overcome the defects that the traditional fiberglass full thread roof bolt has poor surface finishment, serious abrasion for equipment, poor toughness, poor fatigue resistance, poor chemical resistance, poor humidity resistance and is easy to absorb water.

Description

technical field [0001] The invention relates to a method for manufacturing a whisker-reinforced glass fiber fully threaded anchor rod. Background technique [0002] Fiber-reinforced plastic bolts have the advantages of high specific strength, good safety, corrosion resistance, strong designability, and convenient construction, and are mostly used for coal mine roadway support. With the development of science and technology, bolts are not only used in mines, but also in engineering technology, which can actively reinforce slopes, tunnels and dams. It is used more and more widely. [0003] However, due to the poor surface finish of the fiber reinforced plastic anchors currently on the market, there are many burrs on the surface of the anchors. If you do not wear gloves, it is easy to scratch your hands. wear and tear. Due to the immature formula of fiber-reinforced plastic bolts, the produced bolts have the disadvantages of poor toughness, poor fatigue resistance, poor chem...
