||Composite drive shaft produced from joining technology
combined with optimized fiber winding lay-up pattern that is crashable
along the longitudinal axis. Weight
savings: 40-50% compared to 3 joint steel drive shaft.
|Most Innovative Feature:
||Composite-steel yoke Joining technology combined with
optimized fiber winding lay-up pattern which makes composite drive shaft
crashable along the longitudinal axis.
|Other Innovative Features:
||Weight reduction, Reduction in NVH.
|What Forming Process?
|First Time Process Used:
||No. Process itself for making a tube is common.
||Material : Carbon Fiber, Epoxy, Process : Filament Winding
or Pull Winding for making a composite tube.
||No special tooling innovations are required to make a
|New Material Developments:
||Carbon Fiber "TORAYCA T700S" families having
slightly higher Young's Modulus than standard modulus fiber has been
||Approximately 40- 50% compared with 3 joint steel drive
|Direct Consumer Benefit:
||Weight saving, Reduced NVH, Crashworthiness in axial
|Translates to Other Vehicles?:
||Yes. It has already been applied to Mitsubishi Montero and
Mazda RX-8 in addition to Nissan 350Z.
||Significantly reduce peak load during head collision of a
||No concern about durability because NO ADHESIVE is used for
the joining technology. Completely mechanically jointed. Patent protected
in US, Europe and Japan.
