**Abstract**
 In the resin injection pultrusion process (RIP), the liquid resin is injected into the continuously pulled fibres through the injection slots to cause complete wetout of the fibres. As the resin penetrates through the fibres, the resin also pushes the fibres away from the wall causing compaction of the fibre reinforcements. When the fibres are squeezed together due to compaction, the resin penetration becomes more difficult; thus a resin injection pressure below a certain pressure cannot effectively penetrate through the fibres and achieve complete wetout. However, if the resin injection pressure is too high, the fibres are squeezed together to such an extent that the fibre becomes essentially impenetrable by the liquid resin. The harder it is to penetrate through the fibres, greater is the tendency of the fibres to be pushed away from the wall and cause compaction and affect wetout. In this study, the effect of fibre volume fraction on the fibre reinforcement compaction and the complete wetout is presented. 14 Refs.
