In order to reduce weight and improve fuel economy, automotive manufacturers are increasingly replacing metal parts with plastic parts that are reinforced with long glass fibers. The orientation of the glass fibers is critical to the overall performance, shape, and dimensions of the plastic parts. Thus, simulation is an invaluable tool in allowing designers to optimize their designs to maximize the benefits of using long glass fibers. Autodesk developed the industry’s first capability to predict the orientation of long fibers in collaboration with Pacific Northwest National Laboratory and the US Department of Energy on the prestigious FreedomCAR program. Autodesk® Moldflow® 2012 software helps to more accurately predict the orientation of short and long glass fibers, which are critical to the overall performance, shape, strength, and weight of plastic parts. Accurate fiber orientations help improve the prediction of process-induced mechanical properties and subsequent shrinkage and warpage predictions. Perform amazing simulations with Autodesk® Moldflow® 2012 software.

www.eurocarnews.com – Audi AG – Fiber-reinforced plastics (FRP) are a particularly intriguing group of materials, particularly the carbon fiber-reinforced plastics (CFRP). Audi already offers a number of CFRP components for the interior and the body, primarily in the R8 model family. These range all the way up to load-bearing structural elements such as the side walls and the cover for the top compartment in the R8 Spyder. In future models, Audi plans to use CFRP components manufactured using the much more efficient RTM (resin transfer molding) process in the vehicle structure. With RTM, the dried fiber fabric is first draped (formed) before being placed in a closed, heated die and injected with synthetic resin at high pressure. This ensures that the fabric is thoroughly saturated and cured under pressure and temperature. The experts at Production Technology Development have developed specialized expertise in both draping and injection, enabling them to optimize the production process in advance. The new CFRP parts will reinforce steel or aluminum components or will serve as independent components in the structure. Carbon fiber-reinforced plastic is not only around 60 percent lighter than steel, it is a designer material that allows the mechanical designers to freely define many component properties. CFRP components perform best when they are designed to absorb forces coming from a single direction. The individual layers of fiber fabric placed over top of one another in …

Just in! New for June 2010! The Kryptonite line of ultra strong, virtually UNBREAKABLE Flair Bottles. This new line of flair bottles uses an injection molding process rather than blow molding therefore guaranteeing a PERFECTLY FORMED flair bottle every time. Perfectly balanced. Perfectly weighted. Perfectly solid. And a perfect feel and grip. These Kryptonite bottles are as tough as they get, and are made from our trade secret “Kryptonite” material! Choose from several different styles. We offer the traditional solid white 750 ml bottle, as well as clear and colored transparent bottles. And to bring a little more flair to the show we are offering this bottle in a brilliant neon green (glows under a black light) … a powerful kryptonite effect! Lighted Flair Bottle is Below. Priced right! Stay tuned for deocated ones.

Autodesk® Moldflow® Insight Radium Technology Preview software ( download at www.autodesk.com ) calculates the orientation of long fibers in plastic materials. Customers are now able to accurately predict how plastic materials reinforced with long glass fibers will behave during the injection molding process as well as the effect of the fiber orientation on the product’s mechanical behavior and warpage.

The Project Scandium Technology Preview for Autodesk Moldflow Insight allows you to try out four new solver technologies that get you closer to simulating the injection molding process than ever before. Learn more on labs.autodesk.com
