Carbon filaments disseminated into the environment by combustion of carbon fiber/resin composites threaten electrical and electronic equipment, including power distribution and communications systems. The anticipated use of such composites in structural parts of aircraft, automobiles, and con sumer goods requires that the hazard be minimized in the inevitable events of flaming aircraft and auto crashes and other incinerations. The electrical hazard is mitigated by combustion promotors, and several substances have been evaluated in this role. The decreasing order of effectiveness among the species studied is PbO, Pb[OOC(CH2)8COO(C8H17)] 2, Pb3O4, Bi2O2CO 3,Bi2O3, Bi, CuO, CaCO3, Ca(OOCCH 3)2 H2O, Sb2O3. The lead compounds are not significantly separated in rank, and the ranking of CuO in the list is somewhat uncertain. Sb2O3 shows no activity as a combustion promotor. [ABSTRACT FROM PUBLISHER] |
