“…Over the past decades, carbon-fiber-reinforced polymer (CFRP) composites have shown a constant increase in a variety of applications such as car or aircraft components, sports and medical equipment [ 1 ], and recently also additive manufacturing [ 2 , 3 , 4 ]. Their main benefit lies primarily in the relatively high strength/weight ratio or the ability to customize the material properties for dedicated purposes by changing the stacking sequence and related fiber orientation.…”

The acoustic emission method has been adopted for detection of damage mechanisms in carbon-fiber-reinforced polymer composite tubes during the three-point bending test. The damage evolution process of the individual samples has been monitored using the acoustic emission method, which is one of the non-destructive methods. The obtained data were then subjected to a two-step technique, which combines the unsupervised pattern recognition approach utilizing the short-time frequency spectra with the boundary curve enabling the already clustered data to be additionally filtered. The boundary curve identification has been carried out on the basis of preliminary tensile tests of the carbon fiber sheafs, where, by overlapping the force versus time dependency by the acoustic emission activity versus time dependency, it was possible to identify the boundary which will separate the signals originating from the fiber break from unwanted secondary sources. The application of the presented two-step method resulted in the identification of the failure mechanisms such as matrix cracking, fiber break, decohesion, and debonding. Besides the comparison of the results with already published research papers, the study presents the comprehensive parametric acoustic emission signal analysis of the individual clusters.

Additive manufacturing technology has the potential to bring about significant technological changes to polymer matrix composites. In comparison to traditional manufacturing processes, 3D printing technology is being increasingly utilized in a variety of industries, including aerospace, vehicles, transportation, and medical engineering. The advantages of this technology include low cost, rapid prototyping, and the ability to manufacture complex structures. Nevertheless, the mutual influence and constraints of process parameters in the manufacturing process have led to the fact that the properties of 3D-printed composites have not been able to fully meet the requirements of practical applications. This paper focuses on the current development of the 3D printing process for fiber-reinforced thermoplastic composites. This paper especially reviews the research on the influence of Fused Filament Fabrication (FFF) process parameters (printing temperature, printing speed, ply thickness, and printing path, among others) on the mechanical properties of 3D-printed continuous fiber-reinforced thermoplastic composites. It discusses the problems brought about by the process parameters in the manufacturing process and proposes possible solutions. Finally, it considers the future development prospects and research directions of additive manufacturing of thermoplastic composites.
