Prediction of Dimensional Changes in Composite Laminates During Cure
34th International SAMPE Symposium and Exhibition, May 8-11, 1989, R. H. Nelson, D. S. Cairns. Ron is effectively, the founder of this academic and applied scientific field, commonly referred to as “Springback” analysis. Ron formulated the scientific, analytical, and experimental approaches used today in his 1989 technical Sampe paper “Prediction of Dimensional Changes in Composite Laminates during Cure”. Analytical techniques for predicting dimensional changes in composite structures during cure are presented. Musical techniques can be used to predict the tool Dimensions needed to produce a composite structure of a given dimensions. Empirical observations and analytical studies of Tool Part interactions occurring during the Cure of thermoset Composites have led to the development of the relatively simple techniques presented in this paper. The need for a scientific and systematic study of tool composite part interaction during cure is emphasized is extremely accurate predictions of final part dimensions and residual stresses are required. What types of processing related dimensional changes are presented with descriptions of their come on causes an analytical prediction approaches. Investigation of the causes and analytical techniques for predicting annual spring back and composite laminates was conducted and is presented.
