Guys,
I've installed prepreg webs to build up a dry D conduit on the leading edge
of my IV-Ps wing.
I did this by removing core and then floxing the pieces in place. While
installing the webs, I also created a flox fillet that should lock the
prepreg panels in place.
Now the $500,000 question: Should I install a 1 or 2 BID layup from the
lower skin, up the aft face of the web and onto the upper wing skin / joggle
(only about 1/4" available to wrap glass on to)?
I can come up with arguments for going both ways.
NOT TO INSTALL:
- No additional weight
- The web isn't _necessarily_ structural (since it didn't have to be there
in the first place)
- Save a bit of work
TO INSTALL:
- All the other webs forming the fuel tanks are secured in with 2 BID
- Since I am holding fuel with these thinks, the 2 BID would be one more
insurance policy against a piece coming loose and causing a severe "fuel
event"
- I'm concerned that, because I have installed them that the webs WILL take
on structural loading. If so, using 1/2 BID on their aft faces might be
important.
