Optimierung der Flammschutzeigenschaften von kohlenstsofffaserverstärkten Kunststoffen

Kurzfassung

The thesis is about the flame retardant optimization of carbon fiber reinforced fuselage structures in the event of a pool fire incident. For this purpose two general concepts, the use of glass formers on a laminate surface and intumescent agents in an intermediate layer, have been followed. Several flame retardants (FRs) have been chosen and tested in a preliminary test using FRs applied to a carbonepoxy prepreg laminate. From the three most promising FRs several samples were manufactured and analyzed in a four minute burnthrough test and a smoke density and toxicity test. To investigate the effect of the FRs on the mechanical properties compression tests were done with flamed and non-flamed specimens for comparison.
