It doesn't. Bleat about it all you want, it doesn't make it true.
Carbon fiber is not elastic. It is not plastic. It fails catastrophically
with little elongation at all (~1.5%).
In the linear part of the stress strain graph, carbon fiber and Al alloys
have the same practical range before yield (~0.4%).
Check your facts at www.matweb.com and stop propagating myths.
Quoted message said:better specific modulus and superior fatigue, it's a better material on
three counts.
Only if you ignore the drawbacks of CF, which have been discussed to death
here already.
Quoted message said:the "brittle" argument is [censored] if you don't understand the failure
mode - cfrp does not shatter like glass.
Wow. Someone who has even a modicum of scientific training can understand
that "brittle" is perfectly applicable to carbon fiber, because CF does not
substantially elongate either in the "elastic" nor "plastic" sense before
failure (~ 1.5%). However, someone who does not have scientific training,
nor the ability to understand physical properties (and instead can only
parrot pop science sayings), can get fixated on having a very narrow and
inadequate definition of brittle (according to beamboyworld, only glass can
be brittle).
Quoted message said:what? peter cole [censored] on something he doesn't know about? surely that
would never happen!
Of course not. You, on the other hand, have the knck of doing it every
time...

typical peter cole. cherry pick the points you want to argue and ignore
the others that make them a crock. you're a bullshitter.
No, it's been clear for years that you're the lying, ignorant fraud who
thought bluster and abuse can cover up your lack of knowledge. Your time is
over, beamboy.
