OCTOBER 2018 50 CompositesWorld Composite product and process development assistance The Composite Development Centre of Québec (CDCQ, Québec, ON, Canada) is featuring its services, designed to help businesses and organizations that are part of the composites value chain with applied research services, technical assistance and information activities, improving the quality and performance of their products. The center includes a multifunctional laboratory with equipment covering the majority of composites fabrication processes, and a material charac- terization and testing laboratory, accredited to ISO 17025. The CDCQ is a College Center for Technology Transfer (CCTT), recognized by the Québec government and affiliated to the College of Saint-Jerome. The center has developed a niche in green composites, including composites recycling (glass and carbon fibers), valorization and long-fiber ther- moplastics. Services include applied research; material, process and equipment selection; process development, optimization and start-up; troubleshooting; molding trials and prototyping; 3D printing (prototype molding); materials characterization; and training. Booth CC49. High-temperature, low-CTE tooling board Compotool (Monroe, WA, US; Auckland, New Zealand) is featuring its inorganic tooling board made from specialized formulated calcium silicate materials that reportedly exhibit favorable thermal and process characteristics. This tooling board is said to be thermally stable and able to withstand temperatures of more than 1,000°F with minimal thermal conductivity. The board has a theoretical coefficient of thermal expansion (CTE) of less than 3.3 x 10 -6 F -1 . The material's low thermal conductivity, says Compotool, reduces oven or autoclave cycle time while energy requirements are relatively low. The Compotool tooling boards are available in high-density (55 lb/ft 3 ) CT850, medium-density (47 lb/ft 3 ) CT750 and low-density (18 lb/ft 3 ) CT300. These densities are formulated to be easy and fast to machine to high accuracy. Cutting is similar to wood and the material is nonabrasive, resulting in minimal tool wear. The different densities can be used in combination to reduce overall cost and weight. Compotool also provides matching high- temperature adhesive and sealing systems that allows users the ability to build mold shapes that can be used for either a master model or for short run direct molds. Compotool tooling boards are compatible with resin systems that require high processing temperatures such as cyanate ester, benzoxazine, bismaliamide, polyamide and thermoplastic systems. Booth M43. Machine-independent programming, simulation, control software Machine control and software specialist CGTech (Irvine, CA, US) is demonstrating Composites 8.1, the latest version of its VERICUT Composite Programming (VCP) & VERICUT Composite Simulation (VCS). Composites 8.1 features a redefined graphical user interface (GUI), an enhanced suite of programming and analysis tools, and redefined methodology through the use of a new Laminate Manager. In addition to organizing files, the Laminate Manager brings clarity and visibility to the laminate as a whole. This laminate overview, says CGTech, has made several other new enhancements possible, like batch processing, laminate-wide analysis and intelligent ply generation. CGTech is also featuring its latest version of VERICUT 8.2, CNC machine simulation, verification and optimization software that enables users to eliminate the process of manually proving-out NC programs. VERICUT simulates all types of CNC machining, including drilling and trimming of composite parts, water jet cutting, riveting, robotics, mill/turn and parallel kinematics. Visitors to CGTech's booth will also get information on new projects that highlight the use of machine- independent, offline NC programming software for automated fiber placement (AFP) and automated tape laying (ATL) machines, such as the work being done at NASA's Langley Research Center using a 16-tow Electroimpact AFP machine. Booth BB28. Non-traditional machining process supports range of materials IKONICS Advanced Materials Solutions (Deluth, MN, US) is showcasing its Precision Abrasive Machining (PAM), a non-traditional machining process. PAM supports a range of materials such as carbon fiber, glass fiber, Kevlar, ceramic matrix composites (CMCs), silicon carbide, sapphire, glass, alumina, graphite and more. The process reportedly enables perforations in any shape and with clean edges, high-precision repeatability, fewer stresses or defects, complex curve capabilities and flexible and rapid design changes. No secondary machining services are needed. Suitable applications include engine liners, thrust reversers, blocker doors and other parts that require hundreds or thou- sands of perforations. PAM is said to provide a high degree of accuracy and repeatability within 50 microns, as well as fast turn-around and prototyping for design changes. Booth G90. SHOW PREVIEW
