Gary,
 
Cutting carbon mat is best done on a solid surface. In my experience, the
common practice is lay it on steel or glass, use a steel straight edge and
an X-acto knife with a sharp blade. For small applications like those
diamond shaped dihedral joint reinforcements this should be pretty easy. If
it's a pre-cured matt, sharp scissors are used too. Just keep in mind that
if you are using your wife's fine fabric shears they will get un-fine
quickly...carbon is very hard and brittle. X-acto blades are cheap compared to
them. You don't really cut carbon, you fracture it.
 
Adhering can be done with just about any adhesive and surface prep is key.
 Scuff the faying surface (the glued side) with fine grit and then lightly
wipe the faying surface with alcohol to clean it. Using any thicker
adhesive like duco or epoxy is OK but a thin coat is better so "wipe" the
adhesive off with a "squeegie" like a playing card to remove excess. The thick
CYA's work well too, but can be tricky over a larger surface. Also, using
those latex gloves helps, especially when adhering large surfaces.
 
The next issue is keeping pressure on the surface while the adhesive cures
or sets up. ( A little input on some guys who do this a lot here?)
 
The adhesive used needs to have decent shear strength relative to the
application. At dihedral joints on a Tip Launch...epoxy or CYA should be
sufficient. For most other applications, Duco or Ambroid would be OK, but Duco
stays flexible for a longer period of time...Ambroid can get brittle. For
those "X" cross bracings on HLG's and CLG's just about anything can be used
that is compatible with the materials used...balsa, foam or whatever. The
working time of the adhesive is a consideration when adhering large areas.
 For small application this probably won't be noticed.
 
Bill Gowan can weigh in on this too as he uses all of the reinforcing
mentioned on his gliders.

I would be interested in hearing from anyone that has used this type of
product concerning how it is cut, can it be adhered with thinned Duco type
glue (or just CA), what applications is it good for & what applications is it
not good for & why?
Thanks,
Gary
