You could always use fiberglass as well.. The close-up shots that actually show the weave in the cloth can be had with regular fiberglass cloth and resin. You can then simply airbrush the dark tint over top or use something like Night Shades

Re: carbon fiber tdk suit


Does the kevlar carbon fiber fabric have the same ballistics properties as the kevlar in the vests?

Re: carbon fiber tdk suit


hey bro, as far as my experiance goes, it does NOT have ballistic properties. It will stop a knife or crowbar, but not a bullet.

Re: carbon fiber tdk suit


Kevlar fabric most certainly does not have the same properties as kevlar found in ballistic vests or helmets. It is made out of the same thread, but it's usually a different weave and is layed out quite differently. If you really want to know the specifics, there's a nice explanation on howstuffworks.com.

I'd be hesitant to claim that kevlar will stop a knife either. Kevlar is used in tactical gloves which are "slash resistant" but that is far different from "stab resistant." The mechanics of a slash are much different than a stab. Rule of thumb, if flying glass might be an issue, it'll probably hold up. If you're trying to stop an ice pick from going through your lung, you'd better look somewhere else.

When it comes to making plates, you can use the kevlar/epoxy setup. It certainly won't be as strong as vacuum forming and heating (for CF), but you might be surprised with the results. I'd recommend, as BRCEWANE also has, to do a test with fiberglass. It's heavier than kevlar for the amount of strength it gives you, but it's very similar to both kevlar and carbon fiber weaves if you're going the epoxy route. A sheet of fiberglass about 8ft^3 and a tube of epoxy can be had at any hardware store for about $13. <-look in the auto-repair section.

I've made 3 cowl face mask thingies out of fiberglass using the Rubies mask as a mold, and I am quite happy with all of them. I tested one of them and it was quite good at stopping strong cutting motions from an xacto knife... failed when trying to stab through it though. Using kevlar or CF, you'd have lighter weight and more strength. Just get the technique down before you end up messing up the more expensive matierials. If you're really cheap you can use elmer's glue and paper towels.

Re: carbon fiber tdk suit


Caveman, when I said it would stop a knife, I should have elaborated a bit more. What i should have explained is that the kevlar once impregnated with the epoxy would make hard plates the COULD stop a knife depending on the thickness of the plates.
My first attempt, I only used two layers of kevlar felt and, using a hunting knife, I took a stab at it and the knife point went throught the other side about 1/2 inch. when I made another attempt I used 4 layers and the knife did not penetrate. So, it definitely does depend on a few factors and there is no gaurantee, but it is feasable.

Re: carbon fiber tdk suit


Manbat01: While homemade armor can never involve assurances or guarantees at all, perhaps the weakness of your two e-K layers could've been due to the kind of epoxy used or improper proportions of resin and hardener or insufficient impregnation or improper curing. And Kevlar® also loses its strength when exposed to sun or strong light for any length of time, so Plasti Dipping is a good idea for a number of reasons.

Kevlar biaxial weave cloth can also be sandwiched between two felt layers. Here's an Archives thread that includes discussion of some materials:

Kevlar® Armor Your Cowl

Again - no assurances, just a few tips!

Re: carbon fiber tdk suit


So Zane sorry if this is asked and answered else-where but I'm just curious why you seem to prefer the closed-face cowl look?

Re: carbon fiber tdk suit


It's a good question, HC!

I don't like phony cosmetics of any kind because I build suits, not costumes. This means no eye shadow, as well as protecting and concealing the face with cowl eye-mesh and a Nomex® double-holed balaclava. The Simpson Balaclava shields from fire and acid while also providing air space inside the cowl for a little added ventilation and sweat abatement. Every part of the suit has a function -- even a steel glove-fins idea that I've only suggested for gripping, and that WB later used for Begins.

Re: carbon fiber tdk suit


Hey Zane, I used the 127 and 606 that you mentioned in your tutorial and I kept it in a cool dark basement with no sunlight. So, did I not do something right in the process? Basically, I cut the shape, immersed it into the resin, then formed it in the mold. I followed the mixing directions.
Did i miss a step or is there something I should be aware of the next time I try this? I ask because I will be trying to redo this soon. I would appreciate anything and everything you could tell me.
