Jec Composite Award Winners
BROCHURE AWARD ASIA 2009 ok:COUV 12P AWARD 6/10/09 11:33 Page 1 BROCHURE AWARD ASIA 2009 ok:COUV 12P AWARD 6/10/09 11:33 Page 2 Edito Innovation is a winning strategy! Ever increasingly, businesses are facing change like never before. Numerous driving forces to this change include a rapidly expanding marketplace and increasing competition, diversity amongst consumers, and availability to new forms of technology. Creativity and innovation are undoubtedly key to success! The 2009 JEC Asia Innovations bring ground-breaking improvements in new materials and processes with the following distinctions for new materials: - nanotech composites blended with organic nano-particles for a one-piece “jointless” ice hockey stick with the right combination of opposing features – flex, band, stiffness and whip, - loaded surface tissues with increased anti-flame-smoke-toxicity qualities particularly for mass transit and building applications, - polyester concrete made from selected fine sand hardened by unsaturated polyester resin for production of pipes with excellent corrosion resistance and earthquake-proof properties, - vegetal fibers or matrix such as renewable cellulose reinforcement for a brand new environment-friendly surfboard. Concerning thermoplastics or thermosets processes: - a new technique of laser-assisted thermoplastic tape placement enabling the fully automatic production of light- weight components for the aerospace industry, - a new cost-effective application for radio telescopes which clearly demonstrates the potential of composite materials for the construction of radio antennas in the size range of 10 m to 15 m, - an application for wholly new-designed rail insulators for the airport rail lines connecting airports to downtown, - a new winding process for non axi-symmetric profiles with integral-end dome winding for tankers, - an application featuring special hulls made entirely out of carbon and glass fibers composites for ultra-fast interceptor boats. -

World Academy of Science, Engineering and Technology International Journal of Mechanical and Mechatronics Engineering Vol:7, No:1, 2013 Analysis of Failure Pressures of Composite Cylinders with a Polymer Liner of Type IV CNG Vessels A. Hocine, A. Ghouaoula, F. Kara Achira, and S.M. Medjdoub Gas storage consists of keeping the gas at room temperature Abstract—The present study deals with the analysis of the under pressure in a cylinder. The first tanks were type I, cylindrical part of a CNG storage vessel, combining a plastic entirely of metal would be too heavy for storage of CNG. liner and an over wrapped filament wound composite. Three kind of Storage cylinders for compressed natural gas (CNG) used in polymer are used in the present analysis: High density Polyethylene vehicles are pressure vessels that have been traditionally HDPE, Light low density Polyethylene LLDPE and finally blend of LLDPE/HDPE. The effect of the mechanical properties on the produced using isotropic materials, such as steel and aluminum behavior of type IV vessel may be then investigated. In the present [2]. paper, the effect of the order of the circumferential winding on the A notable improvement of this first technology is to stacking sequence may be then investigated. Based on mechanical reinforce the cylinder by filament winding composite just on considerations, the present model provides an exact solution for the cylindrical section (type II). Currently, two solutions have stresses and deformations on the cylindrical section of the given good satisfaction tanks type III metallic liner - vessel under thermo-mechanical static loading. The result show a good behavior of HDPE liner compared to the other plastic materials. -
Commingled Yarn Spinning for Thermoplastic/Glass Fiber Composites
fibers Article Commingled Yarn Spinning for Thermoplastic/Glass Fiber Composites Niclas Wiegand and Edith Mäder * Leibniz-Institut für Polymerforschung Dresden e.V., Dresden D-01069, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-351-465-8305 Academic Editor: Stephen C. Bondy Received: 25 April 2017; Accepted: 17 July 2017; Published: 20 July 2017 Abstract: Online commingled yarns were spun with three different polymeric matrices, namely polypropylene (PP), polyamide (PA) and polylactic acid (PLA) and glass fibers. Tailored sizings were applied for the three matrices and the resulting mechanical performance of unidirectional composites was evaluated and compared. Significant improvements in the fiber/matrix bonding were achieved by employed sizing chemistry in order to achieve multifunctional interphases. The pure silane coupling agents provide the best performance for all matrices investigated. However, an additional film former has to be added in order to achieve fiber processing. Film formers compatible to the matrices investigated were adapted. The consolidation behavior during isothermal molding was investigated for polypropylene matrix. Different fiber volume contents could be realized and the resulting mechanical properties were tested. Keywords: commingled yarns; Polypropylene; Polyamide; Polylactic Acid; sizing; glass fibers; thermoplastic composites; multifunctional interphase 1. Introduction Thermoplastic polymer matrices enable to manufacture composites at very short cycle times which makes them feasible for high volume productions. In contrast to thermosetting composites, they exhibit better impact resistance, higher toughness, recyclability and in the case of polylactic acid (PLA), even biodegradability. However, fiber impregnation is more difficult due to the high melt viscosity of the thermoplastic matrix. Different impregnation techniques have been proposed and performed. -

Manufacturing Flat and Cylindrical Laminates and Built up Structure Using Automated Thermoplastic Tape Laying, Fiber Placement, and Filament Winding
MANUFACTURING FLAT AND CYLINDRICAL LAMINATES AND BUILT UP STRUCTURE USING AUTOMATED THERMOPLASTIC TAPE LAYING, FIBER PLACEMENT, AND FILAMENT WINDING Mark A. Lamontia, Steve B. Funck, Mark B. Gruber, Ralph D. Cope, PhD, Brian J. Waibel, and Nanette M. Gopez Accudyne Systems, Inc., 134B Sandy Drive, Newark, DE, USA19713 ABSTRACT Automated thermoplastic filament winding, tape laying, and fiber placement have been demonstrated by manufacturing thermoplastic-reinforced carbon-fiber laminates and stiffened parts using in situ consolidation. Material feedstock requirements were met with polyimide and polyetherketone placement-grade tows and tapes from Cytec Engineered Materials. The thermoplastic in situ heads integrate material deposition with a polymer process that combines preheating, generation of layer-to-layer intimate contact, interlayer bond development by reptation healing, consolidation/squeeze flow, and freezing/void compression in the laminate. The in situ winding process combines sequential [0 °] tape laying and filament winding to fabricate [0 °/90 °] and [0 °/90 °/±θ°] monocoque and ring-stiffened cylinders from polyetherketone composite material systems with outstanding property translation. Finished parts and systems have been commercialized. The automated fiber placement process has been developed for flat skins with twelve simultaneous 6.35mm (0.25-in) tow placement or one 76mm (3-in) tape placement capability. Thermoplastic and cross-linking composites and coated titanium foils have been placed. A large number of demonstration parts have been fabricated including flat laminates with and without padups, stringer- and honeycomb-stiffened skins, and TiGr (interleaved Titanium and Gr aphite/thermoplastic layers) skins alone or sandwiching Titanium-honeycomb core. In general, 85% to 100% property translation is available with in situ processing, and 100% if post-autoclaved cured, for example to advance a cross-linking polyimide resin. -
