Composite Module
Minimum Distance Between Pocket to Panel Edge
Composite structure panels used in aerospace products have a higher strength-to-weight ratio. The minimum distance between cutouts, pockets, and panel edges should be maintained to avoid tearing composite panels. It could affect the load-carrying capacity of the panel and may result in damage during loading conditions. Maintaining a sufficient distance between the cutouts, pockets, and panel edges are always recommended

Minimum Distance Between Insert Hole to Panel Edge
Composite panels are strong and stiff with a higher strength to weight ratio, but their flexible cores are weak and easily damaged. When the insert holes are drilled too close to the panel edges or cutouts, there is a possibility of damaging the core area near the hole due to weak and minimum available core material. Due to this, inserts cannot be appropriately placed, and the core may get dislocated. This could affect the load-carrying capacity of the panel and may result in damage during certain loading conditions. Hence it is always recommended to provide some minimum distance between panel edge and insert holes. As a general guideline, the minimum distance should be 15 mm.
Recommendations:The general guideline suggests that the minimum distance between the insert hole to panel edge should be 15 mm.
