One layer of this stuff would be thinner, stronger/stiffer and lighter than StabilKore
It also will add nothing till it is bound in place with resin.

That's some interesting stuff.  Have you used it?  The 45* orientation should provide superior stability.

I have used it, but not in a bow. Only for alpine skis, which are subject to way more torsional stress than any bow.

How was it for penetration by the resin?  How did you cut it?

Awesome sleuth work there Flem.

It wets out nicely. I was using it in a "by hand"  lay-up. I use a rotary cutter, no distortion of the fabric that way. You can cut it with a fresh razor blade or knife edge tailors shears also.
If you were incorporating this into a bow lay-up using EA-40, it would be worth doing a separate wet-out of the fabric first on a strip of parchment and sliding it into the lay-up rather that trying to wet it out on a slippery lam! Might want to heat the EA-40 up to about 90* and use a roller instead of a squeegee/scraper.

Thank you Flem. Sounds interesting, but perhaps a bit difficult to lay up in a bowlimb?

If you were to wet-out the fabric by itself, it might add around 5 minutes to the layup.

Disagree with Flem...4.85 min 

Bue I lay out a sheet of material 72 " long (Cause thats the length of my form) by whatever width I want to prep then use flat aluminum straight edges 1/2" apart and spray with a 3m adhesive. I leapfrog this over ending up with 2" strips of material after I cut down the middle of the adhesive with scissors.

The glue edge on both sides of the strip hold the material intact from fraying. Ill add this to my layup with a roller and like flem said make sure your bowsnot is warm to promote better wetout.

You do waste some material this way so maybe Ill try Flems method using a rotary cutter.

Hope that was clear as mud Lol

Spray adhesive on the edges is an excellent idea Charles
Love learning something new! Especially when it simplifies work
