Oxidation behavior of PEKK matrix

, 2019
The IMPEKKABLE project deals with the use of organic matrix composite materials such as thermoplastic matrix reinforced with continuous carbon fibers for “high temperature” parts. More precisely, it refers to the utilization of a new generation of C/PEKK composite for structural applications around 180°C above the glass transition of the thermoplastic ...
