Metal replacement simplified

Ems-Grivory says that its long fibre reinforced polyamides (PAs) are suited for metal replacement, especially in automotive construction. These materials combine high stiffness and strength values with low weight. The company has expanded its long fibre product range with two new products.

The endless fibre tapes, delivered on spools, can be cut to length and then laid into the component mould (pictured here is the demonstration component developed in cooperation with the HSR Technical College, Rapperswil, Switzerland) (photos: Ems Chemie)

Ems-Grivory: Long fibres for sports and leisure

Ems-Grivory presented their range of long fibre reinforced polyamides (PA) and their properties. One application example was the Spectre touring ski boot made by the Italian company La Sportiva. Thanks to its materials and ingenious design, the ski boot weighs only 1,395g, which makes it the lightest four-buckle ski boot ever. Products from Ems-Grivory are used in the boot’s heel shell, where a long carbon fibre reinforced PA12 and a tough Grilamid PA12 are said to ensure a high level of stiffness and high notch impact strength. As a result of its long fibre reinforcement, the notch impact toughness is more than twice as high, tensile E-modulus is 60% higher and strength 70% higher than for short fibre reinforced PA12 grades, according to the company. Consequently, the ski boot is stiff and is at the same time protected against impacts. The materials can be welded together using two-component injection moulding methods.

PlastiComp develops next generation LFT-PA

PlastiComp has developed the next generation inlong fiber reinforced nylon composite pellets (LFT-PA composites).  The main features of these materials are the high flow characteristics and good surface finish they exhibit even with high fiber loadings and without a reduction in thermal or mechanical properties.

The company’s proprietary high flow formulas enable moulders to achieve cycle time reductions up to 25% along with injection pressure reductions of up to 40% in thin wall parts (less than 2.54mm/0.100”).  Flow lengths in thin wall parts can also be increased by as much as 30% (based on spiral flow data).  The reduced viscosity of these formulas gives improved design flexibility by allowing wall thickness reduction of up to 25% in some parts.  It also gives moulders the ability to mould complex and large shapes with high filler contents.  Reducing process temperature and pressure provides secondary benefits including longer mould life as well as reduced mould and moulding machine maintenance costs.

Integrated front-end module honoured

The first North American implementation of an integrated front-end module (FEM) system used on 1996 model year (MY) Ford Taurus and Mercury Sable sedans produced by Ford Motor was selected as the 2013 Hall of Fame winner by the Automotive Division of the Society of Plastics Engineers (SPE) for the group’s 43rd-annual Automotive Innovation Awards Competition. To be considered for a Hall of Fame award, an automotive-plastic component must have been in continuous service in some form for at least 15 years and preferably have been widely adopted within the automotive or ground-transportation industries.
