In this presentation, the effects of carbon fiber reinforcement on the structure and mechanical properties of AM parts will be discussed. Upper bounds for tensile properties of AM carbon fiber composites are theoretically evaluated and compared with the experimentally measured values. From a structural standpoint, additive manufacturing allows for the implementation of specially designed fiber placement within the parts; the fiber orientation will follow the defined nozzle path during the AM process. With a knowledge of the loading profile and failure mechanics of AM composites, parts with unprecedented performance and weight can be designed and manufactured. In this regard, an outlook for the design optimization of AM fiber reinforced parts will be presented. This presentation will also cover post-processing of high-value composites to remove internal porosity and reports their processing-structure-property relationships across length scales. Hot isostatic pressing (HIP) of carbon fiber reinforced thermoplastics to improve their flexural, interlaminar, tensile, and compressive properties will be discussed in detail.
