It's also interesting the carbon often goes in a woven fabric, in a lower modulus epoxy sauce.
And a Complete Waist of materials it is , when carbon is Woven .
It may look cool, but 30% of it's properties go Byby, the moment
Carbon + Kevlar or Spectra UNI , is about as Good as it gets ;
Boron is better ; but that stuff can Kill Ya !!
You are correct in terms of bending and buckling. when you've gotta carry stress in a direction, uni is the way to go.
That stated weave and inherent waviness is quite beneficial in off axis loading (perpendicular to the fibers) and impacts
if you have a softer core that your trying to keep from putting your foot through (like a kiteboard) or some highly stressed uni that can't get stone damage. Or simpler yet trying to keep your trophy wife's stiletto heels from going through the floor boards of your exotic car, those basket weaves can be beneficial while still providing useful stiffness that Kevlar would not. and it does it while looking awesome....which of course saves the weight of paint, (for those of you who are functionally obsessed.)
You'll usually see most suspension components on race cars finished with a layer or 2 of carbon weave. This is more than cosmetic.
Anyway back to the original topic, he wants better resistance to hard landings.
Wood core,( for the off axis loading) S-Glass for energy absorption during bending
