Could CentrAL Make Cfrp In The 787/A350 Obsolete?

Mon Oct 15, 2007 2:54 pm

Will CentrAL (Central Reinforced Aluminum) make CFRP obsolete?

According to researchers, CentrAL could reduce the weight of a wing by 20% over CFRP and despite using aluminum, be "virtually impervious to metal fatigue."

Granted, even Airbus couldn't get this new material in time on the A350, but what if there's already a second generation of composite airliners just around the corner past the 787 and A350?

As the name indicates, 'composite' materials are just that, blends of different materials.

Everyday cement is a composite in the true sense of the word.


I'm a quite sure we'll continue to see new and exciting materials engineered all the time.
There is always a grain of salt that must be taken with a new 'miracle' material though. Much time, energy and testing must be done.

Carbon has been in the world, and niches like sailing, for decades, but the process must be somewhat mature and workable before the benefits can be realized in mass production of airframes.


Good find though, there is so much exciting development going on in material sciences.

I would imagine it would depend on how flexible it is. It is also interesting they tout it for wings, and not fuselages.

Then again, wings would benefit both from lower weight and greater strength, allowing them to take greater aerodynamic and physical (fuel) loads.  thumbsup 

This would likely be very welcome for the 737RS and A320RS programs...

Quoting MD-90 (Thread starter):

I kind of doubt it. The information on CentrAL is a bit sketchy yet but it's unlikely to beat CFRP in all applications (just as CFRP doesn't beat metal in all applications). I'm very interested in their claim of higher strength than CFRP...for anything involving aluminum, that's a huge claim.

What exactly is the difference to GLARE which is also an Al based composite? Keep in mind, it is used in the A380 skin and claimed to be very fatigue resitant, too. And isn't GLARE developped in Delft (The Netherlands), too?

But anyway, congratulations to the scientists!

Cheers

I am guessing it is stronger then GLARE and might be more malleable, which would make it better for complex surfaces like wings.
