JEC Composites 2007 Product Showcase
The annual JEC COMPOSITES Show underscored the health of the composites industry and its global expansion: More than 1,000 exhibitors — the largest number ever at a composites trade event — and thousands of composites industry professionals converged on the Paris Expo in Porte de Versailles, Paris, France (April 3-5) for three days of networking, education and composites industry commerce. Organizers called it the most international JEC show on record, reporting that 65 percent of visitors and 70 percent of exhibitors came from outside France.
CT staffers were on hand and found a wealth of new materials and other technical developments on the expanded 40,000m² (430,556 ft²) JEC show floor. Among the headliners at this year’s exhibition were groundbreaking composites applications, particularly in the fields of high-performance motorsports and infrastructure. The show-floor buzz also included announcements of acquisitions, development and/or marketing partnerships and myriad new materials, processing equipment and services, of which the following is a representative sampling.
Advanced Composites Group Ltd. (ACG, Heanor, Derbyshire, U.K.) announced that it will collaborate with GrafTech International Ltd. (Parma, Ohio) to sell GrafTech’s carbon foam block in combination with ACG tooling prepregs on the tool surface. Under another agreement, ACG has launched ACG TB720, a standard-grade epoxy tooling board developed with Huntsman Advanced Materials (The Woodlands, Texas).

Alcan Composites (Sins, Switzerland) showed its AIREX and BALTEK products, including new AIREX C52 industrial processing foam, which replaces KAPEX C51. With a perforated polyester fleece top layer, the new foam reduces resin consumption during processing while still providing the same adhesion properties with composite skins. In keeping with its two-brand strategy — AIREX and BALTEK balsa cores — the trade name KAPEX has been phased out, says the company.
Aptiform (Chesterfield, U.K.), launched at JEC its new line of self-reinforced polyethylene terephthalate (PET) materials — a PET resin reinforced with PET fibers — joining the self-reinforced polypropylene the company already provides. Aptiform emphasizes that PET is easily painted and bonded and offers weight savings compared to glass-reinforced plastics. Also, because the fiber and the resin are the same material, recycling is easier.
Arkema (Paris La Defense, France) showcased its acrylic block copolymers, dubbed Nanostrength, which are used in formulation of epoxy resins and adhesives. The company states that the copolymers provide excellent toughening without compromising the epoxy formulation’s thermal performance or solvent resistance.
Asamer Basaltic Fibers GmbH (Ohlsdorf, Austria) introduced for the first time anywhere its ASA.TEC brand of basalt fibers. The company is part of the larger Asamer Group, which owns and operates more than 20 quarries located throughout Europe from which basalt rock can be sourced. This, says the manufacturer, allows it to customize chemical compositions in the fiber to meet specific application goals. Asamer also says it sources the fibers in cooperation with the Ukrainian firm TZI.
Ashland Performance Materials, Composite Polymers (Dublin, Ohio) introduced to Europe its POLARIS line of resins for cast marble, solid surface and engineered stone applications. Polaris, already available in the U.S., is said to offer low water absorption, low color and high filler loading capacity. Used in solid surface applications, products produced with POLARIS resins meet the ANSI Z124.6 standard.

EMS-GRILTECH (Ems, Switzerland), subsidiary of EMS-CHEMIE, got some attention at the show with the introduction of Grilon MS, a matrix-soluble auxiliary yarn spun from low-melting phenoxy copolymers. Described as an thermal adhesive in yarn form, this product is compatible with epoxy resins and can be used for weaving or braiding, to stabilize dry reinforcing structures such as unidirectional fabrics and noncrimp fabrics or as a stitchyarn for tailored fiber placement. It liquefies at 120°C/49°F and during cure dissolves into the host matrix, which reportedly enhances the part’s mechanical properties.
Specialty textile manufacturer Fabric Development Inc. (Quakertown, Pa.) revealed its purchase of TCR Composites (Ogden, Utah), a molder and maker of aerospace prepregs.
Literally the biggest thing at the show was a carbon fiber bridge manufactured by FiberCore Europe (Rotterdam, The Netherlands) and destined in early May for the Dutch town of Dronton. This 24.5m long by 5m wide (80.4 ft by 16.4 ft) structure weighs 12 metric tonnes (26,455 lb) features sandwich construction, with a large, corrugated honeycomb core between composites skins that consumed 3 metric tonnes (6,614 lb) of commercial grade Panex 35 carbon fiber from Zoltek Inc. (St Louis. Mo.). Fiber sizing and vinyl ester resin for the bridge project were provided by DSM Composite Resins AG (Schaffhausen, Switzerland). When load tested with 75 metric tonnes (nearly 164,400 lb) of weight, the bridge showed deflection of only 64 mm (2.52 inches). FiberCore claims the cost of the carbon fiber bridge is competitive with concrete at nine times less weight.
