L-726
Woven Prepreg, Aramid Prepreg |
|
|
| Sandwich Properties* |
Core: ¼” cell x 0.004” (6.35 mm cell x 0.10 mm) Aluminum Foil
Adhesive: 1 ply L-310 each side
Facings: 2 plies L-726-281 each side
- RT Flatwise Tensile Strength: 890 PSI (6.1 MPa)
- RT Sandwich Peel Strength: 9 in lb/in (40 N/25 mm)
- *Sandwich peel strength varies with the orientation of the fibers directly against the core and the test direction.
- Fibers laid up parallel with the test direction produce minimum strengths.
- Fibers laid up perpendicular to the test direction produce maximum strengths.
- L-726-281 sandwich peel strength ranges from 7-13 in lb/in (31-58 N/25 mm).
