According to a recent report by Aerostrategy Management Consulting, spending by air transport maintenance and repair organizations (MROs) worldwide totaled $40.8 billion (USD) in 2006. Moreover, Aerostrategy (Ann Arbor, Mich. and Amersham, Buckinghamshire, U.K.) reports that spending on air transport maintenance

Quartz fibers, while more expensive than glass, have lower density, higher strength and higher stiffness than E-glass, and about twice the elongation-to-break, making them a good choice where durability is a priority. Quartz fibers also have a near-zero CTE; they can maintain their performance properties under

In his book by the same name, Malcom Gladwell describes The Tipping Point as “that magical moment when an idea, trend or social behavior crosses a threshold, tips and spreads like wildfire.” After decades of strong growth driven by a desire for improved performance, high-performance composites have arrived at the

Phenolics were the first commercialized thermosetting resins made from synthetic components. The earliest phenolic resin — polyoxybenzylmethylenglycolanhydride, formed from phenol (carbolic acid) and formaldehyde — is credited to Dr. Leo Baekeland, a Belgian immigrant to the U.S., although German chemist Adolf von

During the 1973 Arab-Israeli War, the Arab oil-producing countries imposed an embargo on customers friendly to Israel. There were long lines and high prices at U.S. gas pumps, and the airlines were paying more for fuel as well. The airlines complained to Senator Barry Goldwater, who was a pilot and a member of the
