This is intersting..UV light on carbon fiber
i fly fish and tie my own flys..one of the tools we use , is a uv cure epoxy... i was playing around with the UV light on my bake.. and i noticed on some carbon parts like my campagnolo record crankset..nothing happends.. but on some carbon parts it fluoresces.. any thoughts here?

Some component of the epoxy or clearcoat is UV reactive. Different companies use different products so some fluoresce, some don;t

I don't think the UV light is revealing anything about the epoxy in the carbon itself. Bike stuff uses epoxies that cure mostly under heat.

Carbon fiber bikes are just a part of the throw away society we have now. They are like most things these days, nothing is built to last.

Presumably, in order to make this claim, you have some data on the percentage of CF bikes that survive X years or X miles and compare unfavorably to bikes made of steel, aluminum, or titanium. If you don't have that data, then you are expressing bias, not facts. And before you start, I have only ever owned steel and Ti frames. My current and previous Ti frames have about 240K accumulated miles between them.

All equipment has finite lifespan. The problem with carbon fiber, unlike steel, aluminum, or presumably titanium, is that it is almost impossible to recycle once its service life is done.

Ridiculous, as usual. I fully expect all of my CF bikes to outlast me. Nothing indicates they won't do exactly that.

Accurate. However, a damaged CF frame is often repairable. Sometimes steel is, too. I'm not sure about Ti. A damaged aluminum frame is on its way to becoming a 12-pack.

Obviously, some of your carbon parts are crime scenes.

I went to an event at a country club built on a hill in my home town that didn't exist when I was growing up.

That's not "recycling," but more like sweeping the problem under the rug. And doesn't prevent plastic resin microparticles from contaminating the environment.

People need to watch the video in post #5. The truth here is that the carbon fiber probably is not affected by UV light. It is the epoxy which is a plastic that is affected. Add to the UV the problem is that all plastics get brittle with age.
