Flammability

Self Extinguishing per FAR part 25.853

Sandwich Properties*

Core: ¼” cell x 0.004” (6.35 mm cell, x 0.10 mm) Aluminum Foil Facings: 2 plies L-951-3K70P each side RT Flatwise Tensile Strength: 900 PSI (6.2 MPa) RT Sandwich Peel Strength: 6 in lb/in (27 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-951-(7 mil) sandwich peel strength ranges from 5-7 in lb/in (22-31 N/25 mm).
