The　fiber-reinforced　polymer　(FRP)　composites　have　been　widely　used　as　bullet-proof　materials　due　to　their　low　specific　gravity,　high　specific　strength　and　stiffness,　and　excellent　impact　resistance.　A　comprehensive　understanding　of　the　energy　absorption　of　the　FRP　composites　during　impact　and　penetration　and　accurate　prediction　of　the　ballistic　limits　of　the　FRP　composites　may　provide　valuable　guidance　for　designing　bullet-proof　composites.　In　this　review　paper,　various　analytical　and　numerical　research　on　the　ballistic　limits　of　FRP　composites　are　outlined.　Besides,　the　influences　of　various　factors　such　as　component　properties　and　microstructure　of　FRP　composites　and　impactor　characteristics　on　the　ballistic　limits　of　FRP　composites　are　discussed.　We　focus　on　introducing　new　methods　and　ideas　that　provide　guidance　for　the　design　of　advanced　bullet-proof　composites.　©　2024　Elsevier　Ltd
