Abstract
Resin-injection pultrusion (RIP) processes rely on high resin pressure for efficient impregnation. This study investigates the effects of flow-induced fiber compaction in RIP, considering temperature measurements and material characterization. Governing equations are derived, and a novel numerical framework is presented. The analysis reveals that fiber compaction reduces flow resistance, facilitating resin impregnation. In the case study, fiber compaction near the inlet resulted in upstream movement of the flow front and increased exit pressure. Furthermore, impregnation occurred over a longer distance due to increased fiber volume fraction at the profile center. The compaction response of the fiber material
remained largely independent of injection pressure magnitude. This research contributes to understanding material behavior and improving RIP processes.
