主　　题：Inclination angle Flake powder metallurgy Thermal conductivity model Metal matrix composites 

摘      要：The inclination angle of the flake particle has a significant impact on the in-plane thermal conductivity of *** graphite flake/Al composites(50 vol%)with different inclination angles were fabricated via flake powder metallurgy,and the results show that with increasing the size of Al particle from 25.6 to 50.7μm,the inclination angle of graphite flake decreases from 7.3°to 4.4°,while the in-plane thermal conductivity of composites increases from 473 to 555 Wm-1 *** on the rules of mixture,an effective model was established to qualify and quantify the relation between the inclination angle and the in-plane thermal conductivity of the corresponding *** model can also be applied to other flake particle-reinforced composites.
