Aircraft Seats World Wide Round Robin Testing

This report presents the ongoing round robin testing of various aircraft seat materials conducted by Pat Cahill. Three sets of different seat materials, including fire-hardened foam types and foam with fire-blocking layers, have been ordered for assessment. Issues with consistency in informal test data have been noted, leading to a recommendation to pause changes until testing is completed. Additionally, damping material tests focusing on adhesion to aircraft skin and flammability tests for aircraft wiring are discussed, with findings and further test schedules outlined.

  1. Aircraft SeatsWorld Wide Round Robin Testing Pat Cahill

  2. 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

  8. Damping Material Pat Cahill

  9. 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
