WebPolyaryletherketone. Polyaryletherketone ( PAEK) is a family of semi-crystalline thermoplastics with high- temperature stability and high mechanical strength whose molecular backbone contains alternately ketone (R-CO-R) and ether groups (R-O-R). The linking group R between the functional groups consists of a 1,4-substituted aryl group. WebAbstract. The laser-assisted thermoplastic tape placement process for unidirectional carbon fiber reinforced polyetheretherketon (CF PEEK) tapes was investigated. In this process, tapes are melted, laid-up on a tool, and consolidated under a roller. As an out of autoclave process, thermoplastic tape placement has high potential for aerospace ...
