Structural Adhesive used in New F150

Have mentioned this several times...mainly because I keep my vehicles a long time
and each time hear/read of some new vehicle being glued...pay attention...but today
almost all new vehicles are glued together...especially plastic vehicles (carbon fiber)

I'll have to bone up soon, but IIRC from a few decades ago:

Catalyst types (epoxy) and thermal setting continue to age and become brittle
over time. Key is how long is their design life span?

Solvent types continue to have the solvent evaporate to both reduce the volume
and strength of the adhesive

Melted was pretty new to me back then and don't think they use much today, but
will bone up on that

Cyanoacrylate adhesives (super glue) has a huge down side. Shelf life, short
assembly time and low resistance to moisture and heat

Almost all adhesives do not tolerate high temps, O2, O3 and UV well and will
accelerate their aging. Ditto some chem's and/or mixtures of chems.
Even though many are cured or accelerate cure times with UV...

Adhesives are NOT good for peel applications.

My design classes spent much more time with interface fasteners, welding and
'some' adhesives (no where near as good stuff as today)

Am sure they provide higher joint strength when new, but the biggie
for me...what about 10 or more years down the road??

Am also not a fan of aluminum for auto bodies


Oh well, more research and reading for me
