Abstract
Poly(ether ketone ketone) (PEKK) composites include reinforcing fibers in a PEKK polymer matrix that includes a PEKK polymer. It was surprisingly discovered that by washing unneutralized PEKK polymer powder with an acid or base, the melt stability of the PEKK polymers can be improved, as compared with PEKK polymers prepared by conventional methods. The PEKK composites are especially well-suited for fabrication of thick composite parts where melt stability is especially important.
