heal.abstract	In this study AS4 carbon fibers were coated with poly(-hexamethylene adipamide) by two different coating techniques. The glass transition temperature of the interphase was tailored to investigate its influence on the micro-mechanical behavior. The critical length was measured by means of the single-fiber fragmentation test over a wide range of temperatures. Experimental results reveal the sensitivity of the critical aspect ratio of the fiber to the glass transition temperature of the coating and also verify the existence of an epoxy interphase of reduced glass transition temperature near the fiber surface. The effect of the thickness of the coating on the critical aspect ratio of the fiber was also investigated. An increase in the thickness of the polyamide coating results in poorer adhesion.In this study AS4 carbon fibers were coated with poly(hexamethylene adipamide) by two different coating techniques.
