Modeling and optimization of interlaminar bond strength for composite tape winding process

The prepreg tape winding product of thermoset composite has been widely used in aerospace industry due to the favorable performance. The manufacturing process is the key to ensure the quality of product. This study is focused on the theoretical analysis of prepreg tape winding process. The mathematical model of thermal and consolidation process is established firstly. The influence mechanism of the major process parameters including heating temperature, consolidation force and winding velocity on consolidation quality is subsequently studied based on the simulation results. And the tape winding experiments and interlaminar shear strength tests are conducted to validate the predictive capability of the theoretical model. Moreover, the coupling role between the process parameters is explained based on the predicted model. In order to control the quality of winding product, the optimization of winding process is proposed, and the three-dimension process window of parameter settings is obtained.
