The DGEBA/MDA/GN composite reinforced by common carbon fiber was studied byinvestigating the fracture mechanism on three point bending test. Specimens were made asthe various GN contents and this test was carried out as the various volume fractions ofcarbon fiber. At two fracture surfaces, microstructural factors, that is, pull-out length anddebonded length were measured by Zeiss Projection Microscoping method. From these data,theoretical fracture energy was calculated and then was compared with macroscopic fractureenergy.
