Abstract
This work studies the effect of compaction of tapes that have been heated using a laser during automated fibre placement. The deconsolidation has been shown to have a significant effect on the surface roughness, degree of effective intimate contact and void content. This work investigates whether after compaction the as-received (i.e., before heating) properties are obtained, or whether the deconsolidationcompaction cycle has an influence on the final tape quality. First, a lab test set-up is designed and manufactured to mimic the real manufacturing conditions. Next, the set-up is used to study the influence of the placement speed and pressure on the final quality. The results show that the effects of deconsolidation are mostly reversed, but the final tape still has slightly worse qualities. This effect will have to be taken into account for accurate modelling of the laser-assisted automated fibre placement process.
