TROY, Mich., March 3 /PRNewswire/ -- After the perennial top concern over
cost reduction, safety is rated as the number one challenge among automotive
engineers to stay competitive in the design of the next generation of motor
vehicles, according to the 10th annual DuPont sponsored survey of those
planning to attend the 2004 SAE World Congress and Exposition, March 8 - 11.
The DuPont SAE survey results also ranked advanced safety and entertainment
systems as virtually tied among the top two technologies consumers would be
willing to pay for in their next vehicle.
    "The SAE survey results support double-digit growth projections for safety
systems development and validates our experiences around the world with first
tier and OEM customers," said Michael L. Sanders, global business director for
DuPont and INVISTA(TM) Automotive Safety Systems.  "Our primary focus is to
contribute materials technology and the expertise to apply it in priority
development programs for side impact and rollover protection as well as
collision avoidance and pedestrian protection systems that are on the near-
term horizon."
    DuPont and INVISTA, the DuPont textiles unit that maintains a safety
systems marketing alliance with DuPont, will participate in the 2004 SAE
Exposition at booth 1643 with a focused display of automotive safety materials
technologies.  Technical experts from both companies will be available to
consult with attendees on ways they can achieve their engineering design goals
at lower cost, space and weight.
    The 2004 SAE study report indicates that the top 10 safety systems to
receive priority attention among first tier suppliers and OEMs over the next
five years will include the following:
    * Collision avoidance systems - 62 percent "high" attention
    DuPont is developing applications for its electronic and communications
technologies including ceramic and precious metal paste microcircuit materials
for weight- and space-savings and greater durability in "bluetooth" wireless
communications, radar, infrared and other warning systems.  DuPont engineering
polymers, such as DuPont(TM) Crastin(R) PBT and DuPont(TM) Zytel(R) nylon,
will be used to house and encapsulate sensors and control modules.  New
display materials and methods are available, including the DuPont(TM)
SentryGlas(R) Wedge(TM) that enables sharper head-up display images in
windshields.
    * Side and rear air bag systems - 56.5 percent "high" attention
    Redesign of side air curtains, knee and rear air bag systems will be
undertaken to integrate deployment components, and as a result, save weight
and cost through the use of a variety of DuPont plastics technologies.  System
deployment and occupant sensors rely on DuPont electronic materials such as
DuPont(TM) Pyralux(R) flexible circuitry and DuPont(TM) Kapton(R) polyimide
film, DuPont microcircuit materials and engineering plastics.  DuPont(TM)
Hytrel(R) TEEE and new DuPont(TM) Advantech(TM) TPO resins are used for air
bag deployment doors.  INVISTA, a leading supplier of air bag nylon fiber, is
a DuPont marketing partner in pursuing the development of air bag systems.
    * Active seatbelt pre-tensioning systems - 43.5 percent "high" attention
    DuPont is a current leader in supplying engineering plastics such as
Crastin(R) PBT and DuPont(TM) Rynite(R) PET thermoplastic polyester,
DuPont(TM) Delrin(R) acetal, Zytel(R) nylon and other resins for seatbelt
retractor mechanisms, buckles and electric motor components.
    * Pedestrian protection systems - 41 percent "high" attention
    The first phase of the European Union Directive for vehicle and pedestrian
safety standards will be implemented in 2005.  In addition to frontal air
bags, auto engineers are testing crush cones and honeycomb structures of
DuPont engineering plastics for improved bumper and interior compartment
impact absorption.  The technology is aimed at providing tunable impact
absorption in ways that foam technology cannot.
    * Electronic stability control - 39 percent "high" attention
    Harnessing control of multiple vehicle systems to increase driver control
and reduce rollovers through electronic stability systems will require a range
of DuPont electronics and polymer technologies for optimum reliability and
cost-benefit.
    * Side door reinforcement and impact absorbers - 36 percent "high"
      attention
    A critical need for side impact protection and for matching smaller and
larger vehicle crash compatibility is the potential to increase intrusion beam
performance, combined with interior and door panel impact protection -- all
within a limited space.  Composite structures of DuPont(TM) Kevlar(R) aramid
fiber and a variety of crush cone, honeycomb and bladder concepts in DuPont
engineering plastics offer potential.
    * Tire pressure monitors and run-flat tires - 36 percent "high" attention
    Wheel rim sensors and wireless communication electronics are being
employed to meet the mandate for measuring and alerting drivers to tire
pressure levels.  DuPont microcircuit materials can be used in the sensors and
to facilitate the "bluetooth" wireless communication.  DuPont(TM) Zytel(R)
nylon is used to house a commercial tire pressure sensor.
    * Side, overhead and rear laminated safety glass - 22 percent "high"
      attention
    NHTSA studies indicate that laminated glass could be a major factor in
reducing the toll of 10,000 occupant ejection fatalities each year in the
United States alone.  DuPont(TM) SentryGlas(R) Plus safety glass interlayer
offers added rigidity and tear strength for side windows to keep side windows
in place and to deter thieves of vehicle contents.  It is commercially used as
an option on both the BMW 5 and 7 Series models.  New SentryGlas(R) technology
will be debuted at SAE for its additional benefits in providing acoustic,
solar and styling benefits in addition to safety and security.
    * Head-up display systems - 18 percent "high" attention
    DuPont is the leader in supplying a partial wedge-shaped interlayer for
windshield laminated safety glass that allows head-up display (HUD) systems to
present a cleaner, sharper image for increasingly critical driver information
such as turn-by-turn navigation and collision avoidance warnings.  Future HUD
systems will save space and weight by employing a variety of DuPont
electronics and plastics technologies as they place critical information in
the driver's view of the road ahead.
    * Inflatable seat belt systems - 16 percent "high" attention
    Another opportunity, especially for rear passenger protection, is seen in
"belt-in-bag" systems.  These systems would rely upon the extensive DuPont
materials technology offering that enables seatbelt mechanism and air bag
deployment and electronic sensor performance.
