Site na nyocha bụ isi, e kwubiri na:
(1) Mgbe ọdịnaya graphite (ọnụọgụ uka) na brik carbon carbon na-erughị 10%, nhazi nhazi ya nwere Al2O3 na-eme ka matrix na-aga n'ihu, na carbon jupụtara na matriks n'ụdị ihe kpakpando. N'oge a, thermal conductivity λ nke aluminum carbon brik nwere ike dị ka gbakọọ site usoro (1)
Na usoro, λa bụ thermal conductivity nke Al2O3; Vc bụ akụkụ dị nta nke graphite. Nke a na-egosi na ọkụ eletrik nke brik carbon carbon enweghị ihe jikọrọ ya na conductivity thermal nke graphite.
(2) Mgbe graphite nụchara anụcha, thermal conductivity nke aluminum carbon brik nwere obere adabere na graphite ahụ.
