As a result, this component must be dimensionally stable and meet tight tolerances. Long glass fiber-reinforced ABS has proven to meet all part performance requirements at considerably lower weight in comparison the currently used cast magnesium. Note de contenu : - Comparisons with polypropylene and polyamide - Development and implementation - Fig. 1 : The stiffness of the ABS LGF material in relation to glass content and temperature - Fig. 2 : The stiffness of different long glass fiber-reinforced thermoplastics shows that PP with the same fiber content achieves significantly less tensile modulus of elasticity - Fig. 3 : After water absorption (conditioning), the tensile modulus of elasticity decreases less with ABS alloy than with PA6 alloy - Fig. 4 : The original geometry and space available for the stiffening ribs - Fig. 5 : The topology optimization results in red highlight the areas that require ribbing. In the lower right area, the calculated rib pattern is clearly visible - Fig. 6 : In the updated part geometry, the yellow lines show the stiffening ribs added to the original design of the part - Fig. 7 : Fill image calculation of the molded part with the hot/cold runner system En ligne : https://drive.google.com/file/d/1PitwDhGHAlazmLWE06iJo7SMb_zxjClj/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=32119 [article]
