Laminating a Bulkhead Penetration with a 3D-Printed Plug Every hole through a structural bulkhead is a weak point unless it’s reinforced properly — and reinforcing it properly starts with a plug that comes back out again. Matching laminate to the surrounding skin The basic rule for reinforcing a penetration is straightforward: match the laminate going […]
