Adhesive for Cryogenic application

[K.P.M.]

Hello Everyone,

I am looking for an adhesive which can sustain cryogenic temperature range upto (-196°c) to +100°c in vacuum condition.
Bonding material - Aluminium & FRP

Please suggest.

What does "FRP" mean to you. Your answer will inform how easy or difficult it will be to bond to this material.

Aluminum is notoriously difficult to bond to properly for long-term success. Proper surface preparation and chemical pre-treat is necessary. Wiping with a solvent-soaked rag is not good enough.

What are the loads, and in what direction?

What is the part geometry?

It's a really big temperature range, and your materials probably have very different coefficients of thermal expansion.

Even the "perfect adhesive" is likely to fail in an imperfectly engineered joint.

I suggest that you think again about whatever you are trying to accomplish and find a way that does not rely on adhesive.
