What could potentially happen if deburring is not assessed carefully on composite materials?

Deburring is a critical step in the preparation and finishing of composite materials. When this process is not assessed carefully, it can lead to delamination, which is the separation of layers within a composite structure. This can happen when the integrity of the material is compromised during the deburring process, potentially causing raised edges or uneven surfaces. These imperfections may not only weaken the bond between layers but also compromise the overall structural integrity of the composite.

Delamination can result in a loss of strength and stiffness, which are essential properties for aerospace applications where safety and performance are paramount. The presence of delaminated areas could lead to failure in service, which poses significant risks during flight and operation.

While increased costs may arise from remedial work caused by improper deburring, the most direct and critical consequence of neglecting careful assessment during this process is indeed delamination, making it the most relevant outcome in this context. Improved performance cannot reasonably result from mishandling the deburring process, and claiming that there are no repercussions overlooks the serious engineering implications involved.
