There was an announcement made about it going overseas.

The announcement was made AFTER people like me got their clothes in the mail and realized they came from China and started asking questions on their forum. After a bunch of posts got deleted by moderators (which they later claimed they didn't know about??) and they couldn't hide it anymore they announced their move to China. I don't think there is a more sneaky/sleezy/shitty way to go about it possible

I saw it thrown off the cliff and run over by a truck thought this argument was over

"cliff" ;)

Carbon fiber is actually not a composite, when you add the resin or any other type of matrix or material it then becomes a carbon composite.

Carbon Composite is the most correct name for the material, however Carbon Fiber has become synonymous. CF is technically only the thread that is woven into sheets to which a resin is applied to make a Carbon Composite, which is a type of composite.

Since I don't have, nor have I seen the Kifaru stays I couldn't tell you if they do or don't have wood integrated into them, just going off they site which says CF. It wouldn't surprise me if they do however as CF composites alone are great in shear and tensile strength they lack the rigidity to be good in compression. Foam is usually added between the sheets of fiber to add rigidity, but I suppose wood would work too. Blue foam is usually used because it is light and absorbs the resin to adhere to the CF.

Aron talks about the stays on the Gritty Bowmen podcast episode 14. He says they're carbon layered with hardwood to keep the carbon from snapping. The carbon must serve some purpose or I don't think they would use it.

Yes but when you go to select the stays when purchasing they are listed as composite. The same with the bikini frame. Carbon fiber is normally used in composite form.
I am not sure I see your point. If you look at what I quoted someone posted Kifaru didn't use carbon fiber. I posted a screen shot of their page that clearly show they say the stays are carbon fiber.

Carbon fiber not used in composite form is generally fabric the layering of the fabric and the epoxy resin is what makes it a composite. Composites can be made of different materials like wood which is what the stays used to be listed as...a laminated wood composite.

Carbon is very stiff and strong but it's inflexibility is its weakness also. The the wood provides flexability and impact absorption. Carbon fiber is vulnerable to bruising and cracking when used alone in the resin

Depending on the weave type, direction, and layout carbon can have compressive strength

Just saying how they are listed in the selection area. I have a bikini frame and do know they are Carbon fiber wood composite.I'm a big fan of the composite stays and frame.

Now you can be 100% on Stone Glacier. I also somewhat remember Kurt on this forum talking about how he had helped or been consulting for Kuiu on their first iteration of packs

That doesn't say carbon fiber (carbon composite) and Kifaru uses a carbon composite as well, doubt it is 100% CF like the Kuiu. I'll have to ask Kurt about the Kuiu consulting, first I've heard about this.

Agreed, also depends on thickness. CF composites are often designed to be less rigid so that it bends rather than breaks and therefore compressive strength isn't as necessary. As an example of this, watch the video of Jason running over the Kuiu frame with a truck; it certainly bends a lot. This usually isn't desired in a pack as the last thing you want is the frame bowing into your back under load. This is something that can be managed by design. Kuiu seems to account for it by the center compression straps that probably cause it to bow out if anything.

Think it was a misunderstanding, Kuiu uses a 100% cf frame (I can post broken picture if you would like to show it is 100%). I said Kifaru uses a composite which includes wood, never said they didn't have any carbon just that they don't use 100% CF.

I have heard about the Kuiu consulting and from what I gleaned it went in one ear and out the other so Kurt went on to make the pack that Kuiu could have.

You didn't say 100% carbon stays you just said carbon fiber stays. That's where the misunderstanding was. I think Kifaru changing one spot on their website to just say carbon fiber also added to the confusion. I have no dog in the fight I was just posting the pics to show what the companies said on their respective website.

However if anyone has been scared off by the thought of a carbon fiber frame or what might have carbon or not, I would direct them to my classified ad selling a barneys freighter frame and hunter bag.

Speculation at best. Although they really should involve you

Here is the Kifaru Carbon Composite stay for those that haven't seen it.

Haha, nicely done, are you in sales :)

Nope construction, if I am having to "Sell" the job after I am done something went wrong.

I might add that the hunter bag has dyneema thread which is used in Kevlar which has properties that make it stronger than carbon fiber when measured by weight (depending on what link you click in Google search results.)

Kuiu has and does offer some fine gear. I only have used the clothing since the onset and have beat the heck out of it. All of it is still in use with the exception of a trashed set of gaiters and I bought another set because the performed very well. Having grown up in a time of wool and borrowed gear I am for one extremely pleased they are around and offer innovative gear for the hunting community. We live in America and have choices to buy what we want. Mine is to buy kuiu when I feel it is something I like knowing it will perform well until proven otherwise to me.

Ross I'm with you on this as far as clothing and gaiters but not so much on their gear.

Ah innovative, a bikini covered in Vias or Verde. Well maybe the Teton line will have stable inventory.

Lol

Come again? You live in the boat building capital of America... Re-research it.

Wood is only used for one reason. It's cheaper compared to the same amount of stiffness of CF. there is no point in using it in conjunction with Carbon fiber unless you are trying to save money on resin and amount of CF. boat hulls are a perfect example.

Three ways to give resin strength:Kevlar/glass/mat/CF, sandwhich structure(wood, foam. Etc) and/or a combination of the two.
CF is used mainly to eliminate extra mate,resin, and sandwhich structure. Thus a more ultra light product with a similar strength ratio.

I'm not a fan of 100% carbon fiber frames or bow risers in any shape or form. They have their place but as a user you have to be highly aware of the durability impact trade offs

When I dropped $1k in gear and was told it was made in North America, then when it shows up on my door step all the tags say made in China, it's hard not to hate. Especially since that was one of my main deciding factors between Kuiu and other companies at the time

Lol.....nice.

Go buy a corvair, I hear they were made in the good ol usa.
