Why are'nt there any carbon fibre fuselages ?

[Wayne Galligan]

Hitesh,

  The guys at AeroSlave make all c.f. composite fuse.  Check out their
website at  www.aeroslave.com   go to the link about materials that they use
under tech stuff/composites/carbon fiber.   They are definitely without a
doubt stiffer then any fiberglass fuse I have had any experience with.  I
have no formers any where except for the landing gear box and firewall its
that stiff.  The other key factor in their composite lay-up is the use of
laminate called coremat.  It adds a high amount of structural rigidity with
very little weight gain.  Unlike other composites that use foam like the
lay-ups, coremat will accept the use of c/a.  The fuse wont dent under
normal handling and is VERY durable.

We have had discussion about running antenna in or out because of possible
RF problems so we decided it best to run the antenna outside of the fuse.
I had a problem with one that I was running metal pull/pull lines on
elevator and rudder and even with the antenna on the outside running to the
back of the fuse I had some issues with range.  I had to run the antenna to
the wing tip.  Changed over to Kevlar pull and a c.f. pushrod and the issue
went away but still ran antenna outside of fuse.   I would and Gray would
recommend running antenna on the outside of the fuse when using an all
composite c.f fuse.

Smooth FLying...
