Robust Manufacturing of Composite Parts: Analysis of Spring-in Shape Distortions
Abstract: The present thesis investigates the development of shape distortion in mass produced composite components. More specifically the spring-in of corners manufactured using Resin Transfer Moulding, RTM was studied. The investigation was performed experimentally after theoretically ruling out several possible factors and parameters. A series of L-shaped brackets were manufactured and the influence of thickness and corner radius was assessed. Partly in contradiction to some previously published studies, the presented results suggest that spring-in of L-brackets produced using RTM, during fully geometrically constrained conditions and isothermal cure, are influenced by both thickness and corner radius.
