CompositesWorld.com 41 » FIRE PROTECTION SYSTEMS Fabrics designed for fire protection in composites applications SAERTEX (Saerbeck, Germany) recently announced two new products in the area of fire protection for composites, SAERTEX LEO Coated Fabric and SAERcore LEO. SAERTEX LEO Coated Fabric meets the most stringent fire protection requirements for rail transportation, the marine sector and the construction industry. It complies with the strictest fire safety standards and railway applications HL3 according to EN 45545-2 (-3). It is suited for manufacturing simple or curved structural parts and is processed using the vacuum infusion technique. The product SAERcore LEO, also meets the HL3 fire protection requirements in accordance with the EN 45545-2 standard. It is suited for parts with complex shapes that are also subjected to low mechanical stresses. SAERcore LEO can be used within resin transfer molding (RTM) and light RTM. saertex.com » CARBON FIBER FILAMENT Carbon fiber filament for 3D printing composite prototypes, parts Royal DSM (Geleen, The Netherlands) recently launched its new carbon fiber-filled grade PA6/66 filament Novamid ID1030 CF10 for 3D printing. Despite the low carbon fiber loading of 10%, it reportedly produces functional prototyping and industrial parts with properties close to what is usually achievable only by injection molding, while matching the fast printing of unreinforced plastics. Novamid ID1030 CF10 3D is designed for printing structural parts that are said to be strong, stiff and tough with high tensile strength and modulus, high dimensional stability and free of warpage. These mechanical properties and smooth appearance reportedly make the carbon fiber filament well-suited for a range of applications that require robust performance at elevated temperatures. Possible applica- tions include parts for automotive, sports gear, manufacturing jigs and fixtures and medical braces and prosthetics. The material can be printed on standard desktop fused filament fabrication (FFF) machines with a hardened nozzle. Tests have shown that users can run their printers at the same speeds as with unrein- forced plastics, while achieving improved strength and toughness. The material has been tested on several open FFF platforms, including on GermanRepRap and the Ultimaker S5. dsm.com » FOAM CORE MATERIALS Polyethersulfone particle foam BASF (Ludwigshafen, Germany) recently announced it has developed prototypes of what it says is the world's first particle foam based on polyethersulfone (PESU). The foam is characterized by high-temper- ature resistance, inherent flame retardancy and light weight coupled with good stiffness and strength. According to BASF, Ultrason E is an amorphous thermoplastic with a high glass transition temperature of 225°C and remains dimensionally stable up to this temperature. Foams made of Ultrason E are approved for use in aircraft. The material, with its high limiting oxygen index of 38 (according to ASTM D 2863), meets the requirements for commercial aircraft with regard to combustibility, low heat release and low smoke density without the addition of flame retardants. The expandable PESU granulate is pre-foamed into beads with densities of 40-120 g/L and can be processed into molded parts with complex 3D geometries. Despite its low density, the PESU particle foam is said to enable stiff and strong components with good dimensional stability at high temperatures. According to BASF, it is well- suited for complex-shaped components in cars, airplanes and trains, which must be able to withstand high operating tempera- tures and meet stringent flame-retardant requirements. basf.us/composites YOUR PARTNER IN...
