Dia(mm) tensile(MPa) Ultimate load(kN) Moudulus of Elasticity 6 **5 *7 ****1 9 **0 *4 ****1 *3 **0 **0 ****1 *6 **5 **2 ****1 *9 **0 **3 ****1 *2 **6 **4 ****1 *5 **0 **6 ****1 *2 **0 **8 ****1 Bolt is widely used in slope engineering, tunnel, and large cave supporting as well as restoration of engineering structure. It can improve the strength and stability of ground, rock mass, and other structures. The traditional steel bolt has some disadvantages, such as easy corrosion, heavy weight, and difficult operation. Glass fiber reinforced polymerï&frac*4;ˆGFRPï&frac*4;‰ is impervious to chloride ion and low pH chemical attack, and its tensile strength is much larger than steel while with lighter weight. Those advantages make it a better alternative in some fields of engineering.
