Lehvoss North America has introduced LUVOCOM SCF, a new generation of high strength, impact resistant high-performance compounds for structural metal replacement.
Based on polymers such as PA 6, PA 66, PA 46, and PPA, and reinforced with carbon fibres, the LUVOCOM SCF product range aims to deliver outstanding performance compared to traditional carbon fibre compounds.
According John Vermeulen, Business Development Manager at Lehvoss North America, “The LUVOCOM SCF product line was developed in response to market demand for lighter and stronger materials offering improved performance and overall cost reductions. Increases in strength and stiffness, however, often compromise toughness. Our new carbon fibre technology pushes the performance boundaries of traditional injection moulding engineering compounds even higher, thereby offering new design possibilities for lighter, stronger components.”
According to Lehvoss, when compared to traditional carbon fibre reinforced polymers, LUVOCOM SCF has higher tensile strength (+50%) and stiffness (+15%) as well as improved impact resistance (+90%). When compared to glass and traditional carbon fibre compounds, LUVOCOM SCF has outstanding mechanical properties. “Because of its lower specific gravity, it is lighter than metal or glass reinforced polymers,” said Vermeulen. “Plus, it has good tribological properties, is electrically conductive, and has low coefficient of thermal expansion (CTE).”
LUVOCOM SCF is processable on standard injection moulding machines. “It is important to maintain the excellent product properties by a well-adjusted molding process,” said Vermeulen. “This means sufficient pressures, optimized injection speeds, and well-dimensioned gates to avoid excessive shear.”
Lehvoss say LUVOCOM SCF high performance compounds offer precisely tuned material properties for a wide range of engineered components in automotive, oil and gas, and industrial markets. Specific applications include dynamic parts in pumps and compressors such as vanes, impellers, thrust washers, and seals. “These new compounds offer reductions in weight and associated energy savings,” said Vermeulen.

ZSK will hold its bi-annual technology showcase on 21-22 September 2018 at its Krefeld, Germany, headquarters. The Embroidery Technology Show assembles more than 25 exhibitors from around the world to discuss emerging trends in the embroidery manufacturing industry and demonstrate the latest products produced using techniques such as tailored fibre placement (TFP) or smart textiles.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
Fibrelite reports that since the start of its partnership with Trenwa more than 100 precast trench systems integrating Fibrelite composite covers have been sold for use in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.
