This kind of defect happen due to volatile resin components, or air not properly controlled

during cure.

• Delamination

• Porosity

• Cracks

• Misalignment

It occur in the bondline due to incorrect cure conditions for the adhesive or contamination of the surfaces to be bonded.

• Ply cracking

• Ply Misalignment

• Bonding Defect

• Fiber Misalignment

This is produced as a result of mistakes made in lay-up of the component plies.
