Fiberglass, Kevlar and Carbon Demonstration

[wavepsychic]

What the hell did I just watch?

[Louis1012]

Great video. If one were to want to make ballistic plates out of kevlar, i've heard that K29 745 would work? Would epoxy resin work just fine? What hardener should I use?

[MrSteamdog]

I can`t see you movie because of your fu##ing ad.

[SuperLouis555]

kevlar doesn't melt at all. It chares at well over 500 degrees. Put it in fire and you can see.

[kittykawaiix3tr]

I have been trying to learn how to make bulet-proof armor. A friend told me that I can use melted Kevlar? 

[nightSpiritUK]

@kittykawaiix3tr LOL!

[TheDeliBekir]

what is the best material for the music instrument?  I am thinking very thick guitar to build one? cheers

[stivaro]

I tested kevlar myself. Check it out. /watch?v=r7PAlkIW85s Proven stuff man.

[paulwisdom2008]

At about 3:20 you say you'd rather use more resin, but if im right i recall that you need less resin to make stronger parts? I mean make sure its soaked through but too much just leads to a weaker part i was told?

[JamestownTV]

I believe he was only trying to emphasize the difficulty of wetting out Kevlar. It's true that less is more, however you must make sure the cloth is saturated.

[paulwisdom2008]

@JamestownTV  Ah okay, thanks for clearing that up for me :) I've never attempted anythign with Kevlar so i can't say i'd have understood the difficulty!

[o0murphyslaw0o]

always make a pre gelate

if u build optic ;)

[Appledude500]

is it a good idea to make "carbon fiber - kevlar - fiber glass" sandwich if i want to make fender for my car?

[JamestownTV]

I would skip the Kevlar part. Make is out of several layers of 6 ounce fiberglass cloth and as a final touch for cosmetics use a layer of carbon twill weave cloth.

[o0murphyslaw0o]

take 400 g / m² fiblreglass and 3 layers

[JamestownTV]

You're welcome. We're glad to help out.

[asphaltvictory]

thanks for helping out chariho high school!!!!

[bushbosh]

what is the use for these please, i am new to this

[Theshadowrazor]

Where do you buy your materials? Carbon Fiber, Kevlar and so forth? Are they very expensive for doing just home projects?

[JamestownTV]

We sell carbon, fiberglass and kevlar cloths.

[crzykabazie1511]

@JamestownTV

I am doing a project on  kevlar

[JamestownTV]

Well, we sell kevlar. You can find more about it on the Jamestown Distributors' website

[adeelrehman]

Good video to show how the resin is applied in a composite but in my opinion there is a lot more resin used than required increasing the weight of the material, taking longer to cure IF it is not squeezed out by compression (bleed). But these seem to be just the test samples, not the actual part. So its Ok in this form.

[ecfibreglassuk]

Good Video

[wankstataz]

yeah i'd say its a little resin rich aswell.

and i'd laminate the material (aramid, f/g, carbon) in plastic, and squeeze out most of the resin.

yeah true errbody got their own way of doing it. you gotta have teh goodstuff resin like hysol 828 on carbon and gell-ing it for a godo 2-3hrs. and heating should be graduall.

[NEUMOBIKE]

excuse me, does exist compressed air tanks made with, fiber glass, carbon or kevlar??

[natyong]

Yes, there are, Well kinda. They normally have a metal bladder (aluminum) that holds the air and have a outer layer for strength which can determine the thickness of the inner bladder depending on the the outer layers construstion.

Search google for "carbon fiber air cylinders

' for a lot more info.

[JamestownTV]

Well, everyone seems to do things their own way. It always seems that pros don't do things according to the manufacturer's directions. Their years of experience often tell them something different. This demo was of a sales rep who has many years in the business.

[ILOVEORANGE12]

u use way too much resin
