New Technique for Determining Mechanical Property of Polymer/Metal Interface

摘要

A new experimental technique for determining mechanical properties of the polymer-metal interface was developed by replacing conventional mechanical testing machine with a piezoelectric actuator. Using this technique, fatigue crack growth behavior of epoxy/aluminum interface was studied as a function of electric field, crack length and cyclic frequency. The crack growth rate was found to depend on the magnitude of the applied electric field and decrease with testing frequency.
