CarbonCloud The composite bed Denise, Jolien, Katrine & Lilian
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
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
Mechanics ● Tensile strength ● Bending of stiffness ● Deflection ● Shear stress
Manufacturing ● Vacuum bag molding ● Prepreg ● Manually ● Autoclave
Performance and testing ● Quality ● ASTM D790 - Flexural properties ● ASTM D3479 - Fatigue properties ● ASTM D3410 - Compression properties
Future and Eco ● Cheaper materials Natural fibers ○ ○ Dry fibers Other manufacturing methods ○ ○ Solar power for manufacturing Stronger construction ●
Costs ● 25,000 DKK Foam: 18,000 DKK ●
