3.3.1. Determination of the critical load
Fig. 5(a) and (b) shows the MK-0752 of critical loads versus MoS2weight fraction added to the polyester or epoxy matrices. We might deduce that the addition of MoS2 to the polyester or epoxy matrix leads to a significant decrease of the critical loads (Lc1, Lc2 and Lc3). For the neat polyester powder coating, only the first two failure events occurred compared to the neat epoxy in which no critical damage events were detected. Indeed, the damage initiation and propagation (Lc1 and Lc2) kinetics are more obvious in the case of polyester matrix compared to endodermis shown in the epoxy matrix.
