Cubit™ - 3D knit fabric for car seat

Image
Challenge
  • Realization of breathability and cushioning
  • Reduction of space
Insight
  • Body pressure dispersion by MF
  • Surface stiffness of 3D knit structure
  • 3D mesh structure
Result
  • Reduction of fatigue on long time driving
  • Feasibility of shin sheet
  • Recyclability (PET 100%)

Product Feature of Cubit™

1. Good Cushioning - The knit fabrics realize good cushioning in a state pulled with a frame because knit fabric makes moderate elasticity and extensibility of vertical and horizontal.

2. Pressure dispersion in thickness direction – The knit structure supports weight on a large area that take advantage of recoverability of monofilament yarn connecting front and middle yarn.

  • Sound-absorbing frequency isn't suitable.
  • Current coustic materials are heavy and thick.
Insight
  • PreciseTM is multiplied to current acoustic materials such as felts and ulethanes etc.
Image
Result
  • Improve sound absorptivity.
  • Can controll Sound-absorbing frequency
  • Can make acoustic materials thinner and lighter.

Product Features of Precise™

1. Precise™ Improves sound absorbing performance. Make acoustic materials thinner and lighter.

Image

2. Precise™ changes the peak of the spectrum by selecting a type.

Image

3. Precise™ can be used for various acoustic materials.

Weight Reduction

Continuous Glass Fiber Reinforced Polyamide Resin

Image
Challenge
  • Increasing demand of light-weight automobiles.
Insight
  • Metal replacement by high performance composites
  • Multi functionalization by combination with other materials
Result
  • Weight reduction of various parts like framework, sheet, impact absorption and insulationg parts.
  • Reduction of parts and processing engineering

Product Features of Continuous Glass Fiber Reinforced Polyamide Resin

1. Weight reduction and parts reduction:
Steel bumper beams require post-processing such as bending or welding to another component. Integral molding using Continuous Glass Fiber can reduce not only weight, but also the number of processes and parts.

3. Excellent NVH:
Sound absorption and insulation characteristics obtained by combining the resin with polyamide foam SunForce™ (AM). The combination of the two materials further improves impact resistance. Furthermore, changing the thickness of the foam material can change the sound absorption frequency band.


Eco-friendly Tyre

TUFDENE™ - S-SBR (Solution Styrene-Butadiene Rubber)

Image

Development Roadmap of TUFDENE™

1. Improve overall tyre performance by functionalization technology.

2. Continuous S-SBR has an advantage of wear resistance and handling properties due to higher MW.

3. Asahi Kasei’s new 5th generation (both end) functionalization to further enhance wear resistance and rolling resistance (RR).
