The consensus on the show floor at the 2009 edition of the JEC Composites Show was that although attendance this year did not equal 2008 levels, the turnout was greater than expected. Postshow statistics released by show organizers tended to support that contention. By JEC’s count, 1,065 exhibitors (75 percent from outside France) and 25,500 visitors from France (35 percent) and 95 other countries. Some observers credited the attendance levels at the show, held March 24-26 at the Paris Expo in Porte de Versailles, Paris, France, to the fact that JEC highlighted neighboring Germany as its featured guest country and selected an “Automation” theme, which attracted new European exhibitors that offer automated solutions. According to JEC, visitor traffic was actually up significantly this year in four market sectors: wind energy, 35 percent; aerospace, 28 percent; building and construction, 18 percent; and — very surprising, given plummeting new car sales — automotive, 16 percent. JEC says the unexpected statistics owe much to an increase in traffic from composite component end-users.

At a show press conference, JEC Group president/CEO Frédérique Mutel added an upbeat note to the gathering with a presentation of JEC’s latest composite market study figures, which puts the worldwide market value of the composites industry at €62 billion ($82.4 billion USD) with a total volume of 8.6 million tonnes (18.9 billion lb). Despite the recessionary climate, her take is that the compound annual growth rate through 2013 will be at 4 percent, with the largest growth occurring in Asia (see photo, p. XX). The growth rate should be faster than the gross domestic product (GDP) growth rate, says JEC, with building and construction and wind energy the fastest-growing market segments.

In other show-related news, SAMPE Europe, JEC and the organizers of the AUTOMATICA conference signed a joint agreement to collaborate at the next AUTOMATICA gathering in 2010. A dedicated “Composites Pavilion” organized by JEC Composites and a two-day trade conference organized by SAMPE Europe will help advance automation methods in the composites industry, say the three groups. The conference portion of the collaboration, to be entitled "Advanced Composites for Automatization,” is being organized by Dr. Klaus Drechsler of the Technical University of Munich.

On the Paris show floor, HPC staffers found the following notable news and developments.





Tooling & out-of-autoclave prepregs

Advanced Composites Group Ltd.’s (ACG, Heanor, Derbyshire, U.K.) large and busy stand showcased several of the group’s accomplishments, including commercialization of trademarked DForm deformable composite system (DCS) prepreg material for tooling and out-of-autoclave prepregs for a variety of industries. The company announced a three-year supply agreement with Southern Spars (Auckland, New Zealand) under which ACG will supply its MTM prepreg for Southern’s carbon fiber spars and rigging. Also announced was the company’s attainment of ISO TS 16949 market accreditation from Lloyd’s Register for automotive industry applications.

Multilayer films also are available. The company’s reactive hybrid adhesives, based on silanes and epoxy resins, address requirements in load-bearing vehicle, ship and container fabrication processes.





Crush-simulation software for composites

Dassault Systèmes (Paris, France and Providence, R.I.) emphasized its recently released CZone for Abaqus, from the DS SIMULIA brand. A new add-on product for Abaqus finite element analysis (FEA) software, the program simulates crushing of composite materials, enabling engineers to accelerate the design and evaluation of energy-absorbing composite components and assemblies. Based on technology from Engenuity Ltd. (West Sussex, U.K.), the new product provides the ability to study the crashworthiness of composite structures in automobiles, helicopters, aircraft, railcars and other vehicles to protect occupants and cargo from shock or injury during severe impact.





Structural health monitoring

Fraunhofer-Gesellschaft (Darmstadt, Germany) focused its presence at the show on structural health monitoring systems in aircraft wings. In its stand it had an aircraft wing with 42 sensors integrated in or applied to the structure to monitor loads, impacts and damage. By processing and interpreting all of the sensors’ signals, Fraunfofer researchers intend to correlate data with experimental tests, thus more accurately assessing the structes condition and health.





Prepregs for the automotive market

Hexcel (Dublin, Calif. and Duxford, U.K.) touted materials tailored for the automotive industry: HexPly M49 prepreg for car body parts and interiors; and HexPly XF3, a surfacing film that reportedly provides a ready-to-paint surface finish with minimum preparation and is compatible with most epoxy prepregs and adaptable to a wide range of cure cycles, from 100°C to 140°C (212°F to 284°F).

On display in the stand was a bonnet (hood) for the Lamborghini Gallardo, manufactured by ACE GmbH (Immenstad, Germany) using resin transfer molding with HexForce NC2 multiaxial carbon fabric, said to permit full resin infusion and provide a very smooth surface that reduces the print-through effect of the carbon. The Gallardo gear selector is manufactured with HexMC carbon fiber/epoxy that facilitates layup of parts with complex shapes.

