Fiber‐Matrix Interphase In article 2305642, Christopher C. Bowland and co‐workers introduce a hierarchically architected fiber‐matrix interphase for a tougher composite. High aspect ratio chemically transformable thermoplastic nanofibers, integrated at the interphase, form covalent bonds with the matrix through heat treatment, enhancing composite toughness. This scalable approach offers a chemically less intensive solution to address persistent weak interphase issues in the composite industry. [Image: see text]
