MATERIALS:Solvay Advanced Polymers‘ broad portfolio of KetaSpire® polyetheretherketone (PEEK) and AvaSpire® modified PEEK resins now includes five wear-resistant grades. These formulations provide an effective all-plastic alternative to more complex metal-based designs with rolling components for high-temperature friction and wear applications in lubricated and non-lubricated environments. The offering includes two KetaSpire PEEK products and three AvaSpire modified PEEK materials designed for high-performance injection molded applications, including seal rings, thrust washers, brake components, gears, and needle bearing replacements for the automotive, industrial, and heavy-duty equipment industries.KetaSpire PEEK is one of the industry’s most chemically resistant plastics, offering excellent strength, superior fatigue resistance, and a heat deflection temperature up to 315C (599F). In this product family, KT-820 SL30 is a graphite/carbon fiber/PTFE-filled grade for non-lubricated and lubricated applications. In non-lubricated environments, it features a limiting PV value (contact pressure times velocity) of 75,000 psi x fpm and exceptional ease of processing, according to Brian Stern, senior global automotive market manager for Solvay Advanced Polymers. The line also includes KT-820 SL45, a carbon fiber/PTFE grade for lubricated environments.
The AvaSpire line of proprietary PEEK-based compounds includes AV-755 SL45, a carbon fiber/graphite-filled grade for high load-bearing applications in lubricated environments. Two carbon fiber/graphite/PTFE-filled grades include AV-742 SL30 (high melt flow) and AV-722 SL30 (low melt flow) for both non-lubricated and lubricated environments. An important advantage of all AvaSpire grades is their comparable strength and modulus, and equivalent or better chemical resistance versus comparable PEEK grades at up to a 30 percent cost reduction.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
