Reminder
 What is Technical Textile ?
• According to the Textile Institute : ‘Textile materials and
products manufactured primarily for their technical
and performance properties rather than their
aesthetic and decorative characteristics.
• Technical textiles used in the transportation sector are
called “MOBILTECH”.
• Mobiltech covers insulation and safety aspect, comfort and
style but also focuses on fuel economy.

The Market: Why Composites ?
 Volume growth in automobile
12
The Market: Why Composites ?
 Example of success:
• BMW i3
 Carbon fiber body & new aluminium
“drive module” = 550 pounds saved
compared with a steel structure
 Lightweight structure increases battery
autonomy
 130 carbon-fiber part vs 400 for a steel
body.
 Better process & less parts help
offsetting the raw material cost
