Abstract

The XeCl laser ablation of a polyetheretherketone (PEEK)-carbon fiber composite (APC-2) is reported. Etch rates and measurements of the ablation products have been carried out, together with scanning electron microscope evaluation of the etch craters. Selective removal of the PEEK matrix occurs for fluences ∼70–400 mJ cm−2. Net composite etching commences at ∼420 mJ cm−2, with an etch rate above this value that is determined by the carbon fibers and is consistent with thermal vaporization at high temperature (≥4000 K).
