Carbon fiber composite materials generate great interest in industry. This is due to their excellent mechanical properties and their lightweightness compared to heavy metals such as steel or titanium. In addition, the degree of utilization and recyclability of this type of materials has increased in the last decade. However, the nature and anisotropy of these materials can lead to defects after machining. One of the most influential parameters in the machining of composite materials is the temperature generated during the process. Abrasive water jet machining (AWJM) allows composites to be machined by greatly reducing the temperature caused. However, this nonconventional machining involves a variety of defects, which must be taken into account in order to optimize the final part obtained. This book chapter develops a contextualization of machining of polymer matrix composite materials by abrasive water jet process. For this purpose, an introduction on this type of materials and their components has been given. In addition, a concise introduction of the input parameters that influence AWJM has been reported. The defects caused during the process have been described from different points of view: functional, geometric, and cosmetic defects. A literature review has been carried out to analyze the influence of these defects. Finally, a set of conclusions has been developed to summarize the overall discussion conducted throughout the manuscript. |
