“…The density of the composites improved by adding PBO fibers in PEEK due to the higher density of PBO fibers (density of PEEK is 1.32 g/cm 3 and that of PBO is 1.57 g/cm 3 ). However, a difference in density improvement was observed in the cases of Z 50BD (9%) and Z 50 UD (11.5%).…”

“…High-performance polymer composites, especially long fiber-reinforced unidirectional (UD) or fabric-reinforced bidirectional (BD), are well known for their high specific strength, modulus, toughness, and ability to withstand high temperatures. − However, their processing becomes challenging, primarily when the base matrices are polyaryletherketone (PAEK), polyetheretherketone (PEEK), etc. The solution impregnation technique to make prepregs is not applicable for such polymers, since they do not have appropriate solvents.…”

The current research on the development and performance evaluation of unique composites focuses on an unexplored combination of fibers of PBO (polybenzoxazole Zylon) as reinforcement and PEEK (polyetheretherketone) as a matrix. Their fibers were braided in equal ratios and then compression-molded to develop composites by manipulating all long fibers in one direction (unidirectional, a UD composite) and for the other one half in one direction and the remaining half in the perpendicular direction (bidirectional, a BD composite). The performance was evaluated by hardness (micro-and scratch) studies followed by tensile and impact strength. Furthermore, the lap shear strength of the adhesive joints developed with these fibers in various orientations was also analyzed. The performance properties were compared with those of neat PEEK. It was observed that an exceptional increase compared to neat PEEK in impact strength of 10,000% and tensile strength of 662% was achieved in the case of the UD composite. Scanning electron microscopy (SEM) and microcomputed X-ray tomography were used on failed specimens to analyze the reasons for failure.

“…In any case, both composites lie in the range of ESD materials, highlighted in light yellow in Figure 6 a,b. This indicates that both composites can be used in the design of elements of protection for electric devices or staff, or to contain flammable liquids reducing the static electricity in industrial environments [ 43 , 44 ].…”

Many studies assess the suitability of fiber-reinforced polymer composites in additive manufacturing. However, the influence of the fiber length distribution on the mechanical and functional properties of printed parts using these technologies has not been addressed so far. Hence, in this work we compare different composites based on Acrylonitrile Styrene Acrylate (ASA) and carbon fiber (CF) suitable for large format additive manufacturing (LFAM) technologies based on fused granular fabrication (FGF). We study in detail the influence of the CF size on the processing and final properties of these materials. Better reinforcements were achieved with longer CF, reaching Young’s modulus and tensile strength values of 7500 MPa and 75 MPa, respectively, for printed specimens. However, the longer CF also worsened the interlayer adhesion of ASA to a greater extent. The composites also exhibited electrical properties characteristic of electrostatic dissipative (ESD) materials (105–1010 Ω/sq) and low coefficients of thermal expansion below 15 µm/m·°C. These properties are governed by the CF length distribution, so this variable may be used to tune these values. These composites are promising candidates for the design of elements with enhanced mechanical and functional properties for ESD protection elements or molds, so the products can be manufactured on demand.
