Anticipating an increased number of exhibitors and visitor traffic for 2006, the 2006 JEC Composites Show, held from March 28-30, expanded its footprint again this year at the Paris Expo in Porte de Versailles, Paris, France. Exhibit space was increased by 1,000m2 (10,764 ft2) to accommodate wider aisles and additional stands. JEC reports that there was an increase in the number of exhibiting composites processors from Northern Europe, Germany, Great Britain and France. Composites manufacturers, in fact, accounted for 30 percent of the total number, while suppliers of raw materials were there in equal numbers. The remaining 40 percent comprised equipment manufacturers, distributors, service providers, associations, institutes and universities.

Suppliers in aerospace/defense arenas and other industries in which advanced composites are competing for traditional metals markets told HPC that business continues strong. That strength was evidenced on the show floor. HPC staffers discovered that visitors had an abundance of recently introduced products and services from which to choose, from resins, fibers and prepregs to dust extraction and vibration damping technologies. The following is a representative sampling of what was available:

Advanced Composites Group Ltd. (ACG, Heanor, Derbyshire, U.K.) spotlighted its £7 million/$13 million (USD) expansion to its Heanor facility. The 30,000 ft2 (2,787m2) Technology Centre will house the company's resin formulation, testing, process engineering and other R&D functions. In addition, the package includes major investments in new resin mixing and prepregging equipment. ACG also announced agreements with Advanced Composite Technology Ltd. (Auckland, New Zealand) and Duly Corp. (Seoul, Korea) to represent ACG in their respective regions. advanced-composites.gocomp.biz/28

Aerovac Systems (Keighley, West Yorkshire, U.K.) and U.S. distributor Richmond Aircraft Products Inc.

T90, available in a range of densities, allows fabricators to combine different core densities in one sandwich structure to optimize properties. Also new: BALTEK Gold, is a balsa wood core treated to prevent decay. Currently being tested in Hawaii, the Gold product comes with an extended performance warranty. alcanairex.gocomp.biz/10

Assembly Guidance Systems (Chelmsford, Mass.) introduced its Universal Laserguide, a wireless and targetless multitasking laser system. The fully portable unit is radio frequency (RF) controlled, and therefore needs no umbilical to attach it to other equipment. It employs a CDRH Class II laser, reportedly the safest category of laser for projecting patterns. The system projects laser patterns on unreferenced surfaces and also can preform laser-based metrology. According to the company, the system can be set up for pattern projection in less than three minutes. assemblyguide.gocomp.biz/10

Axel (Woodside, N.Y.) introduced five new mold release products, including XTEND W-7837D, a water-based, semipermanent that yields a consistent matte finish on molded parts. Designed to release many parts without requiring reapplication, the product ensures part-to-part finish consistency, an important requirement in wind blade production. The aqueous emulsion of proprietary resins and reactive surface modifiers can be sprayed or wiped on at either ambient or elevated temperatures and reportedly is suitable for use on FRP, aluminum and steel mold surfaces to produce composite parts with polyester, vinyl ester or epoxy matrices processed at temperatures up to 220°C/425°F. axel.gocomp.biz/23

3-D weaving pioneer Biteam (Bromma, Sweden) promoted its capability to make solid integrated beam preforms of woven carbon fiber for supporting aero engine guide vanes and other engine components. Beams incorporate a tapered section at one side of a vertical section to provide increased base area while simultaneously supporting and strengthening the beam's vertical section. This construction reportedly reduces the use of oversized beams. The preform can be woven straight or with a specified radius of curvature. biteam.gocomp.biz/4

Bodycote Materials Engineering (Lancaster, U.K.) announced its acquisition of the warrington Group of companies, located at three sites in the U.K. and additional locations in Belgium, France, Italy, Hong Kong, United Arab Emirates and Australia. The acquired firms perform consulting and testing services for a number of international standards, as well as architectural product testing, inspection of fire protection systems and certification at the local and EU (CE) levels in Europe. The move gives Bodycote access to a sector of testing activity that complements similar existing activities in its North American operations. bodycote-mt.gocomp.biz/8

Bryte Technologies (Morgan Hill, Calif.) highlighted two new toughened epoxy resin systems: TC250, a 250°F-/ 121°C-cure system for either vacuum bag/oven cure or autoclave, offers the ability to achieve postcure Tg values of up to 350°F/150°C, making it a suitable system for general and civil aviation. The resin can be cured in 30 minutes. TC350, a 350°F-/177°C-cure system for critical primary and secondary aerospace structures, is autoclave-only and offers a compression-after-impact strength of 35 ksi/241 MPa after a 1,500 inch/lb impact. Both are available in uni tapes and woven and nonwoven prepregs. brytetech.gocomp.biz/6

CompoTech (Cowes, Isle of Wight, U.K.) introduced a manufacturing process that uses ultrahigh-modulus pitch carbon fiber to manufacture structural tubes, which can be used in almost any type of high-speed industrial machinery (e.g., milling machines, robots and printers). The pitch-based fiber offers higher bending and torsion stiffness than PAN-based fiber and can be cost-effective when used in volume, says the company. The manufacturing process can produce custom shapes and sizes, with high repeatability and increased stiffness — more than 400 GPa, or twice as stiff as steel at one quarter the weight. compotech.gocomp.biz/1

Cytec Engineered Materials Inc. (Tempe, Ariz.) highlighted a number of innovations, including a new bismaleimide (BMI)-based tooling material, DuraTool 450, designed to provide a durable but less expensive alternative to Invar and epoxy tooling; new resin infusion systems and new prepregs; and an expansion of Surface Master production.

Quickstep Technologies Pty. Ltd. (Canning Vale, Western Australia) showcased the company's proprietary mold technology in which a mold face is semiflexible and is supported by a heat transfer fluid. The system enables application of both heat and pressure, eliminating autoclave processing. In addition to centers of excellence at the the University of Manchester's Northwest Composites Centre and at Deakin University (Geelong, Victoria, Australia), the company signed a letter of intent with the National Composites Center (NCC, Kettering, Ohio) for a collaboration that will include the acquisition by NCC of a QS20 composites production machine for a third center of excellence. quickstep.gocomp.biz/5

Tajima GmbH (Winterlingen-Benzingen, Germany), at the JEC for the first time, demonstrated a new preforming process that combines fiber placement technology with stitching. The machine lays down a single dry carbon tow (or other fiber) onto a flat table, using a computer-controlled head. The head then stitches the tows with any type of thread to hold the preform shape together on an underlayment of paper, film, foil or other material. Multiple plies are possible in any orientation to form a multiaxial preform of any shape with virtually no waste, since the preform shape can be reproduced exactly with the CNC-controlled head. tajima.gocomp.biz/2

Thermwood (Dale, Ind.) had its 5-axis CNC Router for 3-D machining applications on display at the Halbronn Composites stand. The router comes in seven models with processing envelopes ranging from 5 ft by 5 ft to 5 ft by 12 ft (1.5m by 1.5m to 1.5m by 3.7m), and four others with fixed tables, from 5 ft by 10 ft to 10 ft by 20 ft (3m by 3m to 3m by 6.1m). Each features a Thermwood-built CNC controller, which eliminates stoppages and slow-downs associated with commercial controllers. The machines also come with a spring-loaded impact-resistant cutting head, which avoids most calibration readjustments associated with head-fixture collisions. thermwood.gocomp.biz/2
