Hi,
Carbon fiber is added to a glider to give the
glider additional stiffness. The additional stiffness
is needed during the launch phase of the flight. If
the fuse is too flexible the glider will bunt down
when launched. If the wing is too flexible it will
flutter, once flutter starts the plane will either
destruct itself or have so much drag it will not get
any height.
People have glued on carbon fiber with all the
glues you mentioned. I like to use thin CA. I put
the carbon fiber down where I want it then run thin CA
along the edges of the carbon fiber sheet. I quickly
wipe the excess CA off with a paper towel. I do not
like carbon tow, I just use carbon fiber sheet. I
have seen others sucessfully use carbon tow.
My typical Cat 1 or 2 SCLG fuse is 1/16" wide.
For UCLG I use 1/8" wide fuses.
I hope this helps,
Kurt
