CAMX 2017 preview: Engineered Fibers Technology
Appears in Print as: 'Precision-Cut Fibers for Pelletized Thermoplastic and More'
Engineered Fibers Technology LLC (EFT, Shelton, Connecticut) is exhibiting a range of its precision short-cut fibers with lengths of 0.10 mm to several centimeters. EFT provides fibers tailored to a customer’s engineering application. Available short-cut fibers include carbon fibers, nickel- and metal-coated carbon fibers, quartz, S-2 glass, basalt, stainless steel and ceramic fibers. Polymeric short-cut fibers include PEEK, PEI (Ultem), PPS, aramid (para and meta), PTFE, Vectran LCP, cellulosic (BioMidTM), PLA, PVOH, high-tenacity polyester and microdenier and bicomponent fibers, among others. EFT is introducing two grades of a new short-cut, high-silica glass fiber with textile softness for high-temperature applications. Coated Short-Cut Fiber Strands with Engineered Strand Integrity (ESI) are among the most recent product additions from EFT. A range of coatings including polyurethane, phenoxy, epoxy, polypropylene and other specialty materials can be applied to various filament yarns such as carbon, glass, basalt, quartz, and polymeric fibers. After cutting, these free-flowing fiber pellets are designed for fiber conveying and improved matrix adhesion when used in fiber reinforced composites. EFT also is exhibiting EFTec Nanofibrillated Fibers produced from biodegradable, naturally sustainable and synthetic materials including: Lyocell, regenerated cellulose, PAN, aramid and Vectran LCP. The nanofibrillation process produces fiber diameters equal to those observed in electrospinning and melt spinning nanofibers and nanofiber webs. An entangled branch structure with a broad distribution of microfiber/microfibril diameters results in good bonding, anchoring and microporous filtration. Spectracarb porous graphite papers and panels with thicknesses of 0.1 mm to more than 4 mm are also on display. These panels are a key element of electrochemical devices including fuel cells, electrolyzers and flow battery technologies. Booth C81.
The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.
Yes, advanced forms are in development, but has the technology progressed enough to make the business case?
Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
