Ultramid® B3WG6 CR (Crash Resistant) PA6 (Polyamide 6) - Fiber™ Design Process: Pedestrian Protection - Lower Bumper Stiffener
|
Performance Solutions:
Since October 1, 2005, pedestrians in Europe can walk the
often busy city streets with a little more confidence.
EuroNCAP (European New Car Assessment Program) has
been conducting pedestrian protection studies on new vehicles
for just over two years. To meet the requirements of
EuroNCAP and other regulatory agencies, the design
concept of a vehicles’ front end now faces intense scrutiny.
Manufacturers, too, have a set of requirements that must be
met: optimal space utilization, ease of assembly, sturdiness
upon contact with objects, etc.
Enter Ultramid® BWG6 CR (Crash Resistant), a stable glass filled PA6 (nylon
6) engineering resin that provides the right level of performance
that minimizes pedestrian impact. The lower bumper
stiffener or LBS weighs just over two pounds, is three feet
long and is installed behind the front bumper so as to diminish
the risk of serious knee injury in the event of a collision with a
pedestrian.
Using our Fiber™ design process and Ultramid® B3WG6 CR
the performance of the LBS can be modeled accurately.
Fiber™ uses an integrative simulation, that combines a classic
mold-fill simulation with experimental data obtained from a
special high-speed measuring device made by BASF. The
accuracy of the Fiber™ integrative simulation minimizes the
need for prototype testing and can shorten the design cycle
considerably.
Benefits for Parts Manufacturers &
Injection Molders include:
 |
Fiber™ simulation reduces tests |
|
Shortened design cycle |
|
Lower repair costs in accident situations |
