AB  - It is still a big challenge to prepare polymer/layered double hydroxide (LDH) 
      composites with high performance, due to the strong agglomeration tendency of 
      LDHs in the polymeric matrix. In this study, to avoid the agglomerated situation, 
      the orientated LDH nanosheets were vertically grown on a ramie fabric surface, 
      which was then embedded in unsaturated polyester resin (UPR) through the 
      combination method of hand lay-up and vacuum bag. Due to the increased contact 
      area and the restricted interfacial slip in the in-plane direction, the 
      hierarchically LDH-functionalized ramie fabrics (denoted as Textile@LDH) 
      significantly enhanced the mechanical performance of UPR composites. Then, the 
      phosphorus- and silicon-containing coating (PSi) was used for the further 
      improvement of the interfacial adhesion. The tensile strength of 
      UPR/Textile@LDH@PSi composites increased by 121.67%, compared to that of neat 
      UPR. The reinforcement mechanism was studied through analyzing the surface 
      nano/microstructure and wetting properties of the raw and modified textiles, as 
      well as the interfacial interaction between the ramie fabrics and UPR. Meanwhile, 
      the thermal stability, thermal conductivity, and flame-retardant performance of 
      ramie-reinforced UPR composites were improved. Particularly, as-prepared 
      hierarchical Textile@LDH@PSi inhibited the heat release during the combustion 
      process of fabric-reinforced UPR composites, and the peak heat release rate and 
      total heat release values decreased by 36.56 and 47.57%, respectively, compared 
      with the neat UPR/Textile composites. The suppression mechanism was further 
      explored by analyzing the microstructure and chemical compositions of char 
      residues. This research paved a feasible solution to improve the poor dispersion 
      of LDHs in polymers and prepared the high-performance UPR composites with 
      multifunctional applications.
