Machining of Carbon Fiber Reinforced Plastics/Polymers: A Literature Review

Abstract

Carbon fiber reinforced plastieslpolymers (CERPs) offer excellent mechanical properties that lead to enhanced functionat performance and, in turn, wide apptications in numerous industrial fietds. Post machining of CERPs is an essential procedure that assures that the manufactured components meet their dimensional tolerances, surface quality and other functional requirements, which is currently considered an extremely difficutt process due to the highly nonlinear, inhomogeneous, and abrasive nature of CERPs. In this paper, a comprehensive literature review on machining of CERPs is given with a focus on five main issues including conventionat and unconventional hybrid processes for CERP machining, cutting theories and thermatlmechanical response studies, numerical simulations, tool performance and tooting techniques, and economic impacts of CERP machining. Given the similarities in the experimental and theoretical studies retated to the machining of gtass fiber reinforced polymers (GERPs) and other ERPsparaltet insights are drawn to CERP machining to offer additionat understanding of on-going and promising attempts in CERP machining.

Recent advances in drilling hybrid FRP/Ti composite: A state-of-the-art review

“…However, these factors are not reviewed here individually since the key objective of the paper aims to survey the mechanism issues focused on hybrid composite drilling. Readers are recommended to refer to the mentioned literature [23,24,27,[57][58][59][60][61][62][63]. It should be stressed that in drilling, the changeable fiber breaking type vs. θ, on one hand, is a key contributor to severe hole-wall damage like delamination, fiber pullout, matrix degradation, etc.…”

“…Despite a variety of review papers available on interpreting the machining physics of standard FRPs and single titanium alloys [7,[22][23][24][25][26][27][28][29][30], reviews concerning the multi-physical issues of drilling the two stacked constituents (FRP/Ti) are rarely reported. Recently, Krishnaraj et al [31] has provided a comprehensive review on drilling of multi-material stacks.…”

High performance cutting of advanced aerospace alloys and composite materials

“…For conventional twist drills, a small point angle proved to reduce delamination tendency at hole exit [36,73]. In the last decade, different advanced drill geometries were designed for drilling CFRP.…”

An energy based force prediction method for UD-CFRP orthogonal machining

“…Components made from CFRP are mostly produced by the near-net-shape method, however, secondary manufacturing processes, such as trimming, milling, and drilling, are often required for imparting dimensional tolerance and assembly of composite parts [2]. However, owing to the unique anisotropic characteristics of the material, it is still a challenge to machine CFRP with high-precision surface without delamination, fiber pull-out, or burning [2,3]. Although orthogonal cutting is uncommon in industrial machining processes, the analytical approach of such machining process is essential for better understanding the mechanisms of common processing methods such as drilling, milling, and trimming, etc.…”
