But metals are dense and have much weight per unit volume. This weight adds to the bulk of the vehicle, making it sluggish, as well as unnecessarily increasing the consumption of fuel. One of the first automobiles to have a composite body was the Corvette sports car. Introduced in 1953, the Corvette had a fiberglass body. Aircraft manufacturers have also been turning to composites for the same reason, using less aluminum and more composites. Military jets, which rely on speed and maneuverability, contain a lot of composites—in many cases, about a third of the craft—and about half of Boeing’s new 787 airliners will be made from composite material.

17 1 chemistry As described in the following sidebar, the result is a family of related chemicals, ready to be tested. Combinatorial chemistry produces hundreds or possibly thousands of candidate compounds to screen for the desired properties. One may fit the bill, or come close, in which case it may be further modified and retested. Drug manufacturers often use combinatorial chemistry in conjunction with other methods to create testable candidates for medicinal activity. The section titled “Hitting the Target—Discovering and Designing New Medications” on page 25 describes drug development and design in more detail.
