L-530
Solution Coated Epoxy Prepreg |
|
|
| Sandwich Properties* |
Core: Aramid Phenolic, 3 lbs/ft3, 1/8” cell (16 kg/m3, 3.175 mm)
Facings: 1 ply L-530-7781 each side
- RT Flatwise Tensile Strength: Core Failure
- RT Sandwich Peel Strength: 15 in lb/in (67 N/25 mm)
- *Sandwich peel strength varies with orientation of fibers directly against the core and test direction.
- Fibers laid up parallel with the test direction produce minimum strengths.
- Fibers laid up perpendicular to the test direction produce maximum strengths.
