One more evidence that home made carbon fiber it's a garbage, if compared to the proposed 4x stronger than steel clains we always heard on TV.
The usual lame crap excuse many carbon fiber home made people said is : It have just few layers".
But in this video, in you response to the comments, the guy said it had 3mm or 4mm.
Honestly if was a 3mm or 4mm steel plate it would not broke by a person with strong hands.
And if carbon fiber is at least 3 times stronger than steel, it's like he was broking a 9 mm or 12mm tick steel plate at least.
I still challenge someone to prove me that a home made carbon fiber is stronger than steel. Right now for me, based in these videos, it's just crap.
