Why carbon fiber has light/white stripes on it? Why is it not completely black?
In: Chemistry
Carbon fiber is weaved together like a textile and then bind by a polymer. It’s not the completely one color because depending on the weaving, the fiber will be closer or further away from the edge of the polymer. The difference in depth mean that there will be a difference in light reflection which make it look darker or lighter to us.
The actual pattern will depend on the weaving pattern, but it will always be of different shade unless the polymer would be dyed black. But even if they could totally do that, why would they? I mean the pattern is kind of a marketing tool at this point. It look cool and serve as kind of a prove to the customer that it is indeed carbon fiber. All black carbon fiber with dyed polymer would probably sell less.

Carbon fiber on its own is just that, fiber, like twine. You need resin or glue to hold it together to make something. That’s what the white shiny part is
Carbon is funny. The same element can be coal black (coal) or gray (graphite) or transparent (diamond). All are pure carbon, just the atoms are arranged in a different shape (allotrope).
