DuPont™ Kalrez® and Vespel® high performance parts are used in demanding aerospace and aircraft engines.

DuPont™ Kalrez® and DuPont™ Vespel® high performance parts have provided innovative solutions to complex aerospace sealing, wear and friction challenges at high temperatures for over 45 years. Kalrez® perfluoroelastomer parts are used as oil seals in turbine and jet engines and air delivery systems. Vespel® parts offer very high temperature capability, wear resistance, and low friction to effectively replace metallic materials.

“DuPont tests with Kalrez® AeroSeal™ 7800 parts demonstrate low corrosion in titanium and steel for 1000 hours @ 250 °C with excellent compression set resistance, and offer a maximum service temperature of 325 °C”, says Mark Schmeckpeper, global aerospace marketing manager DuPont™ Kalrez® and Vespel®. And he continues: “Our equally new Vespel® ASB-0670 parts perform in very demanding conditions. They can be found in blade wear strips, where friction and load create high stress. They provide improved wear resistance and a low coefficient of friction compared to other polyimides over a wide range of temperatures. In DuPont wear tests, that have been confirmed by customer tests, Vespel® ASB-0670 parts have shown exceptional performance.”

Polyimides Improve Wear Resistance, Reduce Weight

Vespel® SCP parts, which debuted at Paris Air Show in 2011, provide improved wear resistance at elevated temperatures and a low coefficient of friction compared to earlier polyimides. In applications where non-metallic materials have never been widely used, engineers are relying on the high-temperature capabilities and wear resistance of Vespel® SCP parts to replace metal, thus saving weight and improving fuel effiency. “SCP parts are a key reason why we’re gaining more and more approvals for use in aircraft systems in wear applications, including bumpers, wear pads, bushings, seals and shrouds,” said Schmeckpeper. Vespel® SCP parts typically weigh 75 to 80 percent less than stainless steel and substantially less than aluminum or titanium components.

DuPont™ Kalrez® and Vespel® high-performance parts provide innovative solutions to aerospace designers and specifiers when complex sealing, wear or friction difficulties are encountered.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
