Project OSIDIAS video walkthrough
ByI had a little time over the weekend, so I thought I’d make something special for everyone that has been following this project. This is a video walkthrough of OSIDIAS. It explains how some of the components fit together, and I cover some of the design basics. Although I’ve left out a few details, I think you’ll understand the project a little better. Enjoy!

Very innovative, I like this case.
However, there are a few issue’s I see with your design. I’m not sure how experienced you working with carbon fiber and Kevlar composite’s, but you seemed to have missed one vital point with your demonstration. You might be able to cut out a couple of the larger holes in the carbon composite, but with the stiffness of the composite you will have to deal with vibration and cracking issues the more you cut it. Look at it this way. with one hole you create X amount of vibration. with the second hole (depending on the complexity of the part of course) you have to deal with X+Y vibration and it continue’s adding up. The more opening’s and the greater the stress on the composite the greater the chances of causing a failure in the material.
Now Kevlar is not as prone to this obviously if you understand the nature of Kevlar itself. Straight carbon fiber is extremely sensitive to this, and is almost never used in a bond by itself if the environment is heavy with vibrations. It is almost alway’s cross woven with Kevlar in these situations.
The stuff is amazing don’t get me wrong, it’s just I’ve worked with it for 13 year’s now, and the best way to do any molded work is to mold the hole’s into the form itself, and then, use a dress piece on the outside if you want that weave look. That pretty weave stuff isn’t as strong as a properly laid mold, and to be honest I don’t think anyone would want to risk their multi-thousand dollar PC to something like a structural failure. Oh and a side note, make sure you get your grounding down really well. the 2-part epoxies used on the fiber weaves, and gel-coats themselves are very prone to developing static, so ground the fiber case directly to the PSU main ground if possible.
Please feel free to contact me if you have any question’s.
I like your concept.

LOL!
I’m NidStyles on XremeSytemes if you have any question’s. Forgot to give you a way to contact me.

Thanks for the input. I’ll take you up on your offer for further advice and contact you when I get a chance.
I’ve not worked with CF extensively, other than a few recent test runs. Most of my experience has been with fiberglass, which is not always a direct comparison. I have however, talked at some length to markkleb, who has worked with CF and CF/Kevlar blends extensively in modding. I’m sure he’s not had any strength issues from multiple cuts and their associated vibration, but I can ask him specifically. It seems his biggest issue was always getting the Kevlar to cut cleanly. Since I have quite a few cuts to make in the CF/Kevlar blend, this is also a huge concern of mine. Anyway, I’ll be in touch.
