MATERIALS: Simrit, the industrial products division of Freudenberg-NOK, recently expanded its material product line with the debut of the F273 material for the aerospace industry. The new material conforms to all requirements of AMS-7273. F273 fluorosilicone rubber products are manufactured at Simrit’s International Seal® facility located in Santa Ana, CA.
The F273 material is used in high-performance, high-pressure jet fuel systems and is resistant to jet fuels and synthetic turbine lubricants with a typical application temperature range from -70 to 200C. The AMS-7273 specification is difficult to meet because of stringent requirements for aged properties - meaning that no appreciable property changes are allowed at exposure temperatures up to 200C in dry heat. Additionally, this specification is difficult to meet with the high-pressure, extreme temperature simulated component testing in fuel.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
