Sandwich Properties*

Core: ¼” cell x 0.004” (6.35 mm cell x 0.10 mm) Aluminum Foil Facings: 2 plies L-501-7781 each side RT Flatwise Tensile Strength: 1,300 PSI (9.0 MPa) RT Sandwich Peel Strength: 10 in lb/in (44 N/25 mm) *Sandwich peel strength varies with the 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. L-501-7781 sandwich peel strength ranges from 7-13 in lb/in (31-58 N/25 mm).
