CRES installed on CFRP
CRES installed on CFRP
(OP)
Why is the industry standard in aerospace to not intall CRES (15-5PH, AISI 301, or otherwise) on CFRP. I realize that the materials have significantly different modulas of elasticity and would strain differently, therefore it would not be suggested for doublers and or large fittings, but I can not see the rational for small clips and stiffeners, etc. I see aluminum details installed on 777 floor beams all the time, and it has a much higher coefficient of thermal expansion, so it can't be for that (CRES is actually quite close to Titanium which I understand is very similar to CFRP for modulus and coefficient of thermal expansion). Any advice on this subject would be appreciated.

Perhaps it is because CRES is heavy?

Be careful with conclusions that certain materials corrosion wise go together. Most CFRP panels has an extra glass layer on the outside between a bracket and the panel. Fasteners which holes are drilled through the panel are a different story.............
