Q: Why go carbon fiber instead of a cheaper flare material?

Prepreg carbon with Kevlar backing gives you the width and coverage while staying lightweight, which matters on an EV where mass costs range. The autoclave process with integrated resin produces a stronger, lighter part than wet-layup alternatives, and you get to pick a gloss or satin finish that shows the weave. It’s the combination of low weight and real durability that justifies carbon over a heavier molded flare.
