october 9-10, 2002 CEAT/SEI MINISTÈRE DE LA DÉFENSE MATERIALS IN HIDDEN AREAS 1-MATERIALS CURRENTLY USED IN COCKPIT AND CABIN TWO THERMOPLASTICS LAMINATED PANEL GLASS/PHENOLIC-2PLIES SANDWICH PANEL NIDA NOMEX+ 4 PLIES GLASS/PHENOLIC

october 9-10, 2002 CEAT/SEI MINISTÈRE DE LA DÉFENSE MATERIALS IN HIDDEN AREAS 2- Combination of an insulation blanket film pvf + 30 wires bundled with attachment clamps made of polyamide the attachment clamps meet the requirements of the vertical bunsen burner test 12 seconds

october 9-10, 2002 CEAT/SEI MINISTÈRE DE LA DÉFENSE MATERIALS IN HIDDEN AREAS RADIANT PANEL STANDARD TEST METHOD SIZE OF THE SPECIMEN : 15x 12 cm

october 9-10, 2002 CEAT/SEI MINISTÈRE DE LA DÉFENSE MATERIALS IN HIDDEN AREAS IGNITION TIME : 60 seconds SIZE OF THE SPECIMEN: 50 X 17, 5 cm

october 9-10, 2002 CEAT/SEI MINISTÈRE DE LA DÉFENSE MATERIALS IN HIDDEN AREAS TESTS ON WIRES + ATTACHMENT CLAMPS + INSULATION BLANKETS FIRST RESULTS A LOT OF DISPERSION - 14 or 30 wires bundled located on blanket with 2, 3 or 4 clamps separated at 2 to 5 cm - clamps melted after removing the pilot burner - The flame remains or not afterwards.

october 9-10, 2002 CEAT/SEI MINISTÈRE DE LA DÉFENSE MATERIALS IN HIDDEN AREAS In some hidden parts the space out between two attachment clamps is less than 1,5 cm scenario : 30 wires bundled + 5 clamps separated every 1 cm and located on the insulation blanket
