...ases and the associated frequency becomes smaller. The reason for this lies in the fact that the geometrical stiffness of the part decreases as the angle increases. A comparison with the results of the conditioned polyamide (grade: Durethan B 30 S, manufacturer: Lanxess AG, Leverkusen/Germany) shows that the same effect can be observed with a reduction of the mechanical stiffness. The first guidelines for acoustic design can be derived from these experimental results. Stiffer materials or change...

... is a range of extrusion grades with 20% lower processing temperatures than conventional PA6 grades, resulting in up to 40% higher output rates. For structural components and underhood applications, Lanxess is supplying a new 60% glass-fibre-filled Durethan PA6 grade with a tensile modulus of 20000MPa at room temperature and a value of 6700MPa, even at 170°C. In hybrid technology, particularly, use of the new material leads to components with higher rigidity and flexural/torsional strength. In ...

...ces to firmly bond a modifier chain with many functional (polar) groups (Fig.2). The experiments described in the following were performed on polycarbonate (grade: Makrolon 2803; manufacturer: Bayer MaterialScience AG) and on polyamide (grade: Durethan B 40 E; manufacturer: Lanxess Deutschland GmbH). Appropriate modifiers were selected by the Institute for Polymer Research in Dresden. Polyvinyl alcohol (PVOH) and polyethylene imide (PEI) were found to be suitable modifiers for polycarbonate, whi...

...s well as fibre and matrix fragments (Fig. 2). The EP matrix was made to decompose by thermal treatment in air or nitrogen, this treatment allowing the carbon fibres to be recovered without damage. The matrix systems consisted of polyamide 6 (grade: Durethan B 29; manufacturer: Bayer AG, Leverkusen) and a polypropylene (grade: Novolen 1100 H; manufacturer: BASF AG, Ludwigshafen). For comparison purposes, conventional carbon fibres and commercially available chopped low-alkali textile glass were ...

Kunststoffe international, 2005-11-21, Simulation right through to Failure
... AG was applied to the so-called "Erlangen Beam" in the first instance. This is a hybrid structure made of a U-shaped steel-sheet profile that has lateral flanges and injected-in ribs in polyamide 6 with a 30 % glass fibre component (grade: Durethan BKV 30; manufacturer: Bayer) - Fig. 2. The relatively high glass fibre content means that no necking occurs here, and the tensile strain at break is lowered. This material involves the demanding task of converting stress-strain curves for dif...

...iate input data must first be provided. In the first step, a geometric model is created as a CAD file and meshed. The case presented here involves two plates that are to be welded together using a butt joint. The material selected is a PA (nylon) 6 (Durethan B 30 S, manufacturer: Bayer). The necessary material data were obtained from literature or our own measurements. The intensity of the laser beam, the applied pressure and the welding time were specified as welding parameters. The absorptio...

For the simulation, the material values for an amorphous polycarbonate (grade: Makrolon 2805; supplier: Bayer MaterialScience AG, Leverkusen) and a semi-crystalline polyamide (grade: Durethan B 30 S; supplier: Bayer MaterialScience AG, Leverkusen) were employed. Values for the mechanical and rheological characteristics were taken from the material data sheets provided by the supplier. To determine the coefficients of friction, a s...
