Abstract:

A series of tests was conducted to determine the effect that concentrations of hydrogen below its lower flammability limit can have on the burning of other materials. The vertical Bunsen burner test cabinet was set up to run tests with hydrogen concentrations varying between 0% and 4% by volume. Three different materials were tested: a 1/16″ thick woven carbon fiber, a fabric aircraft seat cover, and an 8-ply unidirectional carbon fiber. All three materials showed significantly increased after-flame times and burn lengths as the concentration of hydrogen increased. The burn rate of both carbon-fiber materials also significantly increased with increased hydrogen concentrations, whereas the burn rate of the seat-cover fabric remained relatively constant for all concentrations.
