Adhesives to bond different component are widely used within Science missions. These adhesives are required to maintain a certain level of reliability with respect to the environmental factors that have an influence on their properties and thus functionality. The behaviour of such adhesives in cryogenic condition needs to be clearly understood and quantified to increase design reliability and optimize their use. The commonly used approach of extrapolation of room temperature performance measurement is not necessarily valid and moreover, the available data of adhesive behaviour in cryogenic conditions is limited. In view of long term operation in cryogenic condition like for deep space missions, L2 missions or other specific missions (i.e. JUICE), a better prediction and understanding of adhesive bond properties is needed. The activity will consist of the following: 1)Literature review: – related to the type of adhesive/substrate combination used in space and/or for cryogenic application – related to the existing data for adhesive bond behaviour in cryogenic environment 2)Selection/Trade-off of the most representative adhesive/substrate combination that can be used in cryogenic condition for space missions. 3) Definition of a test plan to evaluate, quantify and predict the change in the adhesive bond property in cryogenic condition. This test plan should focus on the characterization of relevant parameters.4)Carry out the agreed test plan 5)Produce a test report that compile all quantified data as function of the adhesive/substrate type and the chosen investigated parameter. This document shall be used as reliable database (i.e. Handbook) for future application. 6)Propose a model to evaluate adhesive bond reliability in time in cryogenic condition as function of the adhesive/substrate combination.
