Product Details

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).

well made biax - easy to work with
By pasty63 from Lake Stevens, WA

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.

Excellent biax, good dog
Bottom Line Yes, I would recommend to a friend
