Aerospace Advanced Composites in AutomobilesThere is currently very little potential for advanced-composite technology in high-volume automotive applications. In the United States and Europe, the barrier to acceptance of advanced composites in the automotive industry is price vs. performance. What Is Bulk Metallic Glass?Bulk metallic glass, a.k.a. amorphous metal, appears to have a very bright future. Being twice as strong as titanium, tougher and more elastic than ceramics, and having excellent wear and corrosion resistance makes them attractive for a variety of applications. It can even be cast in a mold to near net shapes. Daubert Having Little Effect on Expert Witness ConsultingThe Daubert ruling of 1993 seems to have had more of an influence on the frequency and techniques that attorneys use to challenge opposing expert's testimony instead of verifying the science being used. Product Focus: Passive Radio Frequency IdentificationA new technology has been rolling onto the scene that can be used to replace or enhance the bar code, that of radio frequency identification (RFID). Radio Frequency Welding of PlasticsRF welding is a basic technology, and the basic devices necessary to affect such a weld have not changed since the inception of the process. The area where most of the technological changes have taken place is in the components from which the individual devices are constructed. Surface Treatment of Polypropylene Films for Printing and CoatingPolypropylene has a low surface energy and weak boundary layer making it difficult for inks and coatings to adhere to it. Therefore the surface must be properly treated before trying to print, metallize, or laminate to polyproylene. Current State of Joint Integrity Technology for Threaded FastenersThe assembly business will be revolutionized as ultrasonic control technology starts to displace the torque control methods in major automotive companies around the world. This will change the competitive focus of the tool companies, just as the electric driven tools have changed the business over previous years. Assessment of Battery Smart and Pulse ChargingThe rapid growth of battery systems for portable power of computers, communications devices, tools and entertainment devices has created a need for better batteries and better electronics for charging these batteries. Moving From Round to Flat in Automotive Wire HarnessesMultiplexing of electrical signals in automobiles is beginning to be used as vehicles are continually being designed with more electronics and options. Coming hand-in-hand with multiplexing is the use of flex circuits and flat flexible cable (FFC) to replace wiring harnesses. Aluminum Anodizing Technology and Market AssessmentThe strongest growth category for anodized aluminum appears to be that of transportation. An expected increase in the production of new aircraft to replace aging fleets and the auto industry's trend of increasing the use of aluminum for vehicle frames and bodies are expected to be the primary drivers of this growth.
