摘要/Abstract

摘要： 设计了一种玻璃钢材料锚环的矿用锚索支护结构并设计了玻璃钢锚环的制作流程,应用湿法缠绕成型工艺进行了锚环的制作。对所制锚环进行了压载试验和张拉试验。研究表明无碱玻璃纤维缠绕成型的196^#不饱和聚酯树脂基玻璃钢锚环具有质量轻、易成型、耐酸碱腐蚀性能好等优点。玻璃钢锚环的承压性能在500kN以上,张拉强度极限为464kN。

Abstract: For a long period, anchor ring in supporting system used metal as its producing material. Coal road has a moist and corrosive situation, which may cause the pyramidal faces of anchor ring and clips to rust and even lose work. When rock faces has the tendency of motion, the clips and anchor ring will not bite well due to the increase of friction coefficient in contact area. The corrosion problem has been influencing the safety problem and durability of permanent anchor supporting system. Glass Fiber Reinforced Plastics (GFRP) is a kind of material which composited by high-strength and low-density glass fiber material and hardener. GFRP has the properties of high strength of extension and low shear strength. For acid and alkali resistance and its outstanding mechanics properties, it has been used increasingly in anchor supporting system. In this paper, we designed a glass fiber reinforced plastics anchor ring in supporting structure of mining anchor and its production process of wet winding forming. After the period of production, loading test and tensile test were conducted on the produced anchor ring. The pressure-bearing capacity of GFRP anchor ring is more than 500kN and the ultimate tensile strength is 464kN. According to the results, unsaturated polyester resin anchor ring which is made of alkali-free glass fiber and made through filament winding has the advantages of light quality, easily forming, acid and alkali resistance, etc.

Key words: glass fiber reinforced plastics, anchor ring, filament winding, supporting structure
