Abstract
Interfacial mechanical properties of carbon/glass hybrid thermoplastic epoxy composite rods play a crucial role in the determination of the composite strength and fracture behavior. In this study, push-out and push-back tests using three hybrid rods with different carbon/glass ratios were performed to investigate the interfacial shear strength and fracture mechanism. Debonding occurred at the interface between the glass fiber bundles and thermoplastic epoxy. After the onset of debonding, sinusoidal behavior during sliding was observed in the load displacement curve, which was identical with the interface roughness in terms of wavelength. Debonding and sliding strength were considered to be related to the interfacial bonding region between the carbon fiber bundle core and surrounding braided glass fiber bundles.
期刊介绍：
The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials.
The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
