The　integration　of　outstanding　flame　retardancy　and　electromagnetic　interference　shielding　effectiveness　(EMI　SE)　in　polymers　is　highly　desirable　for　practical　applications.　In　this　work,　thermoplastic　polyurethane　(TPU)　composites　loaded　with　silicon　wrapped　ammonium　polyphosphate　(SiAPP)　and　short　carbon　fiber　(SCF)　were　prepared　through　melt　blending　method.　Then,　a　novel　air-assisted　thermocompression　technology　independently　developed　by　our　group　was　employed　to　fabricate　multifunctional　sandwich-structured　TPU/SiAPP/SCF/　Ti3C2Tx　MXene　composites.　The　peak　of　heat　release　rate　and　the　peak　of　smoke　release　rate　of　TPU　composites　containing　20　wt%　SiAPP　and　20　wt%　SCF　were　decreased　by　72.5%　and　49.7%,　respectively,　compared　to　those　of　pure　TPU.　The　sandwich　structure　endowed　the　TPU　samples　with　high　EMI　SE.　For　instance,　the　TPU/　SiAF20/MXene　SW-1.02　mm　composite　inserted　with　the　Ti3C2Tx　MXene　layer　exhibited　the　averaged　EMI　SE　of　50.5　dB.
