MECH 6521. MANUFACTURING OF COMPOSITES
3. • Resin degradation
• Moisture
Prevent defects
in the final part
• Design a symmetrical
laminate
Mitigate residual
thermal stresses
MECH 6521. MANUFACTURING OF COMPOSITES
Voids
Ply orientation

OUT-OF-
AUTOCLAVE
AUTOCLAVE
The pressure from the autoclave helps to consolidate
the composite lamina and collapse voids created
from entrapped gases.
The available pressure is significantly reduced, so
other means of evacuating air must be exploited
5. MECH 6521. MANUFACTURING OF COMPOSITES
simultaneous cure of a stiffener and a skin
The interface between the two parts may or
may not have an adhesive layer
increase fatigue and peel resistance
Co-cured skins
poorer mechanical properties
poor panel surface quality
