| Integrated head rest for child car seats made of NYLAFORCE® B 50 |
|
 |
|
The more stringent requirements for head supports on
child seats led to the selection of NYLAFORCE® B 50
for the development and manufacture of the integrated
headrest for the "RECARO start" child´s seat. The
forces of acceleration occurring during a side impact
crash require a material with high kinetic absorption
properties combined with the highest strength. |
|
| On the one hand the head supports may not break in case of a crash, on the other a high
level of dimensional stability (stiffness) must be guaranteed. Qualities that in principle are
contradictory but which are mastered without difficulty by NYLAFORCE® B 50. Despite
the high level of glass fibre reinforcement, processing NYLAFORCE® B 50 presents no
problems. Moreover, the material stands out thanks to its high thermal resistance and low
moisture absorption compared with standard polyamides. |

| Car seat back made of NYLAFORCE® B 50 Z |
|
 |
|
Excellent toughness with the greatest strength and
rigidity. These are the outstanding properties of the new
NYLAFORCE® B 50 Z high-performance compound
produced by using feed up-process. The material was
specially developed for car seat backs and seat shells.
In this application, special demands were made in terms
of shape stability and the material’s fragmentation |
|
characteristics. A further basic requirement for realising this application was the
outstanding quality of the surface of this highly-reinforced polyamide since the
components are not further painted or coated.
Chair backs are subjected to extreme stress tests. Besides front and rear crash tests,
they must also pass the critical "protection from loads" test. In this test the impact on the
front seats of objects in the back of the car is simulated. All forces generated in a crash
must be taken up and absorbed by the seat back and bottom or be conducted via the bolt
connections to the bodywork since the bottom and back components contain no additional
metal supports. |
|
| NYLAFORCE® B 50 Z was a clear winner in the selection of materials compared with all
other plastics including long fibre reinforced polyamides and highly reinforced semi-
aromatic plastics. NYLAFORCE® B 50 Z impresses with its simple processing and an
excellent component surface. |

| Central armrest for the BMW 1 series made of NYLAFORCE® B 60 |
|
 |
|
For the manufacture of the central armrest on the BMW
1 series, the decision was made for NYLAFORCE® B
60. During the selection process, the material clearly
stood out against other highly reinforced materials such
as long glass fibre reinforced polyamides and highly
reinforced, partly aromatic plastics. In particular, its good
toughness combined with the highest strength was de- |
|
| cisive in selecting NYLAFORCE® B 60. It even met the requirement for a material with
good paintability without any problem. |

| Car door handles made of NYLAFORCE® B 60 |
|
 |
|
Door handles for cars have to withstand a practical test,
in which a force of 2000 N is applied to the handles.
They may not break under the test. Alongside the
mechanical function, good paintability is also required.
NYLAFORCE® B 60 easily meets these requirements.
Despite being reinforced with 60% glass fibre, the
surface is totally smooth and clean. |
