摘要
采用高强芳纶Ⅱ和凯芙拉-49纤维及不锈钢内衬,研制出小型球形环氧树脂基纤维复合材料压力容器。主要介绍了容器的结构材料、设计、试验方法。通过容器的密封性检验及贮存前后的液压爆破试验,结果表明,容器的设计是成功的,满足了设计使用要求。与同类钢制压力容器相比,在内径、外径、工作压力、安全系数相同情况下,该复合材料容器质量可减轻60%以上,漏率小于1×10-8Pa.m3/s,且贮存3年后爆破压力不会下降并略有提高。
By using high strength aramid fibre 11 and kevlar -49 fibre and stainlesssteel liner, one small spherical epoxy resin matrix fibre composite pressure vessel is developed. The structure material, design and testing methods of the vessel are introduced. Through pressure tests and hydrostatic pressure blast tests of the composite vessel before storage and after storage, the results show that design of the vessel is successful, and it can meet the requirement for use in a certain product. The weight of the composite vessel is over 60% lighter than that of the same kind of steel pressure vessel when the inner and outer diameter, work pressure and safety coefficient are same. The veak rate is lower than 1 × 10^-8 Pa · m^3/s. After three years＇ storage of definite environment, the blast pressure goes a little higher instead of decreasing.
