| Résumé : |
The conditions in electric vehicles place high demands on the materials used. 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) |
