Product Details
Plain weave 5 oz. Kevlar cloth is a high tensile strength and high modulus composite fabric, great for canoes, kayaks and racing shells where maximum strength and minimal weight are critical. Impact, tear and penetration resistance is far superior to fiberglass. 0.01 in thick 58 inches wide. Sold by the yard.
Info & Guides
Kevlar was developed in the early 1960's by Dupont. Assuming the same weight, Kevlar is literally five times stronger than steel. Kevlar fibers also have 43 percent less density than fiberglass. Originally developed to replace steel tire belts, it is an aramid with high strength and notable heat resistance. Kevlar's biggest weakness is its lack of compressive strength.Thermal properties
Highly flame resistant
Can handle temperatures to 320 degrees F for extended periods with ease
Significantly lighter than even E-glass
Will not melt (at 800 degress F it begins to decompose)
Why is Kevlar so useful for composites? A few reasons:

Q: null I'm looking for a product to wrap a Sitka spruce iceboat runner plank to prevent spikes on my shoes (used for grip on the ice) from penetrating and damaging the wooden plank. Will a wrap of kevlar/epoxy do the job?
4 years ago4 Answers
A: Kevlar is cloth and, of course, without resin/epoxy, spikes can penetrate between the weave. So, your resin is either soft enough for spikes to grip (e.g., Gflex) or hard enough that they don't (some epoxies). If soft, not enough protection for the plank. The spikes will penetrate - even through the cloth. If very hard and footing slips, why step on it at all? Then, don't cover and enjoy your Sitka spruce. You seek secure footing and protection for the wood: soft enough to grab the surface and thick enough that your spikes do not pass through. Would rubber (thicker than your spikes) do, or does that ruin the aerodynamics?

Q: null I'm looking at sheathing the outside hull of a boat I'm building with Kevlar. Which would be stronger, the twill or the plain weave?
6 years ago1 Answer
A: The twill is stronger than the plain weave. Kevlar is a high tensile strength and high modulus composite fabric that is great for canoes, kayaks, and racing shells where maximum strength and minimal weight are critical. Impact tear and penetration resistance is far superior to fiberglass. 9 oz, 58"" wide. Twill weave kevlar cloth drapes around corners easier than regular kevlar cloth, and twill weave also wets out better than plain weave kevlar. Twill weave is a basic pattern discernible by a diagonal rib, or twill line. Each end floats over at least two or more consecutive picks enabling a greater number of yarns per unit area than a plain weave, while losing little fabric stability. This type of fabric looks different on one side than on the other. The fabric is .024 in thick.

A: It's Kevlar. I wouldn't worry about shelf life; it'll probably last longer than either you or I will.

Q: null What is the best epoxy system to use with this Kevlar? Total boat? West?
10 years ago1 Answer
A: I suspect they're equivalent. I used WEST that I had on hand, and was happy with the results. One note: it tends to take a set if left folded as shipped, difficult to pull flat and keep it from ridging up at the folds when laminating. Remove it from the folded shipping packaging soon after receipt and roll over a cardboard tube if you expect much delay before using it.

Q: null Our boat's bimimi top is getting frayed by the wakesurf rope. Is this fabric something that would work as a patch sewn on top of the present Sumbrella fabric to prevent fraying in the future? Does this come in other colors (black)?
11 years ago5 Answers
A: No and no. This is plain kevlar, so there is no die or coloring. As plain kevlar it is also susceptible to fraying when subjected repeated abrasion. That being said, if you were to apply some kind of coating as well, say resin or rubber, than this could work well as a patch.

Q: null Will this Kevlar wet out clear like fiberglass or is it yellow?
11 years ago3 Answers
A: I was concerned the vendor had to send out this question till I saw the picture....It is yellow and wets out yellow. It is more challenging to use than glass as it tends to float in the resin and fuzz up in sanding, a grinder can be helpful. Special scissors are required to cut it, try to be accurate as it won't feather like glass after you are done. I suggest using it inside a hull skin as it has high strength in tension but low compression strength. It can also wick up water if used outside the hull and the resin barrier is breached.

Q: null Will this Kevlar be able to withstand the sharp edge of a snowboard without adding anything such as resin or apoxy to it?
12 years ago2 Answers
A: No. This kevlar is impossible to break or tear, but it can be cut relatively easily with anything sharp. You should definitely use apoxy or resin if it is going to be in contact with the sharp edge of a snow board. Even if the snowboard didn't cut it right away, any repeated abrasion would quickly wear through the kevlar. Hope this helps.
