EC! Laminate Sample #15:
- Reinforcement: 6oz woven carbon, 12oz biaxial carbon
- Resin: Proset 135 / 210 epoxy
- Core: 5/8″ M100 Gurit Corecell
Panel weight: 12.5 oz per square foot / 3.84kg per square meter
Thickness 0.65″ / 16.5mm
Overview:
This laminate sample demonstrates how to get nice light high-performance cored composite panels with a careful bagged wet-layup process. Using sheet plastic and scrap vacuum bag to sandwich the wet-out carbon allows for a very controllable resin content and easy handling. It may be overkill for a flat panel – but this process really makes complicated secondary bonding and wet-layup projects easier and neater. Resin content here is comparable to a carefully infused panel but there is probably 10% more resin that a similar pre-preg panel would require. This Proset 135 resin works best with a post-cure and for structural applications that would be a good idea.

Things to Improve:
Less trash? Really the big down side here is the extra junk created by using plastic backer for the layup. Almost as bad as pre-preg.
