Aircraft SeatsWorld Wide Round Robin Testing

• Materials have been ordered 3 sets of 3
  different types of seat materials
• Fire hardened foam (type 1) with dress cover
• Fire hardened foam (type 2) with dress cover
• Foam with fire blocking layer and dress cover
• Informal testing among a small number of labs has
  shown a disturbing lack of consistency in test
  data
• Have requested that no changes be made (as
  recommended by the sub group) until the round
  robin is complete

Damping Material

Damping Material

• Various thicknesses of materials used (sandwich
  constructions)
• Weakest link appears to be the PSA (adhesion to
  the aircraft skin)
• Led to decision to test at interface of the
  damping material adhesive layer and piece of
  sheet metal (simulate aircraft skin)
• Sample size and sample placement is similar to
  mated hook and loop samples

10
Damping Material(continued)

• Requires build up to achieve correct height for
  flame impingement (using Kaowool M boards)
• Somewhat difficult to achieve sample height
• Intermediate scale tests scheduled for July 28 in
  small test rig which was used for the wire tests
  we will be using the foam block as the ignition
  source
