Hi all,

I would like to qualify our bonding process for the heaters that are going to remain permanently attached on a Spacecraft.

I am trying to calculate an Acceleration Factor for the adhesive (Scotchweld 3M). Currently I am guessing a Coffin-Manson exponent of 6 but I am not convinced if it is conservative enough.

Do you have some value or some reference to suggest?

Franck
