This paper presents a methodology for designing hard compaction rollers for an automated fiber placement (AFP) head with a hot gas torch heating system for laying thermoplastic carbon fiber reinforced plastic (CFRP) tapes. Some manufacturing defects and alternative designs are reviewed to highlight the importance of AFP compaction roller conformity and surface adhesion. The formulation of a general parametric description of the design challenge is derived and adequately addresses the problem on a tow-to-tow basis.
