초록
In this paper the influence of fiber orientation of basalt and carbon inter-ply fabrics on the flexuralproperties of hybrid composite laminates was experimentally investigated. Four types of basalt/carbon/epoxy inter-plyhybrid composite laminates with varying angle ply orientation of reinforced basalt fiber and fixed orientation ofcarbon fiber were fabricated using hand lay-up technique. Three point bending test was performed according toASTM 7264. The fracture surface analysis was carried out by scanning electron microscope (SEM). The resultsobtained from the four laminates were compared. Lay-up pattern of [0B/+30B/-30B/0C]S exhibits the best propertiesin terms of flexural strength and flexural modulus. Scanning electron microscopy results on the fracture surfaceshowed that the interfacial de-bonding between the fibers and epoxy resin is a dominant fracture mode for all fiberlay-up schemes.
