大型推进剂药柱与壳体的粘结研究甚少而这又常常是火箭发动机制造的一个易出故障的方面。把一种柔软的橡胶粘结到刚性的金属壳体上会使应力集中在粘结面上,这就可能使一台已经完工的发动机变成废品。可固化的有粘着力的包复层是一种把推进剂粘结到壳体上常用的中间物。已经得到证实,为了使粘结满意,包复层和推进剂之间必须有化学相似性。本文除了叙述有关各种特殊的化学互相作用而外,还提出了一些使这一概念具体化的粘结系统的例子。 Little research has been done on the adhesion of large propellant grains to the shell, which is often a troublesome aspect of rocket engine construction. Bonding a soft rubber to a rigid metal shell can concentrate stress on the bonding surface, which can turn a finished engine into a scrap. A curable adhesive coating is a commonly used intermediate for adhering propellants to the housing. It has been demonstrated that in order to make the bond satisfactory, there must be chemical similarity between the cladding and the propellant. In addition to describing various specific chemical interactions, this article also presents some examples of bonding systems that embody this concept.
