Abstract In order to distinguish the grinding performance of thermoset and thermoplastic carbon fiber‐reinforced plastic (CFRP) composites, epoxy resin (CF/epoxy) poly‐ether‐ether‐ketone (CF/PEEK) composites were employed in this study. Different process parameters set grind two materials. Then surface morphologies roughness workpieces with different observed measured. Experimental results indicated that forces positively correlated depth feed speed, negatively wheel speed. The was main influencing factor maximum temperature grinding. heat distribution dependent on fiber direction. addition, chip formation mechanism CF/epoxy CF/PEEK investigated. Compared CF/epoxy, higher more prone be clogged under same parameters, indicating it difficult CF/PEEK. However, quality high ductility much better than CF/epoxy.

Abstract To distinguish the grinding performance of multidirectional (MD) and unidirectional (UD) carbon fiber‐reinforced thermoplastic (CFRTP) composites, MD UD poly‐etherether‐ketone (CF/PEEK) composites were employed in this study. Different ply stacking sequences process parameters set for experiments. Subsequently, surface morphologies roughness observed measured. Experimental results indicated that variations forces with MD‐CF/PEEK UD‐CF/PEEK consistent. However, heat transfer mechanism effects on maximum temperatures different between two composites. The slightly lower than UD‐CF/PEEK, reached better quality under same parameters, indicating was not simple superposition UD‐CF/PEEK. In addition, chip formation material removal CF/PEEK investigated. primarily dependent θ elements laminate while closely related to fiber orientation angles during grinding. This study established a more in‐depth understanding into provided technical guidance high‐quality CFRTP. Highlights is compared. are reach parameters. laminate, change layering order critical factor. process. MD‐CFRTP can be effectively improved by reducing depth feed speed, increasing wheel speed.
