Continuous gas foaming of “Tefzel” ETFE fluoropolymer resin, as presented in this paper, is a practical process for producing foam primaries. Thin-wall foam and foam-skin constructions, with void contents as high as 70 percent, have been made at high speed using this technique. Foam primaries are generally used in twisted pair, computer network cables.

This report describes a four phase study to identify potential fuel containment concepts for transport category aircraft. The study includes a review and evaluation of: Accident crash test Design; guidelines, Design procedures State-of-the-art technology Design studies and conclusions and analyses data specification and criteria. A literature survey was performed and the relative contributions from 53 documents are noted. Transport airplane data are summarized including the results from full-scale airplane crash tests and section tests. Analyses results which depict dynamic pulses are presented. Several reports including the U.S. Army Crash Survival Design Guide and the Special Aviation Fire and Explosion Reduction (SAFER) Advisory Committee areidiscussed in detail. Several fuel containment structural design concepts are evaluated with regard to both wing and fuselage usage. The state-of-the-art technology is summarized in this report. Included in this summary is a priority ranking of approaches. A selection of approaches is described. The selected concepts are reviewed with regard to benefit and penalties. The concepts are prioritized in order of effectiveness.

This report contains the results and evaluation of a propane burner developed by Airbus Industries for burnthrough resistance tests of cargo liner joints, seams and fasteners, as required by Federal Aviation Regulation (FAR) 25.857, effective June 16, 1986. Measurements of temperature and heat flux were obtained durng a typical calibration procedure. These values, along with the results of several test samples utilizing the propane burner, are compared to the results obtained through identical calibration procedures and sample tests using the 2-gallon per hour kerosene burnr specified in the final rule.
