Abstract:
A dynamic interphase-loading apparatus (DILA) for testing the mechanical properties of an interphase region of a fiber/matrix composite under dynamic loading conditions, the apparatus comprising:means for providing a to dynamic load to the fiber/matrix interphase; means for continuously monitoring the load applied to the fiber/matrix composite and providing a signal representative thereof; means for continuously monitoring the displacement of the interphase of the fiber/matrix composite and providing a signal representative thereof; means for forming various input signals to activate the load providing means and to generate various displacement rates; and a computing means for receiving the load signal from the load monitoring means, for receiving the displacement signal from the displacement monitoring means, and for providing an input signal to the load providing means, the computing means having a memory means connected to a processing means, wherein the processing means stores the load signal in the memory means, generates the input signal supplied to the load providing means, and generates information representing the mechanical properties of the interphase of the fiber/matrix composite.
