Therefore, automakers and suppliers must resort to expensive, high-performance plastics. For many applications, cost-effective alternatives are plastics whose properties have been greatly improved by means of treatment with high-energy electron beams. Note de contenu : - Particular challenges in electric vehcicles - Cost-effective alternatives with irradiation crosslinking - The principle behind the procedure - The added value of radiation crosslinking - Applications in electric vehicles - Fig. 1. Crosslinked engineering plastics can be used for many different applications in electric vehicles - Fig. 2. Standard polymers as well as engineering plastics and high-performance polymers can be crosslinked. The process permits treatment of the polymers highlighted in green - Fig. 3 : Trend lines due to irradiation crosslinking for different material properties. Of particular interest for use in electric vehicles are the resulting higher thermal stability and chemical resistance - Fig. 4 : Treatment significantly increases the short-term thermal stability of glass fiber-reinforced plastics – the increase is particularly large with PA6 - Fig. 5 : Fracture surfaces from tensile tests with non-irradiated (left) and irradiated PA6-GF30 (right) under the scanning electron microscope : the matrix remnants on the glass fibers of the irradiated sample indicate the better bond between fibers and matrix polymer - Table 1 : Comparison of mechanical characteristics of non-irradiated and irradiated PA66 (at room temperature / 120 °C) - Table 2 : Comparison of mechanical characteristics for non-irradiated and irradiated PA6-GF30 (parallel / transverse to injection direction) En ligne : https://drive.google.com/file/d/1aWUj2lAlNAXfypGvJDMb6plxIdV6zzxP/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37300 [article]