Also of interest to automotive customers is the HexForce PrimeTex range of fabrics that have been processed for a smooth, closed weave and uniform cosmetic appearance. The fiber tows are spread via patented processes in both the warp and weft for unique aesthetic appeal. Trademarked PrimeTex fabrics are being used by automaker BMW on the inner and outer skins of the carbon/epoxy roof of the current M3 and M6 models.



Resins for fuel cells & aircraft interiors

Huntsman Advanced Materials (The Woodlands, Texas) received a JEC Innovation award in the “Raw Materials” category for two new resin systems based on benzoxazine and bismaleimide chemistries. The new resins allowed Huntsman’s award partners GrafTech International (Parma, Ohio) and Ballard Power Systems (Burnaby, British Columbia, Canada) to produce next-generation bipolar plates for fuel cell applications. The system is based on a phenolic-like backbone and operates at continuous temperature of 248°F/120°C. For stationary and back-up power applications, Huntsman introduced a flame-resistant bismaleimide resin, designed for use in fuel cells that operate at temperatures of up to 356°F/180°C in concentrated phosphoric acid. This material can be used in conventional prepregging processes. Fuel cell materials should be commercially available later by early 2010.





Ultrasonic camera for real-time NDI

Imperium Inc. (Silver Spring, Md.), a provider of ultrasonic camera solutions for nondestructive inspection (NDI), reported that Hexcel Corp. (Stamford, Conn.) has selected Imperium's Acoustocam I-500 for use by its Dublin, Calif., research lab to support application engineering efforts related to composite material inspection and evaluation of its HexMC molding material and other composite materials. Alfonso Lopez, application engineer for Hexcel, said, "Imperium's Acoustocam I-500 provides a terrific solution for non-NDI certified engineers to easily and effectively evaluate our composite materials in real time. Our investigation of other NDI equipment indicates that they do not offer such unique value."





Autoclave with external gas-fired furnace

Italmatic (Lucca, Italy) exhibited its line of autoclaves for composites curing. Company manager Roberto Frediani described a recent, highly efficient installation for Stork Fokker AESP (Papendrecht, The Netherlands) that uses an external gas furnace to heat the process air, rather than a direct combustion, electric heating source within the vessel itself. Hot air is transferred from the furnace via a closed loop to the pressure vessel through a heat exchanger; a ventilator inside distributes the hot air throughout the vessel to evenly heat the parts. The hot exhaust from the vessel stays in the closed loop to preheat incoming air and reduce the amount of heat energy required by the furnace. The system is designed for high thermal efficiency (82 percent), low-temperature exhaust, low NOX and CO2 emissions and minimum maintenance. The concept reportedly saves Stork Fokker significant energy costs while providing enough heating capacity for curing high-temperature thermoplastic parts. The system will be protected by an international patent.





Nesting & NC-code software for cutting systems

JETCAM International (Monaco) announced a new suite of software applications at JEC, including JETCAM Expert, which provides a nesting engine and NC-code output for cutting systems used on composites. As part of this rollout, the company challenged visitors to provide CAD files of existing parts along with a DXF file of their of best attempt to nest those parts. JETCAM then provided a comparison, using its High Performance Nesting engine, which reportedly can provide material savings of 5 to 15 percent. The company also launched its Material Life Management (MLM) software, which stores and then provides users with real-time data about available materials, including material stock levels, material left on a roll, material location, expiration date, how long each material has been out of the freezer, and other data.

The water-based, nonhazardous, silicone-free, semipermanent external mold release agent is designed to form a high-gloss finish on molded parts. Designed for use on most mold substrates (e.g., composite, aluminum and steel), the product reportedly provides multiple releases, yet offers ease of application with superior wet polishing and minimal fouling of tooling during processing. Recommended for use with most thermoset resins, it can be wiped on or spray applied over a sealed mold to form a smooth, durable, glossy film with excellent adhesion to the interfacial coating. Odorless, nonhazardous, and nonflammable, the product contains no hazardous air pollutants (HAPs) or volatile organic compounds (VOCs).





Inductively heated molding system demonstrated

RocTool (Le Bourget du Lac, France and Atlanta, Ga.) periodically demonstrated its high-speed thermoplastic composite molding process, producing composite laptop computer covers on the company’s Cage System. The Cage System features an inductive heating system that heats only the thickness of the mold surface, providing for rapid ramp to molding temperature and fast cooldown cycling. A blank of material can be elevated from 50°C/122°F to 250°C/482°F in 70 seconds before forming, enabling users to achieve part production cycles of just over two minutes. Material for the covers was provided by Roctool partner Performance Materials Corp. (PMC, Camarillo, Calif.) and consists of unidirectional carbon fiber (12K and 24K) in a PET resin matrix. The covers, designed to compete with magnesium versions, have wall thickness of only 0.8 mm/0.03 inch, offer competitive cost and stiffness and emerge from the mold ready to paint. PMC is a licensee of the Roctool Cage System process and is working with laptop manufacturers on supply agreements.
