| Abstract: | In this paper we investigated the morphology of crazes formed during the fracture process of polymeric fibres. Computed tomography technique was applied to reconstruct the image of fibrils‐voids structure of crazes. This allowed us to investigate the initial stages of crazes formation during the fracture process of mechanically stretched isotactic polypropylene fibres. The density and morphology of crazes were studied at different regions inside the stretched sample. Accordingly, we are able to visualize the internal structure of the stretched fibres in three dimensions. This revealed in‐depth information on the fracture process of polymeric fibres. |
