Abstract

Intimate contact development has been considered as one of the principal mechanisms for consolidation during the automated fiber placement process. This work aims to investigate the effect of process parameters of LAFP on intimate contact development. Effects of nip point temperature, tool temperature, compaction pressure and placement speed on intimate contact development is experimentally investigated. 1-layer, unidirectional strips of CF/PEKK material are placed with different process parameters on a flat tool surface. Based on the observations, the concept of effective intimate contact is introduced and used to assess the degree of intimate contact. The results suggest that the effect of compaction pressure is linear whereas the effects of the placement speed is nonlinear.
