Microwave　heating　technology　is　currently　a　prominent　area　of　research　in　the　field　of　composites　curing　due　to　its　advantages,　including　selective　heating,　energy　saving　and　high　efficiency.　However,　the　uneven　distribution　of　electric　field　inside　the　cavity　leads　to　asynchronous　heating　of　composite　components.　This,　in　turn,　results　in　severe　deformation　and　curing　defects,　posing　a　major　challenge　that　hinders　the　widespread　industrial　application　of　microwave　process.　In　this　paper,　by　combining　nonlinear　electromagnetic　constitutive　equations　and　power　density　functions,　the　correlation　between　the　uniformity　of　electric　field　and　the　temperature　distribution　in　composite　components　during　microwave　heating　was　elucidated.　Finite　element　simulations　were　employed　to　investigate　the　influence　of　various　regulation　methods,　such　as　the　setting　of　generators,　the　introduction　of　mode　stirrers,　and　the　relative　movement　of　loading　platform,　on　the　uniformity　of　electric　field　distribution.　An　experimental　apparatus　for　regulating　microwave　heating　uniformity　was　independently　designed　and　developed,　and　a　series　of　experiments　were　conducted　to　validate　the　accuracy　of　the　simulation　analysis　and　investigate　the　temperature　variation　in　microwave-cured　components　under　different　regulation　modes.　Finally,　an　analysis　was　performed　on　the　influence　of　temperature　distribution　during　the　curing　process　on　the　performance　of　composites.　©　2023,　Central　South　University.
