Fiber Reinforcement Compaction In Resin Injection Pultrusion Process, Neerad Shakya

Electronic Theses and Dissertations

Resin injection pultrusion is a cost-effective continuous manufacturing process to produce composites of constant cross-section. In this process, fiber reinforcements are continuously pulled through the injection chamber where liquid resin is injected to cause complete wetout of the fibers before exit. The fiber-resin combination obtained from the injection chamber is then cured to obtain the desired pultruded composite. There are various processing and geometric parameters affecting the wetout process. The main objective of this study is to present a numerical model to simulate the resin flow through the fiber reinforcement when compaction of the fibers is also taken into account. …
