Abstract
This study was designed to analyze the loadcarrying capacities of composite structures connected facetoface by a butterfly coupling component experimentally and numerically without adhesive The results of the experimental studies were supported with numerical analysis In addition the butterfly coupling component was developed geometrically with a view to the results of the numerical and experimental studies The change in the loadcarrying capacity of the improved butterfly coupling components was analyzed numerically and experimentally to obtain new results Halfspecimens and butterflyshaped lock components were cut with a water jet machine Experiments and analyses were conducted to analyze the effects of coupling geometry parameters such as the ratio of the butterfly end width to the specimen width w/b the ratio of the butterfly middle width to the butterfly end width x/w and the ratio of the butterfly half height to the specimen width y/b It was intended to determine the damage in the butterfly before any damage to the composite structure and to increase the servicelife span of the composite structure with the repair of the butterfly lock As a result of this study it was determined that the geometrical fixed ratios w/b and x/w were 04 and 02 at 04 of y/b according to the experimental and numerical studies with basic and modified modelsGürkan Altan is a Research Assistant of Mechanical Engineering at the University of Pamukkale Denizli Turkey Gürkan Altan received his BE degree in Mechanical Engineering from Dokuz Eylül University Izmir in 1999 He received his MS and PhD degrees in Mechanical Engineering from Pamukkale University Denizli in 2004 and 2009 respectively Dr Altan is interested in the production and applications of composite materials He is currently involved in the development and application of joints of composite structures
