That’s a neat and tidy shaping bay you got there Bud. Mine’s a complete disaster zone in comparison.

Mooneemick, Randy French is flat out wrong what he is calling “Warp Glass” is actually “X-Glass”, what a barney, but a great self-promoter in the guise of doing it for the shapers of the world, but that is another story. No need at this time to tell you how he learned about “X-Glass”. At least the self-proclaimed illuminatti, such Randy French should have the basics down, but he is clearly absolutely ignorant of what he is talking about there. The glass he shows is is “X-Glass”, and it can be purchased from “Graphite Masters”. Nonetheless, the fabric shows promise for many suitable surfboard applications. RF clearly does not know what he is talking about on this subject. What a barney, HEXCELL should sue him for product misrepresentation, and pay me for pointing it out.
Hey ghettorat
Thanks for the explanation on the X glass , my bad for a dud link.
Personally ignorant as to warp , X , biaxial , triaxial etc , not really on my horizon for what I make.
Most of us only use E or S so we rely on the self proclaimed " leaders and developers of this new technology " to be up to speed with creditable information.
Looks like you’ve pulled Randy’s pants down on this one.
Cheers

Hey mooneemick, I can’t figure out how the guy can be so wrong, and yet self-assured. I hope I never get like that. And great job finding that vid. He’s a tech-parasite as far as I am concerned even his original technology is from “Sailboards Hawaii”. Nonetheless, a great self-promoter all the way to the bank- the World Bank… A little bit harsh in my criticism, but probably long overdue.
please bag on Randy F. all you want .
just to clarify:
Eglass is a type of fiber, Sglass or carbon or kevlar or … are other type
Plein wave, satin, twill are how fiber are woven, others are stitch like multiaixial (like biax, xglass is a biax stitch Eglass).
UD, Warp, Biax, triax… are the way fibers are oriented.
Multiaxial glass like surftech now use is in fact use for many times for boatrd building, nothing new .
Sorry for my frenglish
Do I have this right…???
-
You can’t have a warp x-glass because there is no true “warp”?
-
X-glass is biax. It’s E-glass woven at 45s instead of 90s?
Arghhh, E-glass is short for electric grade because it was first used in electronics as an insulator, and then found usage as a reinforcement. S-glass is short for structural glass because it is stronger (25-30%). Warp is the direction it comes off the roll, and since there are more fibers going in this direction, Hank Johns decided to name it “Warp Glass” which is owned by HEXCEL; X-glass is a biax that stiches together two layers of fibers at 45% degrees to the warp direction, so he named it X-glass. Randy French is a great self-promoter, and I respect him for that.
Sorry for my frankness…
Weaving terminology.
Warp: lengthwise in the loom.
Weft: widthwise in the loom.
In that case:
X-glass is really +/- 45 biaxial cloth. The +/- 45 or 0-90 designations are the angles of the fibers relative to the X and Y axes (width and length) of the cloth as it comes off the roll.
As Ghetto says, one layer of fibers is stitched on top of another layer of fibers. There is no over/under “weave” to the fibers in biaxial cloth (or triaxial).
Frank answers are the clearest ,thanks again
Cheers

Ghettorat - you, with the help of others, spell out the facts better than most glass company web-sites. Having looked at a bunch of sites looking for the best deal on a roll of cloth, I am so stoked to have the knowledge I’ve gained here - more knowledge here than on many of the business sites…
