[@andrewstambaugh240]

Very well done. As a mechanical engineer, i knew of the trade-offs of the various materials, but i had no idea _how much_ more expensive carbon fiber would end up, nor had i seen such a through head to head comparison. It's also worth mentioning that carbon fiber is conductive (good and bad thing, eg galvanic corrosion) and so abrasive at it's free ends that fasteners need to be rethought to handle that. (Eg carbon fiber wheels are super cool, but not if you ignored that problem and the carbon fiber slowly cuts into your studs and suddenly sends your wheel off on it's own merry adventure)

@@karsnoordhuis4351 i ain't an expert but I would be very careful laying up varying FRP cloth over large areas. I doubt it's a problem for small objects and shapes but over large areas the differing cloth types could move in different ways, pressure, temperature, external forces etc, this could cause 1 type, ie kevlar to break the plain fibreglass or vice versa.

Excellent explanation! I learned a lot and the world doesn't need an overpriced driveway ornament. Keep up the good work!

[@mndlessdrwer]

One thing you can do with composites that people often overlook is just scrap an entire layer of fiberglass on your large panels and do what car companies have been doing for decades on hoods, trunks, and other large, flat panels that can't adequately support their own form: bond a skeletonized reinforcing structure to the bottom. Build this structure out of whatever you like, be it carbon fiber, fiberglass, or even aluminum. Doesn't matter terribly much, but you want to have a flanged U-section for the cross-sectional view, because this offers the best compromise between the number and size of supporting sections beneath the panel. Then you just use panel bond to stick it into place. If you've got the willingness to make quite a few more molds, you could do this for any and every large panel on your car, though it often becomes overly complicated for fenders and quarter panels to ensure that your supports don't impact panel fitment to and sub-structures in the car that the panels need to bond to. Another option is a sandwiched construction like you see for large sheets of structural carbon fiber, where the outer carbon panels are bonded to an aluminum or titanium honeycomb material to increase structural rigidity further and prevent panel flex. You see this sometimes when people decide to flex and use carbon fiber for the underbody aero control on their cars, since you can get a flat bottom for your car that adds very little weight and can also be a structural member for the car and even help keep the lower edges of body panels very firmly supported.

I agree in all areas I have used all of these in the makes of boat and car plugs, molts and parts, the carbon world is for very expensive items. However like on the keel of a powerboat i would often lay chop, weave, ten thick carbon 1 inch wide into the center line of the keel. That stops the flex in the overall boat length and removes the need to form a wooden rib in the keel tunnel to run the length, and under stress there is no delamination under high tension and speed.

[@davidgoff5883]

Entertaining and educating ! Love your videos!

[@erichraudebaugh]

I think another point you could make is that any damage to CFRP tends to be much more catastrophic than with fiberglass composites, mostly due to the added stiffness. You discussed this tangentially, and I'm sure you're very aware of it, but any repairs to carbon fiber are awful and often you have to just remake the part (and repairing means you lose the weight advantage). Glass fiber is far more forgiving, so if this body is damaged it can still be repaired, at least possibly. Carbon fiber is great if you really don't care about money.

[@BuilderCreator]

Yeah! Most expensive carbon fiber cars have specialty repairmen who travel the world fixing their brand. The local autbody shop is I'll equipped and short of knowledge in what's under the paint.

[@guillo88]

Exelent video, very clear. I would love to see in the future the explanation when you use carbon fiber, or kevlar, to explain why you choose to use it in that instance. Cheers, thx for the vid.

[@BuilderCreator]

I'll try to point out my logic as I work through the videos.

[@andrewstambaugh240]

A long driveshaft for high torque transmission is an example of an ideal case for carbon fiber. Not only is the rotational enertia savings significant, but it also has a better fail mode vs metal shafts. As some others mentioned, some places you want stiffness (eg keel on a boat, eg engine mounts, etc). But stiffness also comes with the penalty of stress concentration. It's better to have a fender that flexes rather than impacting the frame. Think of both the impact energy needing to be absorbed, but also think about the leverage.

[@evil_me]

From building body components, engine components and structural components... I find that on my projects carbon fiber is really only cost effective for engine components. Structural components end up heavier with glass but for a street vehicle I haven't seen where it would be a detriment. Interior components for the cockpit are always fine in carbon in my opinion as one layer will be enough with a good design and will retain the look. I tend to use a Kevlar glass mixed weave for bumper and inner fender body parts. Hell I use chopped mat for some large flat parts because it is extremely cheap to get in my area and is "strong" enough

Great explanation, but you haven't answered the most important question: what color will it be?

[@BuilderCreator]

Cobalt blue with tinted blue carbon fiber accents and orange trim.

[@mndlessdrwer]

That really lightweight E-glass seems like an excellent choice for body panels that don't need to offer structural support, since they would resist damage from slight impacts a lot better than carbon fiber. The challenging thing about kevlar that I've learned from people trying to turn it into bullet-proof tiles or plates with resin, is that once you've bound the fibers into a matrix with resin, it loses a LOT of the energy dissipative properties because the fibers can no longer deform plastically and are instead forced into deforming through shear forces. So while a kevlar reinforced resin panel will likely still remain in one piece after taking an impact, it isn't quite as true to the characteristics of the base material. This is a wild demonstration, though. I hadn't expected the single layer of 4oz E-glass to remain so pliable while also still holding its shape when not under load. Probably has to do with the inherent ductility of the resin used, but it's pretty impressive. I haven't finished watching yet, but I hope you go into how molding composite materials for strength is quite similar to stamping sheet metal parts, for instance, the unibody construction of cars.

