Abstract
Carbon-reinforced polyether ether ketone or C-PEEK has many uses in engineering applications. Fused Deposition Modeling (FDM) is the additive manufacturing method of choice for producing C-PEEK components because of its low cost and high efficiency. Anisotropy is commonly associated with such components because of the raster angle between the printing and loading directions. However, the impact of raster angle on the local state of strain has received comparatively less focus. The present work attempts to fill this research gap using Digital Image Correlation (DIC) to measure full-field deformation of C-PEEK. Standard specimens are tested for failure by fracture at 0°, 45°, and 90° raster angles. The strength is the highest at 0° raster angle, whereas it is the lowest at 90° raster angle. Brittle fracture is the cause of failure for all samples. The most important part of the failure mechanism is played by strain localization that develops near the interfaces between adjacent beads or layers.
