Can anyone point me to very specific info on automotive seat belt manufacturers and their test methods?
I am a polymer engineer and carseat nerd. Recently I had to install a carseat using the seat belt webbing and started to think about a (bad) phenomenon called strain-induced crystallization and polymer relaxation in filaments like nylon and PP from which seatbelt webbing is made. I cannot think of any application of automotive seat belts that would require them to be under high strain for long amounts of time.
(I do not expect a ton of responses but hoped someone here might know and take far less time to weed out the false google leads.)
