What is carbon fiber?

When you heat glass enough to almost melt it, it becomes a gooey, gluey substance,

like very stiff slime. In that condition, it's rolled flat to make window-glass, or spun

on the end of a rod to make cups and bottles, or blown up like a balloon to make

bottles with very thin necks.

Also when glass is in that condition, if you grab a little pinch of it (with tongs!)

and slowly pull it away from the main glob, it stretches way out and becomes

very thin before it finally breaks. It can be stretched to where it almost has the

consistency of cotton candy or fine hair, and that's the material used in

fiberglass home insulation. When it's stretched not quite as thin as that, to the

thickness of a thick sewing thread or a nylon fishing line, it's quite flexible, and

in this condition, a plastic jacket is formed over it, just like a piece of wire, then

several of them are jacketed into a single cable and used for "fiberoptic" data

communication ... a pulsed bright infrared light, injected into one end with a

laser diode, travels very nicely through several miles of this glass thread to be

received at the other end of the cable.

So "fiberglass" is glass that's been melted and stretched until it's no thicker

than all those other things we've been calling "fiber" for hundreds of years.
