Abstract
New experimental set-ups are presented for measuring the pressure profile and fill-times in the Vacuum Infusion (VI) process. In these set-ups, the injection can either be from one of the mould faces (resulting in a rectilinear flow) or from a central port (resulting in a radial flow). From these measurements, the validity of previously reported analytical formulations is investigated. At the start of injection, the experimental results show a marked difference from analytical predictions. However, with flow progression, they change to match with analytical predictions. This phenomenon has not been observed previously and its analysis enhances the current understanding of the process physics, mainly the impact of compliance on the reinforcement thickness and flow progression.
