Dow-United Technologies Composite Products Inc. has developed a patented process for using braided composites to make jet engine thrust reversers, the devices that slow aircraft during landing. In the past, the primary section of the reversers, cascades, was made from magnesium castings or from aluminum, making the multi-part structures comparatively heavy and susceptible to fatigue or stress failure at critical points. The Dow-UT process uses braided carbon fibers and resins to create a much lighter part with substantially greater strength at the joints. In addition, the part comes off the assembly line as a single component, reducing ultimate assembly requirements, according to Lawrence Varholak, Dow-UT vice president, engineering and technology. The patent represents an enhancement of Dow-UT's Advanced Resin Transfer Molding (AdvRTM(TM)) process. FAX (203) 949-5009.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isnít a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
