The auto industry is new to hybrid FRP/steel parts, but I don't see why they wouldn't work in this application.This article uses data from 1977 - 1996 and a few from 1999, 2002. So 15-45 year old material.
AND this is civil engineering - for bridges, building. Doesn't seem to relevant to me.
Aircraft or Rocket or even transportation vehicles would seem to be much much more relevant, right?
Aluminium and adhesives used a long time in aircraft, right?
side note: expected life for steel reinforced concrete - just 50 years.
problem starts with moisture getting to the steel causing rust. steel to rust is a 50x expansion so you then get cracking and more water and more rust - you get the idea. Add freezing of the water, you know what happens, right? Now if no freezing and in a dry climate (such as parts of California) steel reinforced concrete might make 100 years. Some Roman (not steel reinforced) concrete using very fine volcanic dust to microscopically fill in voids has lasted around 2,000 years.

Granted, that may not be what the a-arms are, but they could be, especially since it's Tesla we're talking about.
