Alex: You can go to aircraftspruce.com and order what you need and/or get additional info from them.
The glass sold by them is identified as "used on KR Aircraft." As others said, it is 5.85 oz/sq.yd. and is called "Lightweight Boat or Tooling Cloth. Plain Weave. Thread Count 18 x 18. Breaking Strength 250 x 250 pounds/ inch. Finished Weight 5.64 oz./ sq.yd. Thickness .009". The AS&S catalog also says all the fiberglass fabrics are volan treated for maximum strength and resistance to moisture and abrasion. As Mark indicated, one layer is used everywhere except on the leading edge of the wings where 2 layers go from the main spar over the leading edge. When this is done on the top and bottom of the wing one ends up with 4 layers on the actual leading edge. You also end up with double thickness on the leading edge of the H.S and V.S. due to the wrapping of the glass from one side to the other. Hope this helps. By and large my KR2S is stock with the exception of using the new wing templates from TET. --- "Alexander Birca (RMD)" <alexander.bi...@rmd.ericsson.se> wrote: > > Hi All, > the question is, what is the thickness and > tensile strength of fiberglass which is used > for lay-up process. > May I use one type (thickness or density?) of > fiberglass or it should be different one in > different area? > Where I can read more detailed info about used > fiberglass in KR construction. > > > Thanks, > Alex Birca > > _______________________________________________ > see KRnet list details at http://www.krnet.org/instructions.html ===== Tim Brown Lake Arrowhead, Ca. e-mail me at timwbr...@yahoo.com See my KR2S project at: http://www.geocities.com/timwbrown __________________________________ Do you Yahoo!?
