In this study, carbon fiber Z-pins were fabricated by applying the different manufacturing process, and pull out test was performed for the dumbbell type of test specimens. Carbon fiber Z pins with smooth surface(type I) and stepped surface(type II, type III) were fabricated by using autoclave. Carbon fiber Z-pins with stepped surface were manufacturing method, that is, mold forming and machining process. The experimantal results show that carbon fiber Z pins have superior pull-out characteristics to carbon steel Z-pins. Pull-out load and pull-out toughness of carbon fiber Z pins with stepped surface are larger than those of carbon fiber Z-pins with smooth surface. Pull-out load and pull out toughness of mold f ormed Z-pin are 31% and 218% larger than those of smooth surfaced Z-pins, respectively.
