“…Carbon fibre-reinforced plastics (CFRP) finds extensive application in aerospace, construction, new energy, and marine areas due to its remarkable specific strength and fatigue resistance, making it an attractive alternative to steel [1][2][3][4][5]. However, the friction and wear properties of CFRP also limit its application [6].…”

Solid lubricating coatings were applied onto Carbon Fibre Reinforced Polymer (CFRP) substrates, using epoxy resin as the adhesive agent, graphite (C) and molybdenum disulphide (MoS2) as lubricating components, and alumina (Al 2 O 3 ) as the functional filler. The test parts were prepared by spraying technology and co-curing process. The mechanical properties of the coating were evaluated using Bar hardness and wear rate tests, while the microstructure of the coating was analysed using EDS elemental analysis technology. The test results revealed that the filler content had a significant impact on the mechanical properties. The performance of the coating was determined by the formation of a lubricating film, which resulted from the accumulation of lubricant and reinforcing material during external friction. Scheme T7 yielded the best coating performance with a ratio of epoxy resin to molybdenum disulphide to graphite to alumina of 20:8:3:2.

“…A direct relationship was observed between the delamination factor and the feed rate and cutting speed. Devitte et al [30] present the research results of the influence of cutting speed and cooled compressed air in the drilling of the GFRP/Ti-6Al-4V hybrid stack with an uncoated carbide drill, where GFRP was manufactured by vacuum bag molding. It was found that these two factors influenced the thrust force: an increase in the cutting speed reduced the thrust force by 28%.…”

The aim of the research presented in this paper was to simulate the relationship between selected technological drilling parameters (cutting speed, vc, and feed per tooth, fz) and cutting forces and the delamination in machining of a new glass-fiber-reinforced polymer (GFRP) composite. Four different types of new materials were manufactured with the use of a specially designed pressing device and differed in the fiber type (plain and twill woven materials) and weight fraction (wf) ratio, but they had the same number of layers and the same stacking sequence. A vertical machining center Avia VMC800HS was used for drilling holes with a two-edge carbide diamond coated drill. Measurements of the cutting force Fz in the drilling process conducted with variable technological parameters were carried out on a special test stand, 9257B, from Kistler. The new ink penetration method, involving covering the drilled hole surface with a colored liquid that spreads over the inner surface of the hole showing damage, was used to determine the delamination area. The cause-and-effect relationship between the drilling parameters was simulated with the use of five machine learning (ML) regression models (Linear Regression; Decision Tree Regressor; Decision Tree Regressor with Ada Boost; XGBRF Regressor; Gradient Boosting Regressor). Gradient Boosting Regressor results showed that the feed per tooth had the greatest impact on delamination—the higher the feed was, the greater the delamination became. Push-out delamination factors had higher values for materials that were made of plain woven fibers. The lowest amplitude of the cutting force component Fz was obtained for the lowest tested feed per tooth of 0.04 mm for all tested materials, with the lowest values obtained for the materials with twill fibers.
