“This research project is an investigation of the spring back phenomenon associated with manufacturing curved foam core composites. Curved composites are use in many industries, including the automotive and aerospace industry. The curved composite is formed into a curved shape by using a mold. Once the composite is removed from the mold, residual stresses develop in the fabric causing the composite to become less curved. This spring back phenomenon is a problem to most manufactures that are interested in a specific curved shape.
A mathematical model was developed to predict the amount of spring back that occurs in a curved composite panel. Experimental tests were also conducted to observe the behaviors of curved composites upon release from the mold. The results obtained from the experimental tests were compared to the results predicted by the model. The research indicates that the model reasonably predicts the amount of spring back of a curved composite”--Abstract, page iv.
