【摘要】 探讨了超低温胶粘剂的力学性能随温度变化的规律,指出了超低温胶粘剂的两大特点:①其力学性能随温度的降低而出现峰值;②其低温剪切强度受工艺波动的影响很大。论述了超低温胶粘剂在现代航天运载器上的应用状况、特点、工艺和国内超低温胶粘剂在应用过程中所表现出来的一些问题。更多还原

【Abstract】 The regular changes of the mechanical properties of cryogenic adhesives with temperature are researched and two features of the cryogenic adhesives are given out, 1.Peak values come out in the mechanical properties as temperature drops in. 2.The low temperature shear strength is influenced greatly by the processes .The application, feature and technology of the cryogenic adhesives in modern rocket and spacecraft and the problems ap- pearing in the application of the cryogenic adhesives made in China are discussed.更多还原
