In this work we have studied hadronic charmless two-body B decays involving p-wave mesons in final state. We have calculated branching ratios of B→ AT decays (where A and T denotes a 3P1 axial-vector and a tensor meson, respectively), using B → T form factors obtained in the covariant light-front (CLF) approach, and the full effective Hamiltonian. We have obtained that B(B0 → a1+a2-) =42.47 ×10-6, B(B+ → a1+a20) = 22.71 ×10-6, B(B → f1K2*) = (2.8-4) × 10-6 (with f1=, f1(1285),f1(1420)) for θ_3P1 = 53.2∘, B(B → f1(1420)K2*) = (5.91-6.42) × 10-6 with θ_3P1 = 27.9∘, B(B → K1a2)= (1.7 - 5.7) [1-9.3] ×10-6 for θ_K1 = -37∘ [-58∘] where K1 = K1(1270), K1(1400). It seems that these decays can be measured in experiments at B factories. Additionally, we have found that B(B → K1(1270)a2)/B(B → K1(1400)a2) and B(B → f1(1420)K2*)/B(B → f1(1285)K2*) ratios could be useful to determine numerical values of mixing angles θ_K1 and θ_3P1, respectively.
