The standard 17 oz double Bias fiberglass cloth by Vectorply is an E-BX 1700-10 (+/-45deg) with a total weight of 17.92 oz/sq.yd (608 g/sq.yd). This high quality biaxial fiberglass cloth provides more strength than standard 12 oz double bias cloth, but with some added weight.
The cloth helps to bulk up on strength without requiring multiple layers, and it impregnates easily. The weave is retained by a thin polyester stitching which holds the perpendicular 45 deg tows in place without affecting structural integrity.
Experience fantastic results while used during wet lay-up, vacuum bagging, or infusion. The 50" wide cloth is sold by the yard or roll (125 yd).

I was considering using three layers of 6 oz biaxial to wrap a new plywood core rudder for a 24' sailboat since I believed the 6 oz would be easier to work around the rounded edges of the 1 1/2" thick rudder. Will I have trouble if go with 17 oz biaxial instead?
The woven cloth will be much easier to wrap around a 1 1/2" radius than the biaxial cloth. If you wet the biaxial out first it will make the bend easier.

I am considering this cloth instead of the regular 6-7 oz. cloth for added strength on a 16' skiff am building. Would you ay this would be suitable? The boat is a Glen-L Center Console with raised bulwark. Thanks, Gary

will certainly be stronger, issue I had with it was it took some effort to get all of it saturated when laying it out but worked well then covered it with a 4oz just to get a smoother finish (I used it to make a trailer lid)
Is the $8.65 /yard for a running piece 50" wide and 36"(1 yard) long or is it for a square yard? A 3' piece of 50" fabric is actually 1.31 square yards would then cost $11.33 per square yard. Could someone please clarify? Thanks
This is sold by the linear yard at 50" wide at $8.63 per yard, so three yards would be $25.89.
The price is for 1 yard and 50" wide $8.65. The weight of the glass is 17oz for a sq yard.
I'm not sure. I bought this small piece to do some small fiberglass patching. I suggest that you ask the Jamestown staff who would have a clerar answer for you. Dave.
how easy is it to wet out this cloth with epoxy resin?
It is a little trickier than the regular cloth for sure biggest thing i found was just had to go a little slower and once it started saturating it was easy but the initial "wetting" was definetely different not harder. Flat area or gradual curve, okay- sharp curve or edge real pain. This was the first time, i had laid glass in over 20 yrs in October. It was for a lid for my trailer. My layup was 2 layers of 17 oz biaxail with about 80 % overlap (second piece much easier) then 2 layers 4oz cloth (super easy) with medium hardner epoxy
Biaxial cloth installed yesterday
I'm building a dory to row the Grand Canyon in March and we used this cloth for the hull protection

well made biax - easy to work with
I purchased the 17 oz biax to use in the repair of the transom on our Bayliner 3270. The repair included plywood and epoxy, and in order to properly reinforce the new plywood it is necessary to use 45 degree biax when tabbing to the hull. I found the Vectorply to superior to other cloth I have used in the past, and found that it layed in the corners easily, absorbed the epoxy quickly, and was generally easy to work with. There are alot of loose threads if you have to cut strips as I did, but no worse than any other matting. Note that cutting this cloth will dull scissors very quickly - you'll need quality tools if you have to piece a lot of it out.
