Study on the Improvement of Inter-laminar Bonding Strength of Carbon/Epoxy Composite Structures

Carbon/Epoxy 복합재료 구조물의 층간강도 향상 연구

In these days, composite materials are applied to the military field like parts of air crafts, rockets, ammunitions and so on. As high pressure is loaded on the composite body, however, cracks or delamination phenomena can be occurred between layers of laminate. These cracks or delamination usually cause a deterioration of mechanical properties under the complicated loads. In this study, methods for improvement of the inter-laminar bonding strength of thick carbon/epoxy composite structures are suggested and discussed in terms of segment bending test.
