Abstract:Carbon fiber (CF)‐reinforced polymers (CFRPs) demonstrate potential for use in personal protective equipment. However, existing CFRPs are typically rigid, nonrecyclable, and lack of tearing resistance. In this study, flexible, recyclable, and tearing resistant polyurethane (PU)‐CF composites are fabricated through complexation of reversibly cross‐linked PU elastomer binders with CF fabrics. The PU‐CF composites possess a high strength of 767 MPa and a record‐high fracture energy of 2012 kJ m−2. The high perfor… Show more
