General Composites Manufacturing Notes

EA 9340 Guidelines

For Adhering Skins to Core

• Roughly 250g glue (not hardener) per 24 sqft of area is the minimum
• More may be required if the skins have wrinkles in them
• Weight is applied via rigid panel and physical weights (i.e. thick plywood + buckets of water)

For Fillets

• Roughly 100g glue (not hardener) per 120 inches (one side) of fillet (0.35" radius)
• 5 shots of milled glass per 100g glue to thicken at minimum
• Sand fillet area and tape off outside fillet area before gluing. Apply a thin film of glue on normal surface, but most of the strength comes from the fillet (promotes shear loading)
