摘要
为研制高结构效率的复合材料气瓶,采用T700碳纤维/环氧树脂体系在薄壁铝金属内衬上缠绕成型复合气瓶,对其进行了水压自紧试验,100次0～36MPa水压疲劳试验以及水压爆破试验,并且采用声发射、应变测试等方法对试验过程进行检测。结果表明,经过水压自紧试验后复合材料气瓶具有较好的疲劳性能,100次疲劳对气瓶的损伤较少,并且经过疲劳后的气瓶爆破压强仍然达到88MPa,具有较高的结构效率。
With the aim of developing a composite pressure vessel with the exceptional Structural Efficiency,the fiber winding method was carried out with the Epoxy resin/T700 carbon fiber system as composited component.Hydraulic pressure,burst pressure,100 times fatigue testing,and acoustic emission were employed to estimate the properties of the composite pressure vessel.Besides,the results indicate that the composite pressure vessel with the hydraulic pressure treatment shows the better fatigue property and the less damage under the 100 times fatigue testing.Meanwhile,its burst pressure can still be kept at 88 MPa with a excellent structural efficiency.
