This　study　presents　experimental　results　of　femtosecond　laser　(lambda　=　1030　nm,　tau　=　800　fs)　ablation　of　AA2024,　sintered　SiC,　and　SiC-particulate-reinforced　aluminum　metal　matrix　(SiCp/AA2024)　composites　using　a　scanning　method.　The　aim　is　to　determine　the　mechanism　of　femtosecond　laser　ablation　of　SiCp/AA2024　composites　by　a　comparative　study.　Scanning　electron　microscopy　and　energy-dispersive　spectroscopy　reveal　the　morphological　changes　in　the　ablated　surface　with　increasing　pulse　fluence.　The　ablation　depth　and　surface　roughness　measured　by　a　3D　surface　profiler　indicate　interfacial　interaction　between　the　AA2024　matrix　and　SiC　particles.　Two-temperature　modeling　(TTM)　was　applied　to　analyze　the　ablation　behavior　of　Al　and　SiC.　The　experimental　results　and　TTM　analysis　indicate　that　the　femtosecond　laser　ablation　of　the　SiCp/AA2024　composites　and　the　interface　interaction　in　the　composites　under　laser　irradiation　are　due　to　matrix　ablation　enhanced　by　the　Fresnel　effect　and　electromagnetic　interaction　(rather　than　thermal　interaction)　at　the　particle/matrix　interface.
