    Vacuum bag vs bolt force (fabricating a carbon fiber wing)

    Hello, thanks in advance. I'm trying to make a near 100% solid carbon fiber wing. I'm vacuum bagging the top half of the wing and the bottom half of the wing separate. After making sure there is a thin 2mm gap b/w the center of both halves the goal is to put a very strong, thick epoxy between...

    Can I mix carbon fiber fabric with most glues?

    I have a fragile plastic piece and I would like to coat the inner walls with carbon fiber, so I was thinking I could lay carbon fiber on it and put some glue from the hardware store to mix with it. Would it work in making it stronger or do I need a special glue?

    Cooling for Underwater Monitor Housing

    Hi, I have an underwater monitor housing made out of carbon fiber and an acryllic Glass on the other side. Over time the monitor heats up. I guess carbon fiber is a bad heat conductor :(. the Acryllic glass is almost 1cm thick. Does anybody have an advice on how to cool something like this...

    Automotive Why is carbon fiber safer than steel for the cars?

    Not just for carbon fiber vs steel, I went to a seminar and heard that the team was researching how to make the steel sheets used for car making to be 'stronger', so that, a car can be safer using their material. Then, when I asked what does it actually mean when they say their improved steel...

    Water jet cuttng carbon fiber fabric

    Hello! I've just received information that there may be a requirement to cut some carbon fiber fabric on the water jet machine in our lab. The party that wants the cutting done, requires an option that's quicker than using shears to cut it. That's pretty much all the information I have at the...

    Carbon Fiber Strip Buckling Force Problem

    Hey, So I`ve been trying to wrap my mind on how to solve this problem. I`m trying to use a CFRP Sheet as sort of a spring actuator by using it`s buckling phenomena to deliver a force to the body it`s attached to. Kind of vague so here is a video: This video does it electrically, but I...

    Carbon fiber raw strength vs laminates

    If raw carbon fiber has strength of say 4000 mpa, how come it is reduced when put in epoxy laminate to become only 950 mpa?

    Polymer with high Coefficient of Friction to Carbon Fiber

    Hey all, I'm trying to design a clamp that has to hold onto a hollow carbon fiber tube, approximately 2.5 inches in diameter. The clamp will be bearing a 15-20lb load. The carbon fiber will be at angles from 20-70 degrees from a vertical axis. I'm curious if there is a polymer that can be...

    Carbon Fiber or Fiberglass rope/ribbon?

    Hi guys, I was wondering if it is possible to use raw carbon fiber or fiberglass fibers without any sort of binder or adhesive epoxy in a rope or an unidirectional ribbon as long as the load is uniform, predictable, and in one direction. I think it would be less vulnerable to crack...

    Auto/Motor Feasibility of a carbon fiber chassis (DIY car design)

    Hey everybody, a couple years ago, I came across the top gear video for the Arial atom: a ~1000 lbs road legal 'go-cart' with a supercharged I-4 engine with a power to weight ratio of 600HP/Ton. Even though the body is already light, I would love too (once I get the time and resources) build...

    How Thick Should Carbon Fiber Springs Be to Withstand a 200-Pound Impact?

    Hello this is me first post on here i don't know if this would be the right section but I'm trying to design and build this spring to only deflect 2-2.5 inches the force on it will be 200 pounds falling from 6 feet and coming down on the the two circles. my problem is i need to learn how to...

    Expansion rate of Carbon Fiber vs Steel

    I am a lisc. Auto body tech, and I have a customer who wants a Carbon Fiber roof on a Volkwagen bug, I can fabricate a inner frame, and bonding will not be an issue, (according to paint rep) The hard part is I want to do a flush seem and have paint blend into carbon fiber. I will "butt" match...

    Applications for optimized carbon fiber composites

    Hi, for a University project I need to find areas of application for a special carbon fibre composite design process. This process makes it possible to optimize several properties of the carbon composite at once. For example it is possible to develop structures that provide several...

    Will a Carbon Fiber Car Frame Affect the Handling of My Electric Mini Cooper?

    hi, I've been toying with the idea of converting my mini cooper to an electric car, and I'm brainstorming ways to reduce the weight as much as possible. I came up with the idea of a carbon fiber frame to replace the heavy steel one, I found a company that can do it for me, but I was wondering...

    Can Carbon Fiber Revolutionize Mass Car Production?

    http://news.blogs.cnn.com/2011/03/09/japanese-company-announces-breakthrough-in-carbon-fiber-technology/ Is this really feasible? I was under the impression that mass production of carbon fiber structures like this was still too slow and the fiber too expensive to make? Obviously I'm...

    I need the acoustic properties of all materials more specifically carbon fiber

    Does anybody know the acoustic properties of carbon fiber. I've used google extensively but I've had no success. Is there a well known reference book within the materials engineering realm that gives the sound absorption coefficient (also known as the Noise Reduction Coefficient (NRC)) of varius...

    Can carbon fiber make a better bulletproof vest?

    Hey all, I wonder if anyone can answer this for me: Why hasn't carbon fiber been used to make better bulletproof vests (ignoring cost)? Doesn't carbon fiber have a higher tensile strength than Kevlar? Isn't it lighter? Also, wouldn't a solid version, of carbon fiber reinforced plastic...
