I think the brain was reduced to paste before it could process the signals appropriately. 50ms is easily long enough for me to send several thumb presses to a stopwatch. Much like how you don’t know you really hurt yourself until the brain starts thinking about it.
The only way I see a material like carbon fiber potentially surviving repeated pressure cycles like this is in a spherical shape. Even then, it will eventually fail. Once you understand material properties and the physics behind things the world looks a lot less glamourous than movies.
