From what I have read, carbon fiber on aircraft is used in conjunction with other structural components. It's a skin, glued and fastened to a framework of other materials. Like siding on your house, more a covering than a primary structural component.

One component of the article mentions that carbon fiber is less expensive than other materials. Doesn't seem that way to me in the bicycle industry. I wonder how much of the marketing push for carbon is based the possible 2000% markup?
