“…Although many CFRTP parts can be manufactured into near-net-shape [8,9], riveting through assembly holes is still indispensable for rapid assembly of load bearing parts [10] and precise positioning of aircraft components [11]. To date, literature on hole making of the well-established conventional thermoset CF/epoxy composites is widely available [12][13][14]. Unfortunately, relevant reports on CFRTP, particularly their machining induced damages and the associated material removal mechanisms, remain scarce.…”

Although new generation carbon fibre reinforced thermoplastic (CFRTP) such as carbon fibre reinforced polyetherketoneketone (CF/PEKK) is a promising sustainable alternative to the conventional thermoset CFRP, there is a lack of literature regarding its machining performance. This is the first study unveiling the hole wall and chip temperature evolution during drilling of thermoplastic CF/PEKK composite and the resulting material damages have been studied in detail. Through comparative study with CF/epoxy, the disparate drilling performance of the two composites has been uncovered, and the results were found to be closely related to the materials’ thermal/mechanical properties. Specifically, CF/PEKK produces continuous chips due to its excellent ductility and thermal sensitivity, whereas CF/epoxy produces segmented chips due to its brittle nature. CF/PEKK generates up to 40 N (50.5%) higher thrust force, 87.6 ℃ (98.9%) higher hole wall temperature and 61.1 ℃ (48.8 %) higher chip temperature than that of CF/epoxy. This has been correlated to the longer tool-chip contact length of CF/PEKK and its unique chip morphology. Despite the greater thrust force/temperature generation, CF/PEKK shows 55.7% lower delamination damage than CF/epoxy, and this is owning to its excellent interlaminar toughness. This study establishes a more in-depth understanding into the drilling performance of thermoplastic CF/PEKK and thermoset CF/epoxy and also provides guidance on the high performance manufacturing of next generation CFRPs.

“…Coal is prominent in China's energy, the huge demand has promoted the rapid development of modern mining machinery. However, the working conditions of mining machinery are extremely harsh, resulting in more serious wear and tear of its mechanical parts, thus greatly reducing the service life of the parts 1 . Therefore, in the production process, have to stop often for maintenance, replacement parts, and even major accidents can occur due to parts wear, the development of mining machinery has caused a major obstacle.…”

The severe working conditions of mining machinery make the wear of its parts extremely serious, thus reducing its service life, increasing the probability of accidents, and may cause huge economic wastage. So promoting the improvement of mining machinery is imperative, and the melting of wear‐resistant layer on the surface of wear‐prone equipment is a more effective improvement method. The study was performed by laser fusing a composite coating of CoCrFeNiMn high‐entropy alloy with different WC contents, and a second phase was generated in the coating by an additive method to achieve the strengthening of the coating. The experiments revealed that all the coatings had FCC phase as the main phase by analyzing the phase conformation, structure, stiffness, and abrasiveness. When the WC dosage exceeded 20 wt.%, Fe3W3 (M6C) carbide reinforced phases with different morphologies were produced in the coatings. Forty wt.% of the coatings showed the highest hardness, which was 3.1 times better than that of the coatings without WC particles, and 30 wt.% of the coatings showed the best abrasiveness. HT0 coatings showed the least friction factor of 0.27. HT600 and HT800 corresponded to friction factors of 0.37 and 0.35, respectively. The coefficient of friction of the coating was most stable after about 3 min at room temperature, and the wear phase took longer after annealing. During the break‐in phase, the precipitated phase has a supportive effect and prolongs the break‐in period. The coating using the studied method improves the wear resistance of mechanical parts and extends their service life, which has some economic and practical value.

Fibre reinforced thermoplastic polymer (FRTP) composites have been used for a wide range of engineering applications (e.g. in transport, construction, energy, etc) due to their excellent mechanical properties and ease of repair and recycling. In recent years, FRTP is increasingly deployed as an alternative to conventional thermoset carbon fibre reinforced epoxy (CF/epoxy) composites, for the purpose of reducing the carbon footprint and contributing to a sustainable manufacturing agenda. Machining of FRTP remains an indispensable process to achieve rapid parts assembly whilst meeting stringent geometric tolerances. However, due to the heterogeneous structure and high thermal sensitivity of FRTP, a range of machining-induced damages (such as matrix smearing, thermal degradation, delamination, burr and surface cavity) often occur, leading to concerns on machined parts quality and reliability. To date, composite machining studies have been mostly focused on conventional thermoset CF/epoxy and there is a lack of an up-to-date, in-depth review of the latest advancement concerning the machining of FRTP. This paper provides a state-of-the-art overview on the recent developments in FRTP machining over the past decade, with a particular emphasis on machining characteristics, damage mechanisms as well as the challenges facing such manufacturing process. The purpose is to present the composite manufacturing community with a timely update, which may guide and inspire further research and development for future FRTP manufacturing.
