Polystrand Develops Lightweight, Balanced Tri-Ply Reinforcement

9th April 2007 0 comments

Polystrand has developed a lightweight and balanced polypropylene impregnated reinforcement tape with fibres arranged in three layers with a 0°/90°/0º orientation. The continuous 25” wide tape provides 70 percent high-performance glass fibres by weight, made using a proprietary process that impregnates continuous fibre with a polypropylene thermoplastic resin. The reinforcement weighs only 29.4 ounces per square yard, a 20 percent reduction in weight compared to a three-layer product made with standard tapes. “Tri-Ply reinforcement is essentially a cross-ply sandwich with core fibres at 90 degrees between two layers of fibre at zero,” said Ed Pilpel, president of Polystrand. “With its low areal density, the tape gives engineers a great way to add strength, impact resistance and stiffness with minimal weight,” he continued. “The tape provides a clean and easy way to reinforce a variety of materials and it is ideal for aerospace, automotive and transportation applications where both strength and weight are critically important.” Pilpel said development of the new Tri-Ply reinforcement product began with a series of process improvements that enabled Polystrand to reduce the weight of its tapes. A singly ply of standard unidirectional material weighs 12.2 oz. while the new lightweight material is about 20 percent less at 9.8 oz. per square yard. The lightweight material is also available in an X-ply™ reinforcement product that weighs 19.6 oz. compared to 24.4 oz. for standard material. “The more experience we get the better the products become,” explained Pilpel. “Our product quality has always been the best in the industry and we continue to see it develop and improve as our technical people work with the process. The improvement can be seen in a variety of attributes including fiber alignment, homogeneity, surface finish and laminate integrity. “Last year we started production with a 25” wide machine that is twice the size of the industry standard,” he continued. “The new line incorporates all that we have learned in the past few years and makes a very efficient product with high surface quality. It’s the result of many years of experience and a lot of know-how in composites applied to a new continuous thermoplastic reinforcement.” Pilpel said triple-layer Tri-Ply reinforcement tape was developed to provide a “balanced” reinforcement that will lie flat during processing. “The key here is having unidirectional material on both sides of the middle cross or 90° layer.” While the structure of the reinforcement is balanced and flat, its strength is greater in the 0º or “uni” direction, adds Pilpel. “With two-thirds of the reinforcement being zero degree unidirectional, the product provides more strength in that direction,” he explains. “That’s perfect for applications that don’t need a bi-ply with equal strength in both directions.” Samples of lightweight and Tri-Ply reinforcement material will be shown next week in Paris at JEC Composites 2007, where Polystrand is exhibiting again this year. The company will be in the U.S. Pavilion at stand L 08 J.

9th April 2007 0 comments

Reinforced Telene has been developed by Rimtec, the parent company of Telene, and willl be on show at the JEC Exhibition. The new grade is currently being used and qualified in various truck applications and in the construction market in Japan. “Reinforced Telene can be used for large-sized parts in a variety of applications, where higher modulus or a lower coefficient of thermal expansion is required. Reinforced Telene widens the performance range of Telene grades and will provide technical answers to the current demands of designers & engineers.”” according to Alexander Daemen, President of Telene. Reinforced Telene has already found its first commercial application in Europe enabling an innovative new concept for the construction of swimming pools. In fact the engineers of Telene. combined two of Rimtec’s breakthrough developments for the design of this new generation modular swimming pool – the simultaneous use of the In-Mold-Coating process, an environment-friendly paint process, and the use of reinforced Telene. The panels of the swimming pool feature resistance to shocks, dimensional stability to temperature and anti-corrosion performance. This project, supported by ANVAR was developed in less than one year by Telene S.A.S and Terinjec with the support of the CRITT Provence Alpes Côte d’Azur. This development of reinforced Telene has already led to the submission of 17 patent applications and sets up the first of a series of made-to-measure formulations making it possible to explore new possibilities. Telene will be on stand L52 (Hall 1) at JEC Composites Show 2007

Integran to Launch Nanometal/Composite Hybrid Technology

9th April 2007 0 comments

Integran Technologies is introducing its Nanometal/Composite Hybrid technology to the composites industry at this year’s JEC Composites show in Paris, France (April 3-5, 2007). Nanometals have crystalline grain sizes 1000 times smaller, and strength and hardness 3-5 times greater than conventional metals. Through Integran’s proprietary process, these materials are produced as foils or applied as coatings, and are now being combined with carbon fibre reinforced polymer (CFRP) composites to provide additional hardness, durability and other functionality. In aerospace, a low thermal expansion coating (NanovarTM) has been developed to give lightweight composite tools a hard durable surface, allowing them to function like production metal (Invar) molds. In motor-sports, improving the durability of composite fascia’s and winglets against stone chipping is being explored. In sporting goods, a new hybrid golf shaft design was recently announced using the nanometal to improve torsional stiffness and resiliency, improving both shot distance and accuracy. “CFRP is an amazing engineering material, but with the addition of Nanometal coatings, engineers will be able to design lightweight products with previously uncharted durability and mechanical integrity,” says Andrew Wang, VP of Product Development at Integran Technologies. For more information on nanometals, visit Integran, at the Canadian Pavilion of this year’s JEC Composites show

