The Great Implosion: Diagnosing & Fixing Our Vacuum Infusion Disaster

Описание: We experienced a dramatic and expensive composite failure: a vacuum infusion imploded our custom box beam, crushing the core. This video is a full debrief and repair guide, showing exactly what went wrong and the method we used to fix it without starting from scratch.

The cause was a pinhole leak in recycled PVC foam core, which allowed the vacuum to collapse the entire structure. We break down the engineering failure and demonstrate the thermoforming repair technique, using heat to reshape the foam and resin before reinforcing it with a secondary laminate. This is a critical lesson in the importance of airtight cores and a masterclass in practical composite repair under pressure.
