The carbon fiber is just reinforcing material for the ABS composition
plastic substrate, which is why I recommended (and use)
ABS adhesives. (The plumbing adhesives I discuss come in 3 versions: PVC
only, ABS only, and PVC+ABS.
I recommend against the first. There are specialty ABS adhesives that are
likely better than the plumbing
variety, but the latter is universally available.) I've never tried the
styrene adhesive Jack suggested on a laptop case.
The problem with epoxy is not strength - it is wonderfully strong - but
adhesion. Epoxy is one of the least sticky
glues there is, and has trouble getting a proper bite on most plastics. (By
contrast, CYA adhesives like superglue are
very sticky but lack strength, and will fail under torque. Worse, it is
often the first glue people try on plastic, and
when it fails it leaves a hard-to-remove film which makes it even harder for
other glues to bite.) However, it is miles better
than the ABS adhesive when there are gaps, since the latter is designed for
flush surface-to-surface contact.
