On the CWE show floor
HPC invited CompositesWorld Expo exhibitors to preview their products, services and planned visitor-oriented activities. The following responded with word about what to expect.
Oxidation oven systemsC. A. Litzler Co. Inc. (Cleveland, Ohio) will present new oxidation oven systems that use the company’s exclusive cross-flow oven technology, with patented End-Seal System. The alternating cross-flow design provides uniform airflow across the entire tow band up to 3m/9.8 ft wide. Litzler ovens have successfully processed tow ranging from 1K to 350K. The End-Seals on the inlets and outlets of the oxidation oven prevent cold air from infiltrating the oven and, therefore, optimize internal airflow and ensure temperature uniformity while minimizing hydrogen cyanide (HCN) levels. Uniform temperatures and airflow produce higher quality products at higher speeds than those that can be produced with competing designs. Litzler has more than 50 oxidation ovens installed in the U.S., Taiwan, China and Europe.

CNC programming software for fiber placementSoftware developer CGTech’s (Irvine, Calif.) product marketing manager Bill Hasenjaeger will be a speaker in the CWE Conference Advanced Track on Monday, Sept. 28: Noting that most users of computer numerical control (CNC) automated fiber placement (AFP) machinery use the offline numerical control (NC) programming software delivered with their machines — forcing them to use multiple software applications for multiple brands of machines — Hasenjaeger will discuss the benefits of machine-independent offline NC programming software. During the Expo, CGTech will demonstrate VERICUT Composite Programming (VCP) software, which reads CAD surfaces and ply boundary information and adds material to fill the plies, according to user-specified manufacturing standards and requirements. Layup paths are linked to form specific layup sequences and are output as NC programs for the automated layup machine. CGTech also will exhibit VERICUT 7.0, the latest version of VERICUT CNC machine simulation and optimization software. Its enhancements reduce the time required for manufacturing engineers to develop, analyze, inspect and document the CNC programming and machining process. Instead of new features or add-on modules, CGTech has focused on diligent code optimization and customer-driven enhancements.

Inductively heated mandrelAcrolab Ltd. (Windsor, Ontario, Canada) is introducing trademarked Isomandrel, which permits curing of filament-wound pipe and tube sections without the need for curing ovens. The system heats the mandrel uniformly, while rotating, using induction heating coupled with an internal process (within the mandrel) that enhances its thermal conductivity and thermal reactivity. Acrolab worked with McClean Anderson (Schofield, Wis.) and Ameritherm (Scottsville, N.Y.) to construct an Isomandrel curing station, which was used to cure several 1,219-mm/48-inch long pipe sections wound with glass and carbon fiber epoxy prepregs. The work was done at TCR Composites (Ogden, Utah) using a 76.2-mm/3-inch OD Isomandrel. At the end of the winding cycle, the sections were successfully cured on the Isomandrel, using an EKOHEAT induction power supply and coil assembly while the Isomandrel and winding were still mounted and rotating at a reduced 10 rpm on the Super Hornet Winder. Ameritherm and McClean Anderson are developing an integrated software/hardware station to provide the controlled power and recipe requirements for Isomandrel technology.

Nickel vapor deposition toolingWeber Manufacturing Technologies Inc. (Midland, Ontario, Canada) will spotlight its nickel vapor deposition (NVD) mold technology for out-of-autoclave processing. Weber reports that in comparison to steel or Invar tools, its NVD customers are seeing rapid heating and cooling rates as a result of nickel’s thermal conductivity, conformal heating and reduced tool mass. By way of illustration, Weber representatives will discuss with visitors a tool the company recently constructed: a 10-mm/0.393-inch thick, solid, pure nickel shell mounted on an egg-crate steel weldment. The nickel shell itself was produced in 40 hours by depositing nickel onto a CNC-machined, metallic mandrel, using Weber’s NVD process. Heating tubes were integrated into the back of the NVD shell. Then the mold surface was hand-polished to an automotive Class A finish. After inspection, all tooling is tested at Weber prior to shipment to the molder.

Laser projection systemLAP Laser’s (Cincinnati, Ohio) exhibit will focus on its CAD-Pro 3-D laser projector, a “virtual templating system” that projects, from CAD data, the outlines of contoured prepregs, reinforcements, preassembled components, fasteners and other objects to within 0.76 mm/0.030 inch. The unit mounts above the layup area and projects directly onto the ply layup tool or other contoured surface. The projection is based on CAD data. Design updates can be implemented on the fly. The system can project three colors (green, red, and yellow) simultaneously, making it possible to highlight areas that require special treatment or attention signal warnings, and to indicate the direction of fibers on a contour. Outlines on large parts (largest dimension up to 30.5m/100 ft) are imaged by using several projectors while data is automatically allocated to the corresponding projector.
