| Résumé : |
Replacing metal with polyamides (PA) in components can not only reduce weight and costs, but also offers ‧developers greater design freedom. However, this requires materials with improved mechanical properties. A new PA6 series with greater stiffness and strength meets these requirements, not only as a substitute for metals but also replacing PA66 in components. |
| Note de contenu : |
- Combining the advantages of PA6 and PA66
- Alternative to PA66-GF50
- 20 percent higher energy absorption in a crash
- Improved property profile with good aging resistance
- Fig. 1 : Profile of elastic modulus against temperature for Ultramid B3WG7 XP BK23346 in comparison with a PA6-GF35 and a PA66-GF35 in the dry and conditioned states : the material has similar values to a PA66 over the entire temperature range
- Fig. 2 : Tensile strength against temperature for Ultramid B3WG7 XP K23346 in comparison with a PA6-GF35 and a PA66-GF35 in the dry and conditioned states : the tensile strength is clearly above that of a standard PA6 and is comparable to that of a PA66
- Fig. 3 : Comparison of notch impact strength (left) and impact strength (right) at room temperature and at -30°C between Ultramid B3WG7 XP
BK23346 and a PA6-GF35 and PA66-GF35 respectively : in both cases, the material surpasses the comparison materials
- Fig. 4 : A 3-point bending test showed that the maximum necessary work of fracture for Ultramid XP grades which exceeds that of com¬parable PA6 and PA66 grades
- Fig. 5 : For crash tests, so-called "crash domes"were driven against a metal wall at 8.5 m/s.The domes made of Ultramid XP achieved high energy absorption values
- Fig. 6 : In the crash tests, the Ultramid XP products show an approximately 20% higher energy absorption in each case compared with the corresponding standard products
