New Testing Tool For Composite Interfaces

Abstract

Mechanical strength of fiber/matrix interface key factor in overall strength and toughness of composite material. Desktop fiber pushout apparatus generates load and acoustic-emission (soundwave) data as function of translation-table displacement. Video camera gives view of specimen. Compact, easy to operate, and inexpensive. Appropriate for wide range of composites, including metal, intermetallic, and ceramic matrix composites. Not restricted to aerospace/aeronautics applications.
