SOM/SEM based Characterization of Internal Delaminations of CFRP Samples Machined by AWJM

Linear Abrasive WaterJet Machining (AWJM) tests have been performed on Carbon Fiber Reinforced Plastic (CFRP) in order to have a first reference of the main defects developed onto the machined surface.Delamination has been proved as one of the most critical defects when machining composites or layered materials. In this work this defect and the influence of cutting parameters in its formation have been studied. For this purpose, delamination morphology has been characterized using Scanning Optical Microscope and Scanning Electron Microscope. Additionally, a study of the influence of cutting conditions and material removal mechanisms involved has been achieved.
