DOES ANYONE KNOW WHAT CARbon fiber is? Modulus graphite? Boron? They used to put boron into gasoline, or at least into gasoline ads. Now it goes into wildly technological golf clubs and tennis racquets. Or is that argon? Or titanium? Neither of which is to be confused with something called Kevlar -- the stuff they make bullet-proof vests from. Kevlar these days is a very hot item. There are bulletproof Kevlar canoes, for example. And water skis. And bicycle tights. (A lie: the Kevlar bike tights, for the moment, are imaginary. But remember, you saw them here first.) The rest...
That was great, but that was then. The Vortex is all but history. And the aerospace industry, beset by peace and recession, has not brought out any dark-of-the-moon materials in the last couple of years. High-impact modulus- polymer-visco-graphite is just as good as it ever was, but the new has worn off. This year's Prince entry in the country-club weapons race is called the Extender. Made of graphite and liquid crystal polymer, the Extender is bigger than the usual big-head (116 sq. in. vs. 110), and its oval shape is supposed...
