Abstract
A method for the reuse of PEKK-based carbon fiber reinforced polymer composites is provided. Chips obtained by comminuting the carbon fiber-reinforced PEKK composite material are melt mixed with a virgin poly(aryletherketone) polymer to provide carbon fiber-reinforced poly(aryletherketone) compositions. Molded articles having good mechanical properties can be prepared from the carbon fiber-reinforced poly(aryletherketone) compositions.
Claims18
A method for making a carbon fiber reinforced poly(aryletherketone) composition said method comprising:
- providing chips of CF/PEKK composite material;
- and
- melt mixing said chips with at least one poly(aryletherketone) polymer different from the PEKK in the CF/PEKK composite material, wherein the CF/PEKK composite material comprises a unidirectional continuous fiber reinforced tape made by a melt impregnation process or a slurry process.