[@TheBreaded]

I don't know if I missed it, but a point to make here would also be: not all of the weight is fiberglass. Even if you're saving half the weight, it's half the weight of like 20-30% of the actual car. So if a car weighed 3000lbs with fiberglass, it'd be like 2500-2700lbs. Though I'm spitballing the cars weight ratio of bodywork vs frame, suspension, wheels, drivetrain, engine ect.

[@BuilderCreator]

I haven't given a break down of the entire cars weight, but I did elude to the composites weight being about 800 lbs ( 400lbs in carbon) So, true, that most of the weight is NOT going to be in the composites, but rather the engine sub-frames and suspension. FYI-Trying to keep the finished "wet" weight under 2000lbs.

It would have been nice to see you test an 18 oz stitch e glass against three layers of 6 oz woven.

That was an astounding amount of work you prepared and analysed. Thank you. Do you think experiments in fibre glass for developing a product would give you any indication of fibre layer layup behaviour, given the basic mechanism (fibres / orientation / set resin) are the same? For experimenting I would prefer the cheapest option for mistakes and learning, and then do the final product in CF for aesthetics and its properties. Also: I have looked quite extensively and am struggling to find information on layup and fibre orientation and its impact on final product properties. Do you have any suggestions on books or papers? Thanks.

[@BuilderCreator]

Your describing the exact practice of the Arete build; work out the bugs in glass and then move on to carbon (should it ever go to production). The fiber orientation and planning is being resolved in this prototype. Most books on composites are WAY to technical. The best and easiest descriptions come from the experimental aircraft builders world; they have to describe it simply, as non technical people are building planes, but they do have to understand, as life is on the line.

There's other stuff to consider as well, like fatigue life and compatibility with other materials or whether or not the body material can act as another structural material such as the suspension arms. Stuff like "can I put a bolt through this, or does it need some kind of spacer/bushing first?" With all of that in mind, what do you think are the most viable materials to build a car out of while maintaining reasonable lightness, toughness, compressive and tensile strength, as well as long-term durability, and repairability? I know aluminum also has a finite fatigue life, but would it be suitable for the chassis of the car? I was thinking that a unibody welded aluminum structure where every panel is actually made of two thin panels glued together with a constrained layer damping glue (for sound deadening purposes) would be ideal, coupled with (based on this video) carbon-kevlar or just straight kevlar body panel skins.

Besides, my own build would revolve a LOT more around the fitment of certain things and proportions. IE specific tire sizes and wheel specs for common aftermarket wheels with specific clearances for larger if desired, the need for enough space to hold 2 luggage and 2 carry-ons WITH two 15-inch subwoofers in an appropriate enclosure, being a 2+2 with acceptable legroom and headroom for the rear passengers, and being just barely front mid-engined with a large displacement V6 (meaning a fishing line between the center of front wheels would be barely grazing the front of the engine block) while a V8 or larger would push it towards traditional front-engine placement. The combination of the latter two would be in an effort to keep the wheelbase reasonable.

[@meadmaker4525]

Here's a question for you. Why not add a single layer of carbon fiber in each of your E&S glass layups to gain the best of both worlds? You've added Kevlar here and there, so I'm assuming you could do the same with the carbon fiber. Would spending, say, an extra $1000 on enough carbon fiber to do a single layer addition to the layup (assuming a moderate ounce weight/weave to make it worthwhile) make enough of a difference to make it worthwhile?

[@FicaGTI]

some explanation on this question that you have... kzbin.info/www/bejne/oGjFgox7qcSkqrc

[@BuilderCreator]

The short answer is probably not. You could design the layup to work the way your thinking, but if misplaced, the carbon may fail way before the glass and then it is just there adding weight (as small as it might be.) Without a deep understanding of the materials it is best to just stick with one type of fiber in the layup and mix materials as Components rather than layers. (i.e. the carbon brace on the a-pillar) The Kevlar I have added is just to hold components together in a bad impact, so it all can be driven to the side of the road rather than having to run around picking up individual pieces.

[@ioiwut4874]

im no engineer .. but im curious - could something be made with plies of varying material? something like the cheap stuff sandwiching the good stuff. or even just one different ply on top? like if they can properly adhere, something like fiberglass, kevlar, and two more fiberglass plies. would that be an improvement (albeit potentially inadequate) in general? disregarding cost.

[@BuilderCreator]

You certainly can mix materials, but need a REALLY good understanding of each, as some may negate the benefits of the others. Take a look at a snow board and you will see fiberglass, foam and polyethylene all mixed in the layup. Best just to stick with one fiber and a core if you are not absolutely sure.

What if you use the outer layer carbon fiber and glass inner layers, then you don't have to paint it?

[@BuilderCreator]

The theory works if you are after the carbon fiber look. I will be using carbon fiber on some trim, but the main body will be a beautiful cobalt blue!

I always thought that the greatest advantage of kevlar was how it responds to overload compared ot say carbon?

[@anomamos9095]

If you’re building a crash structure (something to absorb impact forces) for a car you actually want to avoid carbon fibre. Depending on what you are trying to achieve you may want a mixture of glass and Kevlar or glass and foam or glass or Kevlar. If a sledgehammer could impart a force of one ton you could easily build a carbon structure that could comfortably hold one or more tonnes yet shatter to pieces if struck by said hammer. Where another structure of glass fibre that may crumple under a one ton weight would resist the sledgehammer blow and bounce back to take another, as they say it’s horses for courses.

Your exactly right, I could have made a shorter video by just sledge hammering a few panels couldn't I?

@@BuilderCreator too much effort to clean up the mess but a lot more spectacular 👏👏👏👏👏
