Abstract
Deposition of dry fibre (DF) material using automated fibre placement (AFP) and high temperature resin impregnation has emerged as a promising alternative to the use of prepreg for manufacturing high value composite structures, especially for large parts. In this process, the AFP machine deposits a course of multiple dry fibre tapes containing epoxy based binder (5-10 wt. %). The binder is thermally activated to adhere the incoming tapes to the substrate. This work is limited to high temperature vacuum-assisted resin infusion as an out-of-autoclave manufacturing route. Within the aim to enhance industrial implementation of this process, understanding of the interaction between automated dry fibre placement and vacuum-assisted resin infusion requires improvement. In this work, the in-plane permeability variation due to varying spacing and frequency of gaps in preforms deposited by AFP was characterised. In addition, the impact of different infusion set-ups resulting in changes in the balance of through-thickness and in-plane resin permeation, on flow front progression was investigated experimentally. The findings inform material specific manufacturing guidelines for AFP manufacture of an aerospace component.
