Strength, toughness and design standards are all totally different things. Of course some manufacturers can do it right and when done right it can be VERY strong. This is why it’s used in planes and F1 cars amongst other things. The thing is those are all tightly inspected, designed by experts who have countless years experience in doing it and designed in a way that prevents it being subjected to its kryptonite failure methods.
For example, my carbon cranks were lovely, tough and super-stiff. Bounced off rocks dozens of times, took the full force of me landing 5 ft drops. But after some use, left wet a few times and then abused again they failed catastrophically, de-bonding from the alloy inserts and subsequently snapping in half miles from home.
Horses for courses.
