@@Reman1975 Well, they could've at least made a decent mould. They could've waxed the freakin mould and apply release agent. It's not difficult! But... they used a bent conrod for the mould. The mould itself was a disaster. The layers were not wetted after being applied. The fibre orientation was all over the place. The resin infusion was wrong from start to finish (the mid centre layers were bone dry). No steel insert on the small end... and so on. Composites are not quantum physics. Even when working with limited equipment, common sense still applies.

Yes, they did have a reputation of slop from the beginning, but that would stay the same till it rusted apart.

Plus so cheap that you had no worries about damaging it, your Lada was cheaper than repairing the Land Cruiser, and you could just panel beat it back into rough shape, and carry on. Plus the engine bay you could climb in to to work on the engine, and the full size spare, high lift jack, good tool kit and starter handle were standard. OK not the fastest, or the lightest on fuel, but had a really good heater, and AC you opened the window. Still a fair number of them running around, rust in close formation.

The strength of carbon fibre composite is in tailoring the layup to resist the stresses; you need to wrap the fibre around the eye (a metal insert fitted at the start of the layup). Similarly with the big end, fit metal inserts for the bolts, and wrap the fibres around those tubes to hold everything together, as well as wrapping around the bearing cap and along the length of the rod. You really need to use something like FEA to figure out how much fibre to wrap in which direction. It's like forged rods are stronger than cast, because the forging adds strength in the direction of the parts but cast is the same strength in all directions, which is down to the size and orientation of the crystalline structure.
@Jupiter__001_2 жыл бұрын
Carbon fibre struggles to deal with the oily, hot environment, and its porosity can result in the churning of the oil. Also, its lack of density (which is also what makes it so light compared to metal parts of the same size) means it needs to have less compact parts, despite its high strength to weight ratio. The latter problem is what happened here.

Wow that was interesting, reminded me of my engine build in 1966 a 1957 Olds for my 1947 Chevy. Carbon Fiber ?? I had used Carbon Fiber 1st in 1978 for CT Scanner patient support. It was fairly translucent to Xray and Stiff as well. But that was a static part. In 1985 I used Carbon Fiber again for a robotic arm for a large industrial welder. Light weight, stiff and easy to control Vibration. But not heated or seriously stressed in small joints. The Connecting rod as we saw; Has a lot of stress at the fasteners, and heat from the engine and bidirectional forces changing direction rapidly. It's a really serious strength test for any material. Certainly you picked up on the need for design change required to add material at the stress point. Thicker wider wrist pin and rod bolt areas. But using a whole-strand has strength mostly in compression. It relies on the resin to handle other forces. In one project the Navy needed tougher Buoys for the sea environment. They tried Carbon Fiber but needed it to be lighter. The used Mirco-glass bubbles mixed in with the resin for lighter weight but still strong enough, it worked. I used those micro spheres to reduce X Ray absorbing on the thick edges of the patient support/ It worked! Now in the case of Connecting rods I would think if Automakers can press connecting rods from Powdered Metal. You could mix powdered metal into the resin for added strength to the Rod overall and then instead of a weak vacuum, use something like an autoclave to heat cure under very high pressure the rod assembly. Now with added material in the weaker points (wrist pin and rod bolts) plus powdered Metal in the Resin and High pressure curing You just might have a Connecting Rod that could handle a gas engine. for fun. how about a carbon fiber Housing for an electric motor and see if you can replace the gas engine with carbon Fiber Electric Motor. Save the Planet but still build fun cars with powerful engines and motors. Stay safe, Stay well, keep thinking and doing, what else do we live for. Dennis in Virginia

Compared to steel, Carbon is 3x-4x 'stronger', in terms of ultimate and yield strength under a compressive load.... But it is not nearly as 'tough'. Steel can take more of a beating, since it isn't as stiff. It can spring. Carbon is too brittle, and I think a thicker connecting rod would have the same results. Carbon is ideal in a situation where it is constantly loaded, (bearing strength is incredibly high) but going from nearly no load on the exhaust stroke/intake stroke to very high compressive load on compression/power stroke is making the worst property of carbon come out: it is brittle. Also, the crank is balanced and counterweighted for a much heavier connecting rod. This extra vibration from the crank is not good for brittle carbon.
@spankthemonkey34372 жыл бұрын
I think the rods would work if they did like a giant chunk of carbon fiber kinda like a billet piece compress it to like 30,000 psi to dry and machine it down. Then also figure out a way to add say an aluminum bearing housing inside the rod to hold the bearing still better. It would definitely require some science behind getting the piece of aluminum inside the mold in exact spot. And some kind of demples or short spikes to hold bearing housing still inside rod then actual bearings could be inserted. Or the bearing could actually be what I called bearing housing too.

