“…The ratio of I D / I G of the transfer film formed at 0.2 m s −1 was found to be 1.80, which indicated that the strong shear stress caused by adhesion may promote graphitization of the transfer film. However, further increase of the sliding speed suppressed the graphitization degree of the corresponding transfer films due to the reduction of interfacial shear strength 46 . Compared with the transfer film at 1 m s −1 , the friction‐induced higher interfacial temperature may lead to a decreased I D / I G value of the transfer film established at higher sliding speeds 44 …”

Carbon fiber reinforced polyether ether ketone (CF/PEEK) composites are widely used as tribo‐materials in aerospace and automotive industry. To amplify the industrial utilization of extrusion‐based additive manufacturing fused deposition modeling (FDM) in fabricating CF/PEEK tribo‐composites, the composites' microstructure‐property relationship was studied with respect to carbon fiber content varied between 5 wt% and 30 wt%. It was revealed the incorporation of carbon fibers helped enhance the mechanical strength of PEEK greatly with an optimal content of 5 wt%, at which the composite material exhibited the highest crystallinity as well as the best mechanical performance. Tribological tests indicated that CF/PEEK composites were more suitable for high speed and heavy load conditions especially for 20 wt% CF/PEEK, which was associated with the establishment of high quality transfer films covered on counter steel surfaces. The present work provides a simple and low cost way of fabricating high performance PEEK composites used as tribo‐materials.This article is protected by copyright. All rights reserved.

“…These kinds of composites optimized by different materials are widely used in aerospace, automotive, and marine fields due to their excellent properties. [8][9][10][11] According to the type of reinforcing phase, composites are divided into particle reinforced composites, 12,13 short fiber reinforced composites, 14,15 and continuous fiber reinforced (CFR) composites. [16][17][18][19][20] Among them, CFR composites, in particular, have been extensively studied for their superior mechanical properties.…”

Inspired by the exceptional strength and toughness of fresh bamboo, a low‐cost method for preparing continuous fiber‐reinforced multi‐matrix composites based on 3D printing was proposed in this paper. Through the design of a special extrusion nozzle, the controllable feed of polylactic‐acid (PLA) and thermoplastic polyurethane (TPU) filaments was achieved, allowing for the preparation of continuous carbon fiber reinforced PLA/TPU composites. The effects of various process parameters on the tensile and flexural properties of the CCFR‐PLA/TPU composites were investigated. Additionally, the relationship between process parameters and the formation of the matrix‐fiber interface and PLA‐TPU interface was analyzed. The results show that layer height has the greatest influence on mechanical properties, while the printing speed has the least influence. The mechanical properties of the CCFR‐PLA/TPU composites and the unreinforced blend matrix, prepared using the optimal combination of process parameters, were tested. The results demonstrated that the tensile strength and flexural strength of the CCFR‐PLA/TPU composites increased by 16.95 and 1.80 times, respectively, compared to the unreinforced blend matrix. Further, inspired by the overall structure of bamboo, a stiffness gradient CCFR composite material was designed and prepared. The methodology employed in this study holds significant implications for the advancement of novel multi‐matrix hybrid continuous fiber reinforced composites, particularly in aerospace and related industries.Highlights Multi‐matrix continuous fiber reinforced composites were prepared by 3D printing inspired by fresh bamboo. The effects of process parameters (nozzle temperature, printing speed, extrusion width, layer height) on mechanical properties were investigated. The optimal printing parameter combination was determined by range analysis. Stiffness gradient composites were prepared inspired by the overall structure of bamboo.
