fiberglass mesh in foam wings

[Wayne Galligan]

MessageC.F. tow is much better for length wise spans like spars.   The mesh would be good in between the spars at the aileron.

  The most expensive solution in this case I believe is the best. CF mesh from Aerospace Composites.


  Thanks, Rich

    Sounds good to me. There are a lot of ways that work well.
    BTW, some of the drywall mesh is made with very short fibers: if you can tear it easily, don't use it.
    Pattern flyers will prefer the most expensive solution. I think that is a paraphrase of something Dick Hanson said...

      John, we put 0.5 oz carbon mat between the foam and sheeting, same amount of slow epoxy ( really thin rolled on to the mat ), with a little brushed around the edges of the foam, and bag them. Gives an incredibly strong wing,almost monocaque, with little added weight. Also add a small piece at fuse end TE to prevent the "pick up bends" .
