Flexible　sandwich　structure　materials　with　metal-rubber　damping　core　have　the　advantages　with　stable　basic　wire　material,　high　damping,　combined　stiffness　and　flexibility,　low-cost　production　and　so　on.　Due　to　the　special　microstructure　with　space　woven　wire　mesh,　they　can　exhibit　excellent　dry　friction　damping　characteristics　and　thermal　protective　performances.　It　is　vital　for　the　defense　and　high-level　components　serving　in　complex　or　extreme　conditions.　However,　the　key　problems　including　the　poor　consistence　between　fabrication　technology　and　mechanical　performance,　and　the　unsure　relationship　between　microstructure　and　performance　have　not　been　solved.　This　hampers　the　performance　optimization　and　mass　production　application　of　flexible　sandwich　structure　materials.　In　this　paper,　the　research　progress　of　flexible　sandwich　structure　materials　with　metal-rubber　damping　core　is　comprehensively　reported.　The　typical　microstructures　of　metallic　wire　mesh,　woven　processes,　macroscopic　and　mesoscopic　constitutive　models,　numerical　modelling　technologies,　full-field　measuring　technologies　and　some　engineering　applications　are　introduced.　The　manufacturing　problems　and　thermo-vibration　responses　are　decomposed　respectively.　The　research　prospects　and　potential　applications　on　the　extended　structure　materials　are　presented.　©　2022　Cailiao　Daobaoshe/　Materials　Review.　All　rights　reserved.
