  1. CarbonCloud The composite bed Denise, Jolien, Katrine & Lilian

  2. Design Design objectives: ● Minimize the costs Design constraints: ● Mattress seating: 200 x 90 cm. Max. weight: 20 Kg. ● ● Max. load: 300Kg. ● Max. deflection 6 cm. ● Good looking

  3. Fibers and matrix Composite: Epoxy/carbon fiber, UD prepreg, UD lay-up Optimal ratio Young/shear ● modulus ● Look and feel Foam: Divinycell H250, 8 mm thick, PVC/ Polyurea ● Highest shear strength ● Most used

  4. Mechanics ● Tensile strength ● Bending of stiffness ● Deflection ● Shear stress

  5. Manufacturing ● Vacuum bag molding ● Prepreg ● Manually ● Autoclave

  6. Performance and testing ● Quality ● ASTM D790 - Flexural properties ● ASTM D3479 - Fatigue properties ● ASTM D3410 - Compression properties

  7. Future and Eco ● Cheaper materials Natural fibers ○ ○ Dry fibers Other manufacturing methods ○ ○ Solar power for manufacturing Stronger construction ●

  8. Costs ● 25,000 DKK Foam: 18,000 DKK ●
