Abstract
In the resin injection pultrusion process (RIP), liquid resin is injected into the tapered injection chamber through the injection slots to completely wetout continuously pulled fibres. As the resin penetrates through the fibres, the resin also pushes the fibres away from the wall towards the centerline, causing compaction of the fibre reinforcements. The fibres are squeezed together due to compaction, making resin penetration more difficult; thus at low resin injection pressures, the resin cannot effectively penetrate through the fibres to achieve complete wetout. However, if the resin injection pressure is too high, the fibres are squeezed together to such an extent that even greater injection pressure is necessary to wetout the compacted fibres. The design of the injection chamber significantly affects the minimum injection pressure required to wetout the fibre reinforcements. A tapered injection chamber is considered such that wetout occurs at lower injection pressures due to the taper angle of the injection chamber. In this study, the effect of fibre pull speed on the fibre reinforcement compaction and complete fibre wetout for a tapered injection chamber is investigated. 16 Refs.
