Is carbon fiber worth it? Arete Supercar project.
With materials like E-Glass, S-Glass and Kevlar to contend with, is carbon fiber truly the king of composites? Carbon fiber has the greatest stiffness to weight characteristics of most materials, but is it the right choice for building a supercar on a budget? That is the question we set out to answer in this video. We investigate the material properties that often get lumped together in being called "strength," to understand what is best and what the best might cost.

I love the methodical way you explain the engineering science behind this build and the rationale for your choice of materials 🙂
That was really good. Trade offs are always present, but your example was impressive to help us understand the development of the car body.
Jarvie, your patience and intelligence to explain a complicated concept in a simple way is memorable. but ... you as always bring us great answers. great job.
Loving this explanation. Thanks.
I love how this shows that you are not aiming to a luxury device, but to a damn good car.
Thanks for sharing your analysis of the differences of materials and thicknesses. This was so informative for someone looking to get into making composites.
Amazing level of detail . Love the work
Very well explained. I seem to have the same problem when explaining this to people regarding my project, but I'll just send them your video, as it would save me a lot of time. ;)
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)
VERY informative video!
I am making a body kit for my car (videos on my channel). I decided to go with the following: - epoxy resin (because I live in a hot climate, it will holdup better than polyester resin) - carbon fiber (because it will flex a lot more before breaking, compared to fiberglass) - Kevlar (outer layer of Kevlar to protect against rock chips and other road debris) epoxy (generally only used with carbon fiber & Kevlar, sometimes fiberglass cloth) polyester (pretty much only used with fiberglass, as the polyester resin has a chemical that breaks down binders in fiberglass) Over the past 3 years I've had a lot of exposure to fiberglass (cloth & CSM) with polyester resin. The final product is easily 3x heavier, and uses a lot more material to make (hence its heavy-ness), this also translates to minimal cost savings over carbon fiber (maybe 2/3 cheaper). in my experience, epoxy resin holds up a lot better to high temperatures (120+ F) over polyester resin. Polyester resin is brittle like glass, and will shatter when impacted. Epoxy resin is semi flexible. Epoxy tolerates high temperatures better than polyester. If polyester resin is exposed to high temperatures for extended amounts of time (maybe a few years) it will warp, epoxy resin will not. Kind of how i look at it.. Epoxy resin will out last human civilization in a land fill, polyester will not. So, if your going to make something that you want to last for many many many years, make it with epoxy. 😉

I took a look at your channel - looks like a great project. I am assuming with all the description in your comment, you are looking for verification of your process? If not, I guess you get to hear my" two cents" anyway. Ha! Unless you are going to be using carbon fiber for the aesthetics it is not going to be of benefit to you. In actuality the fiberglass is more "flexible" than carbon. Carbon fiber is used when you want little to no flexibility. As you have mentioned the carbon can be 4-5 times more expensive for the same area of cloth so you may have to add 4 times more layers of fiberglass to achieve the same stiffness, but as you also mentioned (especially with a rally car) you want a semi flexible panel. Which can be achieved with just less layers and stiffening with with topography/ architecture (as you did with tubing under your hood). Carbon fiber is also not going to gain you enough weight savings to justify the cost . . . unless you plan on stripping all the comfort and luxury items out of the car. (can we say air conditioning!) Ouch! Finally, Kevlar will be your friend only on the lower third of bottom panels. It will not protect you from rock chips, but will keep the panels together long enough for you to get home should you hit the neighbors cat at speed. Also remember if you want to get closer to carbon fiber performance characteristics for a fraction of the cost use S-glass fibers. Anyway that is my two cents. :) keep up the great work!

@@BuilderCreator Thanks for the reply and checking out my channel! I am certainly no expert on composites, and I am always grateful to learn new things. thanks again for taking the time to respond.
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.
Got there in the end * fibre glass is by far cheaper than carbon fibre lol👍🏼

Sure clear painted carbon fibre looks genuinely cooler then fiberglass. That said no one will see it when both cars have their paint jobs done on the body.
This vid is by far the best when comparing carbon fibre and fibre glass. We all get to see the test done. Very educational.
Pretty much nailed that across the board. I've had this conversation many a time to the event that it's just easier to point them towards certain materials engineering videos, but they still don't accept it. At that point, it's time to move along to more important ventures. =) In automotive history, Overweighting has also been called "Shelby the sh!t out of it" (power priority over less weight) and "Just Enzo it" (more engine, less aero work).
Thankyou VERY much for this video, you are a great, fair and honest teacher. Learned quite alot👍👍
Finding this video while researching for my own car project, as well as just having finished a material science course in industrial design is REALLY REALLY satisfying!!! Awesome video
Great episode Jay! Nice alternative to the E&N (ego & narcissism) supercar production model!
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.

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. Excellent video.

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.

How fast do you want to go, how much do you want to spend.
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

Given the figures you have presented I wouldn't build in carbon fibre. I agree there are many more useful ways to spend the difference in cost. Knowing me as I do I wouldn't spend the money on carbon fibre even if I had the money to spend on it. I think there is a price we need to put on a project no matter how important and interesting it is. Each part is important but not so important that it gets to dominate the whole budget. 😊

Apparently prone for going up in flames! I guess the tech and products have game along way along with the safety standards these days :D Cheers for clearing it up.
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.

In a crash or crush test, carbon fiber will always be on the bottom side of the outcome, (Kevlar on top with glass in the middle.) Carbon is chosen for its rigidity (stiffness) and ability to get to that stiffness with less weight. People always like to point out how a F1s monocoque tub is so strong and protective. Yes it is, but a Kevlar/glass tub of the same thickness would likely be stronger, but also 3 times heavier. (4 times heavier, when you reach the same stiffness) Something that counts in multi-million dollar racing world. If you can afford carbon in your project, then by all means go for it!
