摘要:
为满足液氧/煤油火箭发动机所用材料相容性要求,采用浸泡法对由3种胶黏剂(DW-1低温胶、DW-3低温胶、J-249胶)组成的铝合金2219/聚甲基丙烯酰亚胺(PMI)黏接件和PMI/PMI黏接件分别与石油基、煤基航天煤油的相容性展开研究。通过将所得胶接件置于-60～50 ℃温度下的两种航天煤油中进行浸泡,并对浸泡后的胶黏件进行拉伸性能测试,结果表明:3种胶在经-60～50 ℃温度范围内的两种航天煤油浸泡处理后,仍可对胶接件进行有效胶接,且DW-1和DW-3胶在低温环境下的表现更优,高温环境会导致DW-1胶与合金2219胶接界面有一定程度的弱化,而J-249胶与煤基航天煤油表现出较好的适应性。
Abstract:
To meet the compatibility requirements of materials used in liquid oxygen/kerosene rocket engines, a comparative experimental study was conducted by the soaking method on the compatibility of aluminum alloy 2219/polymethacrylimide(PMI)bonding specimens and PMI/PMI bonding specimens with petroleum based and coal based aerospace kerosene, respectively, which are composed of three adhesives(DW-1 low-temperature adhesive, DW-3 low-temperature adhesive, J-249 adhesive). The obtained bonding specimens were soaked in two types of aerospace kerosene at -60-50 ℃, and the tensile performance on the soaked bonding specimens were tested. The results show that the three adhesives can still effectively bond the bonding specimens after being soaked in two types of aerospace kerosene within the temperature range of -60-50 ℃, and the DW-1 and DW-3 adhesives perform better in low temperature environment. The high temperature environment will weaken the interface between DW-1 adhesive and alloy 2219, while J-249 adhesive and coal-based aerospace kerosene show better adaptability.
