Sébileau and co‐workers developed fully dense Poly(ether ether ketone) (PEEK) bulk by a non‐conventional approach: Powder Metallurgy route. The original processing, based on Spark Plasma Sintering, allows consolidating high‐performance thermoplastic polymers at temperatures below the melting point. Thanks to this particularity, the degree of crystallinity in the sintered PEEK remains quite close to the native powder one. As a consequence the mechanical properties obtained for sintered PEEK are found to be comparable to those of commercial materials. The cover image, obtained by scanning electron microscopy, exhibits the microstructure of sintered PEEK in which particles from native powder are still available. (DOI: 10.1002/app.44911 )
