Can the timing chain be stronger and more durable since it does not have to shift ?

I have a timing chain that I assume is stretched and came off causing injury to my stoker and associated negative attitudes.

I dont see a way to attach an idler gear to maintain tension so my only option is to get new chain that I hope will be shorter and less likely to come off.

Since the timing chain does not shift I was wondering if a much heavier duty chain is available that would resist stretching longer.

I can take a micrometer and measure the width of the teeth on the timing sprockets if that would help. As it is, my tandem has an 8 speed
Cassette and is probably 16 or 17 years old. I guess I should replace the shifting chains as well. I googled bicycle chains that stretched
the least and the consensus is that the stainless steel chains last much longer but I cannot find them for older 8 speed systems. Believe me money
is no object compared to a big bloody gash in my stokers calf.