Woven Pre-forms with Fillets Developed

9th April 2007 0 comments

Biteam has developed woven T and Pi cross-section beams with fillets, which will be exhibited at the JEC Composites show. Direct weaving of profiled pre-forms with fillets strengthens the joints and thereby improves the load-bearing capability of a composite material for structural applications. Profiled pre-forms having slender walls together with fillets at their intersections offer significant increase in performance and open up new application areas. Weaving profiles with fillets allows users to expand a given cross-sectional profile family to make available different types of that profile to choose from. For example, the pi cross-section profile can be woven with the fillets at either outer or inner or at all corners and thereby the most advantageous solution for a given application could be selected. Producing fillets in pre-forms directly during weaving also eliminates the time and effort associated with reinforcing the joints with stitches, pins or rods. Biteam will exhibit the novel filleted T and Pi profile pre-forms at JEC Show 2007, Stand K-64.

Roctool Begins Plastic Injection Adaptation of its Cage System

9th April 2007 0 comments

RocTool has specialized in rapid transformation of composites by electromagnetic induction and is now adapting this technology for plastic injection. Alex Guichard, the CEO of RocTool said that “this is a key stage in RocTool’s development. Our collaboration with the Tier 1 Visteon Group has allowed us to validate the feasibility and to identify the advantages of using this technology. “ In the automobile industry, the thickness of the part has not always been chosen by the mechanical function, but more often by the constraints of moulding. The injection by induction can be applied to thin or overmoulded parts, any type of cosmetic part and materials with strong viscosity, like elastomers. The current plastic injection procedure requires very high speed and pressure: As the preheated material is on a cold mould it solidifies, therefore needing a considerable pressure to fill the mould. The material is then stressed and shrinkage lines can appear on the surface, which explains the difficulty to obtain flat parts. RocTool proposes an alternative, by means of, rapidly heating (5 to 10 seconds) the surface of the tool by electromagnetic induction at a temperature close to that of the injected plastic, therefore the rheology conditions are ideal. The resin and the tool are at the same temperature and the flow is achieved without any effort. Alex Guichard specifies, “The development of our technology and its industrialization are in progress and should be available within 12 -24 months. We are developing two tools equipped with the technology and a demonstration will be installed in France by the end of 2007.” RocTool initially proposes licences of development to resins providers and transformers of parts eager to test the technology for their applications, and secondly the licenses of its patents, and the know how to use this process in production. RocTool will be at Booth L16 (Hall1) during the JEC Composites Show 2007

World's Largest Carbon Composite Bridge Span at JEC-Fair in Paris

9th April 2007 0 comments

With the largest carbon composite bridge span in the world, The Netherlands offers a revolutionary first at the prestigious JEC-fair in Paris. Never before has a complete bridge, including hand railings and wear surface, been transported in one piece on a truck to Paris. The journey from Rotterdam to Paris is taking three days via the Ardennes, the city of Reims, and during the night through the city centre of Paris. The average transportation speed during the trip is about 12 km per hour. The carbon composite bridge is 24.5 meters long and 5 meters wide and weighs only 12 metric tonnes. This makes the bridge about 30 times lighter than a comparable concrete bridge. The bridge has been designed and produced by FiberCore Europe of Rotterdam for the Dutch municipality of Dronten, with Haasnoot Bruggen as principal. The presentation of the bridge at the JEC-fair has been facilitated by DSM Resins, the supplier of the resin used to build the bridge. By launching the bridge in Paris, FiberCore Europe and DSM show that carbon composites are making a breakthrough in the building industry. The material is lightweight, stronger than steel and has a virtually indefinite lifespan. Furthermore, building with composites is an effective answer to global heating. Concrete and steel are quite polluting and thereby significantly contribute to this environmental problem. Bridges made of composites do not have these drawbacks and can even yield CO2-credits. With its free span of 24.5m, the bridge illustrates that composites can be produced and used in any conceivable shape. Because the bridge can be produced in series, it can be cost competitive with traditional materials like steel and concrete. Early May of this year, the bridge will be installed within an hour en opened by a.o. the mayor of Dronten. Close to the bridge, an information centre will be opened simultaneously, which will focus on the unique properties of composite materials as a building material.
