not at all. possibly the greatest thing you can do if that's your
desire is go to a junk yard. there' you'll see all kinds of componentry
disassembled so you can see pretty much exactly how it all works. i
think they're amazing places.

The fabric helps to minimize elongation of the belt while, as I believe the
fabric is actually highly drawn fibers or monofilaments with high tensile
and minimal elongation properties.

Embedding these in the belt cross section adds strength and minimizes the
elongation while not affecting the "suppleness" (it's ability to bend around
a specific radius without buckling or bulging).

==========================

It's just like 'strapping tape' that has woven fibreglass in it. Unlike
shipping tape you use for packing boxes, which can stretch or break,
strapping tape will hold a TON of load before breaking. You can _clearly
see_ the fibers in the side view of the timing belt.

The usual area of failure on a TB is when the teeth shear off because
the fibreglass threads have finally lost their strength.

'Inspecting' a Timing Belt is usually a waste of time unless the idler
has seized and the backside of the belt will show chafing, or there's
leakage problems and the belt is soaked with coolant or oil..

Or if you suspect a thief may have taken it and replaced it with a belt made
of Band-Aids with cartoon characters on them. Otherwise, I agree - a timing
belt about to fail looks like one with a few miles on it.
