摘要
以两种φ120 mm含钢内衬增强纤维缠绕筒为研究对象(一种为纯玻璃纤维缠绕筒,另一种为玻、碳纤维混合缠绕筒),进行落锤冲击试验、三点弯曲试验和悬臂弯曲试验,研究这两种含钢内衬的不同纤维缠绕筒在横向低速冲击下的抗冲击性能。对比试验表明,玻、碳混合缠绕筒的整体刚度比纯玻璃纤维缠绕筒高。悬臂弯曲试验中纯玻璃纤维缠绕筒和玻、碳混合缠绕筒的钢内衬主应力随载荷的变化率分别为64.39 MPa/kN和79.77 MPa/kN,表明玻、碳混合缠绕筒的钢内衬对外载荷更为敏感,钢内衬的抗冲击能力下降。
Two kinds of φ120 mm reinforced fiber winding canisters with steel lining were studied.One kind canister is glass fiber winding tube,the other is glass and carbon winding tube.By series of tests,including drop hammer impact test,three-point bending test and cantilever bending test,their impact resistance under transverse low-velocity impact was studied.It is shown that the whole stiffness of glass and carbon winding canister is higher than that of pure glass fiber winding canister.Their ratio between the first principal stress of steel lining and load increment are 64.39 MPa/kN and 79.77 MPa/kN respectively in cantilever bending test,showing that glass and carbon winding canister is more sensitive to external load,so its impact resistant of steel lining declines.
