Abstract:

 Six kinds of bio-foams (labeled as GG, GY, GZ, PG, PY and PZ successively) were designed and fabricated by using the mycelium of Ganoderma lucidum and Pleiatus ostreatus with the plant debris mainly composed of fruit trees, poplar and bamboo, and the fire resistance characteristics were studied. The results showed that, the carbon formation rate and flammability of bio-foam GG and PY were preferable. After 33 s, the heat release rate reached the peak value of (204.46±11.38) kW/m². The total heat release showed a trend of fast to slow with time. After 540 s, the production of CO increased rapidly. And the smoke production was evidently at initial phase for the antiflaming of mycelium. The fire resistance of mycelium bio-foam is comparable to or even better than that of general thermal insulation foam, and its flame retardancy needs to be improved furtherly.
