A Model for Nonisothermal Healing of Thermoplastic Polymers During Fusion Bonding


 Polymer healing, referring to the intermolecular diffusion across the interfaces of thermoplastic tape layers in intimate contact, is one of the important steps in fusion bonding responsible for the development of interlaminar bond strength, and is strongly influenced by the temperature history. In this paper, a model for the healing process under non-isothermal conditions is developed starting from a fundamental formulation of the reptation of polymer chains. Considering the temperature dependence of the reptation time, the bond strength is described as a function of temperature history. Parametric studies and comparison of the model with available models in the literature are presented.
