Fiber reinforced composites are widely used in diverse fields such as aeronautics and automotive. After their shaping, these materials require machining processes to remove excess material and facilitate joining between parts. Due to the heterogeneous nature and anisotropy of these materials, their behavior when being machined is different from metallic ones. Abrasive fibers trigger fast tool wear and delamination appearance can cause piece reprocessing or discard. Delamination is a defect which induces the separation of composite layers and makes the piece present a frayed appearance on the machined edge because the tool bends the fibers instead of cutting them, in addition to producing surface damage to the piece.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
