Abstract :
Polyether ether ketone (PEEK) is one of the thermoplastic materials with high performance with regard to thermal and chemical stability, which is expected to replace metallic materials in industrial fields. In this paper, the demonstration of PEEK ablation by a TEA C0 2 laser is reported and PEEK ablation at a high fluence (>10 J/cm2) is discussed in terms of fluence dependence of the etch rate and ambient gas effect
