Recommendations for gluing nylon cf?

So i’m working on a custom project and there is a load bearing part that needs to be glued but i cant seem to find anything that will hold it together well enough. I’ve tried JB weld Epoxy as well as rubber cement and neither of them worked. Would prefer to glue as it’s in spot where a screw wouldn’t really fit. But if need be i could make some adjustments. If anyone knows of anything that will work and that can handle like 15-20 lbs of load i would really appreciate it.
