Abstract

The mechanical behaviour of carbon fibre reinforced PEEK (APC-2) subjected to different thermal treatments has been studied for sheets of APC-2 prepreg. The prepreg has a distinctive microstructure, as characterized by both DSC and optimal microscopy, which depends on the heat treatment. After heat treatment, the specimens were tested in tension in the 90° direction at 23°C and 160°C, and the fracture behaviour was examined by scanning electron microscopy (SEM). Plastic drawing was always observed before the initiation of cracks in the slow crack growth region. In addition to optical microscopy, the microstructure of the matrix was examined by SEM. The surface morphology of the fractured specimens gives an indication of how the spherulites deform during tensile loading in the 90° direction.
