OCTOBER 2015 60 CompositesWorld this patented z-axis mechanical enhancement technology at CAMX. Via NanoStitch, nano- sized fbers can be "grown" perpendicular to and on the surface of a carbon fber prepreg, conveying to the prepreg surface a z-direction bonding point that substantially increases interlaminar shear strength (see photo, p. 59). N12 says shear, fracture, compression and fatigue performance of composite materials can be signifcantly enhanced by NanoStitch. N12 is scaling manufacturing capacity, testing materials for multiple OEM programs and collabo- rating with the world's leading prepreg composite suppliers to develop a full range of certifed NanoStitch-enhanced fber/resin systems. The company also is developing NanoStitch- enhanced products compatible with resin infusion techniques, thermoplastics and adhesives. N12 says it has more than 100 OEMs globally exploring and testing its technology and have now committed the capital through 2018 and beyond to build industrial-scale NanoStitch manufacturing capacity. www.n12technologies.com NDT Systems Inc. (Huntington Beach, CA, US) will feature its line of advanced ultrasonic testing equipment to the nondestructive testing (NDT) marketplace. These products include a variety of ultrasonic thickness gages, bond testers, portable faw detectors and a range of precision ultrasonic transducers and manual and automated scanners for the inspection of almost all materials, from advanced composite materials and plastics to ceramics and metals. The bond tester allows for rapid inspection of bond line integrity; imaging faw detectors give the advantage of area scanning with C-scan displays in an easy-to-use package. Customized solutions, including fully automated inspection solutions and specialized transducers, also are available. www.ndtsystems.com PPG Industries' (Pittsburgh, PA, US) fberglass business is introducing at CAMX its HYBON 2052 direct draw roving, designed for high- and low-pressure epoxy pipe applications and pressure vessels. It is compatible with amine- and anhydride-cured epoxy resin systems. HYBON 2052 is available in E-glass and E-CR glass compositions. PPG says the tailored chemistry, which uses an alkyl phenol ethox- ylate (APE)-free sizing system, ofers excellent fber/matrix interfacial hydrolysis resistance and strength retention. These products are currently produced in the US and are globally available in various TEX/YIELD options in flament diam- eters ranging from 16 to 23 microns. www.ppgfberglass.com Reichhold (Durham, NC, US) will launch its new ADVALITE vinyl hybrid resins, available in styrene-free liquid and monomer-free hot-melt prepreg versions. Both versions reportedly exhibit excellent mechanical properties with a rapid cure rate to reduce production cycle times. ADVALITE vinyl hybrid resins can be used in resin transfer molding (RTM), infusion, flament winding, liquid molding and pultrusion processes, directly coated or adhesive flmed for fber impregnation. During the CAMX conference, Reichhold's James A. Bono will present "Vinyl Hybrid Snap Cure Resin Applications in Filament Winding, RTM and Prepreg Processes"; Samuel Freeman will present "Studies on the Efect of Degree of Crosslinking of Vinyl/Acrylate Networks"; Anthony Skrobacki will present "Mechanical and Thermal Analysis of Toughened Rubber- Modifed Vinyl Ester"; and Hildeberto Nava will present, "Studies on the Reactivity of 1, 2-Vinyl Containing Liquid Rubbers in a Rubber Modifed Vinyl Ester." www.reichhold.com Sunstrand (Louisville, KY, US), a manufac- turer of natural fbers for polymer composite reinforcement and plastic fllers, says all Sunstrand products and processes have been designed to deliver consistent, high- quality fbers that are compatible with typical SHOW PREVIEW