By real, hydraulic pressing is involved, normally starting at the 100 ton level. It is definitely easier to use for complex shapes like this connecting rod, aside from the actual laying part as it gets attached to your gloves and such during manual layup. You just stuff it into a mold, having measured for resin to carbon ratio ahead of time.

It's impressive that you were able to make these in your own shop and have them last any length of time. There are carbon fiber con-rods on the market. But, they are very rare, very expensive, and not intended for street use at this time. After seeing carbon fiber brake rotors and pads, I figured it was only a matter of time before something like engine components would make their way onto the scene.

@Robert-xt5gx2 жыл бұрын
Fundamental problem here is the loading on the connecting rod and the material properties of carbon fiber. At TDC the force transmitted through the rod is compressive. Carbon fiber offers virtually no strength or stiffness in the compressive axial direction. In compression, the strength and stiffness is nearly 100% derived from the matrix (epoxy generally). While the carbon would offer some benefit in the bending stresses of the beam while the crankshaft is at 90 and 270 degrees the compressive force needs to be addressed.

It will probably require 2 molds in combination to form the 2 halves properly with vacuum and heat to cure properly. Also you may need to make it thicker in material initially before any machining is done. The whole thing needs be made into as solid of a piece as humanly possible to ever stand a chance. Cross layering is essential for strength to carbon fiber.

This is a perfect example of how an excellent material for one application, may be terrible for another. I believe the problem is the polymer melts at too low of a temperature. Carbon fiber may be able to be used in high temperature engine components if it's combined with a high temperature material (metal perhaps? Don't even know if that's possible) regardless thanks for trying it guys! It's cool to see what actually happened.

There are some top fuel drag cars experimenting with carbon fiber con rods. They are able to handle upwards of 10,000 hp. The carbon fiber definitely has the ability to handle the stresses, but it has to be made with a lot of care. I think the best way to make conrods with available equipment is to use forged carbon with continuous strands laid in the direction of the conrod, and then using a press to squeeze the mold.

@tommurphy91472 жыл бұрын
Try a design using 2x2 twill each lay 45degree to each other, sandwiched with some random fibre patterns. Also use resin infusion method which will give you a tight lamination and a better fibre to matrix ratio (you can even use an autoclave to add additional atmospheres onto the part when under vacuum and heat if using pre preg) for what you are doing you need the best ratio possible due to to the matrix being brittle and the fibre flexible having a bad fibre to matrix will make the part too brittle as it was. The main issue is that composites hate being In compression and when compressed delaminate once they have started to delaminate all strength is lost and they rapidly fail.

The big issue is heat. The start up was clearly fine by the time the engine warmed up (which is normally between 180℉ to 230℉), it melted the hard plastic-like bonds that held the fibers together and that’s why it shredded into pieces.

If you are going to do carbon fiber then you might have to change how its formed. Carbon fiber belting! Take a long narrow ribbon of carbon fiber and wrap it around the area of the pin and bearing then pinch the center like pinching a timing belt around 2 pulleys to remove slack and wrap carbon fiber around the pinched area to bind it. Should be the strongest form and remove the chance of destruction as easily from the bolt tear out. Problem is they would have to be made onto the crank. It would have to be a multipiece crank assembly like what they can get away with on some air compressors.

Needs different resin, one that can hold at very high temperatures and work with oil, there are some that can hold up top 400°C or alternatively Carbon Fiber cloth with impregnated high temp resin. You also need alot of more layers to make solid carbon fiber piece with alternating weave direction. But what you did with your knowledge was very nice.
