Effect of Thermal Input on the Temperature Distribution of Thermoplastic Composites Made by Automated Fiber Placement (AFP)



The heat transfer analysis of thermoplastic composite manufactured using automated fiber placement with a hot gas torch can be done using numerical methods such as finite difference method. The accuracy of the theoretical results depends upon the accuracy of the thermal inputs. The hot gas/air temperature and convection coefficient distributions between the hot gas and the surface of the substrate (thermal inputs) have the significant influence on the accuracy of the resulting theoretical temperature distributions in the deposited laminate. A model predicting theoretical results which agree with experimental measurements is presented
