How can a change in the lamination schedule affect a composite part?

A change in the lamination schedule can significantly impact the structural integrity and performance of a composite part. By adjusting the schedule, you are essentially altering the layers of materials, their orientation, and thickness, which directly influences the mechanical properties of the final product.

In particular, a poorly executed lamination schedule can lead to inadequate bonding between layers, which not only reduces the overall strength of the composite but can also increase the risk of delamination. Delamination occurs when the layers of the composite separate due to insufficient adhesion or structural stress. This separation compromises the integrity of the part, making it vulnerable to failure under load.

Opting for a different lamination schedule could potentially lead to inconsistencies in curing times, overlap of resins, and variations in fiber orientation, all of which may contribute to the weakening of the composite material, thereby increasing the chance of delamination under operational stresses or environmental conditions. Therefore, option B accurately describes the risks associated with modifying the lamination schedule in composite manufacturing.
