gullikson Posted September 27, 2008 Share Posted September 27, 2008 Does anyone know if the Standard E-Glass and Fiberglass tapes available from Aircraft Spruce have the major fiber bundles running at 45 degrees to the selvage edge (can't tell from the picture)? According to the catalog, these are 8.7 oz/sq. yd vs 8.8 for the Rutan BID a seemingly insignificant difference. If these rolls of tapes are 45 degrees to the selvage edge, has anyone used them?

Steve Innova Posted September 27, 2008 Share Posted September 27, 2008 No, they run 0 and 90 degrees, not 45 degrees. Don't use them. Quote Link to comment Share on other sites More sharing options...
gullikson Posted September 27, 2008 Author Share Posted September 27, 2008 Thanks Steve. I was afraid of that since I have yet to see a selvage edge on any cloth that doesn't run 0 and 90. Can't imagine what those tapes would be useful for being that they are in an Aircraft Spruce catalog. Was hoping there was a way of not having to cut my own tapes (for the 4th time)!

Steve Innova Posted September 27, 2008 Share Posted September 27, 2008 Easiest method that I've found (stolen from Cozy Girrrls, I think) is this: Lay out 2 plies on a sheet of aluminum foil. Wet out the glass, ensuring the epoxy goes through both layers. Cut 2" wide strips (I am using the roteray cutter, easy to cut straight lines) Pick up the 2" wide strip the foil backing, transfer it to the part, and press it in place, with the foil on the top side. Remove the foil, add peel ply, press out any air-bubbles, and you're good to go. Very easy, the glass plies don't get all stretched out or frayed edges.

TMann Posted September 28, 2008 Share Posted September 28, 2008 I've done the same with poly. Wet out a couple plies, cover withthe second layer of poly and use the pizza cutter to cut them into 2 inch wide tapes. If you plan ahead, you can roll them up and store thrm in the freezer until you need them (about a week) then apply them and warm them up with a heat gun.

gullikson Posted September 28, 2008 Author Share Posted September 28, 2008 Guys, thanks for the tips. This is my 3rd canard airplane, and 4th homebuilt. Just thought they may have finally figured out how to make the various width tapes with the correct 45 degree fiber orientation to the selvage edge so I wouldn't have to cut the dang things. cheers, Quote Link to comment Share on other sites More sharing options...
brainfart Posted September 28, 2008 Share Posted September 28, 2008 Such tapes exist, I've seen them. Quote Link to comment Share on other sites More sharing options...

gullikson Posted December 24, 2008 Author Share Posted December 24, 2008 The bias ply material shown in glass only goes up to 1.5" wide, otherwise it looks like it would be perfect for taping seams. They do have Kevlar 2" wide but I don't know if this would be an exceptable substitute. Quote Link to comment Share on other sites More sharing options...
