Aerospace +prostock = exotic materials

[sparky]

Over the years it seams that when exotic materials get released to the public through goverment surplus or just becomes out dated to them ,ends up in race cars . ,magnesum {sp}, titanium , carbon fibre ,kevlar, exotic coatings .
What do you think the next wave of exotic materials will be and used where ?To me it seamed that they mostly show up in pro stock first ?

 

[----NONE----]

That's a good question. I would say Pro Stock also, but then with the new ADRL classes and the street car racing, there's a good chance that it could end up in one of those. There's a bunch of guys throwing some serious cash around in those classes, almost like Pro Stock.

Carbon Nanotube push rods perhaps?

Unobtanium

Unobtanium

How much do you want?

Unobtainium - Wikipedia, the free encyclopedia

For example, a pulley made of unobtainium might be massless and frictionless.

Sounds to me like, the more you buy, the less you have!

Anyone know what is the name of the latest material used for making exhaust valves? (not titanium)

Also, where in the race car is "inconel" used?

Let's see-spending megabucks on exotic pushroods or building overhead 4 valve motors that don't need pushrods? Which one sounds more high tech to you?

Waaay too many years ago, late fifties through middle sixties, Inconel was used on the X-15 rocket plane for high temperature steel applications: skin, etc. Titanium technology was not commerically available yet for large structure.


Inconel - Wikipedia, the free encyclopedia

Uses
Inconel is often encountered in extreme environments. It is common in gas turbine blades, seals, and combustors, as well as turbocharger rotors and seals, high temperature fasteners, chemical processing and pressure vessels, heat exchanger tubing, steam generators in nuclear pressurized water reactors, natural gas progressing with contaminants such as H2S and CO2, firearm sound suppressor blast baffles, and Formula One exhaust systems.[6][7][8]

North American Aviation constructed the skin of the X-15 rocket plane out of an Inconel alloy known as "Inconel X".[9]

Paul, Inconel is a real hard to machine metal that can take lots of heat.

When I was in the aerospace industry, one of the shops I worked in made components for AirResearch using Inconel for the impellers in turbos. Inconel is pretty dense material so it's use would be limited by it's weight.

 

[BaldyLochs]

Well, I am in the aerospace industry. Corporate jet charter/maintenance to be exact. And unless the millions of people in this industry start standing thier ground, grow a set of gonads, and speak up against the ridiculous political and media bloodbath going on against us right now... you might see alot morematerials become available and more factories shutting down. There's quite a few start-up/next gen Very Light Jet manufacturers out there who are calling it quits - and they all were working with cutting-edge composite materials.

 

[Buzzz Miller]

what they were calling "Glassy metal" won't be around for a while, but when it is in our hands, it will have some great uses.

Mimetic Polyalloy AKA Liquid Metal.

I seem to remember Warren Johnson busting a driveshaft (carbon fiber?)a few years back-he said the ends were bonded with the same glue used to keep the tiles on the shuttle!
George Bryce had the ability to ad alot of ballast when Angelle started to ride for him. The balast? Depleated Uranium!

Hey paul, Inconel is still the perferred metal to use in the performance exhaust valves. As you've already heard its a very dense material and its resistance to abrasion and heat is also why it is preferred to use....

I've seen beryllium pop up in the last 5 years in race car technology, but I wont say who's used it and for what for obvious reasons.

 

[Nick Name]

Most everything mentioned here has been around for a long time.

Beryllium, for example, has been used in valve seats for decades.

I have built carbon fiber pushrods for an NHRA Pro Stock team and Nascar team in a cooperation with Manton Pushrods. We had some good results and then had them deemed illegal in both series. The weight of the pushrod is lighter, but the real benefit is that they absorb the valve train harmonics. This stops alot have the valve spring breakage that happens.

I have done quite a few carbon fiber drivelines, and they can take gobs of torque... they just don't really like the shock impact during the launch. If we preloaded the driveline, by applying the rear brakes to prevent the snap action, then we were fine and wouldn't shear the yokes off.

In the carbon fiber world, I haven't tested a nano tube material that has lived up to its printed hype. The best material only had a 12% increase in shear strength and the batch of material had a horrible consistancy of only 38%. If they can find a way to properly disperse the nano tubes into the resin in a cross matrix that is consistant, it may the real next new thing.

I am banking on graphite platelets, that so far in testing, has increased strength 64%. This is where my next new products are going to be designed with.

Just my $.02

graphite platelets? is that something you apply into the resin when your forming the carbon fiber?

Don't have a rulebook at hand but 3M has been marketing metal matrix pushrods for a while (and driveshafts). Don't know if they've been deemed illegal or not -also saw a blurb about Polymer Matrix Pushrods recently - am clueless as to what they are -didn't pass organic chemistry- but it's a cool term you could pass around in the bar after the races.

What ever happend to Saphire filamets - saw a bit on them in National GEOGRAPHIC -you heard it right - (not to be confused with that high tech publication, National Dragster) years ago.
