We study exclusive non-leptonic two-body $B_c\to(D_{(s)},\eta_c,B_{(s)})+F$decays with $F$(pseudoscalar or vector meson) being factored out in QCDfactorization approach. The non-leptonic decay amplitudes are related to theproduct of meson decay constants and the form factors for semileptonic $B_c$decays. As inputs in obtaining the branching ratios for a large set ofnon-leptonic $B_c$ decays, we use the weak form factors for the semileptonic$B_c\to(D_{(s)},\eta_c,B_{(s)})$ decays in the whole kinematical region and theunmeasured meson decay constants obtained from our previous light-front quarkmodel. We compare our results of the branching ratios with those of othertheoretical studies.Comment: 11 pages, 3 figures, minor corrections, version to appear in PR
