The article presents the results of a study of the effect of milled and chopped carbon fibers, with an average particle length of 0.2 and , respectively, on the mechanical properties of polyphenylene sulfide and its heat resistance. It was found that the introduction of carbon fibers leads to a significant decrease in the melt flow rate. It was shown that after a sharp decrease in impact strength at 10 % content of carbon fibers, its inverse improvement occurs with an increase in the filler content. Composites containing carbon fibers with length demonstrate higher impact strength. The introduction of a filler leads to a significant increase in the elastic modulus and strength of polyphenylene sulfide and its heat resistance.

“…It is known that the introduction of fibrous fillers significantly increases the polymer melt viscosity [ 26 , 27 ]. When processing by injection molding, this leads to underfilling and defective products, and, when processed by 3D printing (FDM), to poor adhesion of the filaments in the sample and, as a result, to low mechanical properties [ 28 ].…”

The effect of oligophenylene sulfone (OPSU) and polycarbonate (PC) on the rheological, mechanical and thermal properties of polyetherimide (PEI) and a carbon-filled composite based on it was studied. It is shown that the introduction of OPSU and PC leads to a decrease in the melt viscosity of PEI and a carbon-filled composite based on it with the preservation of their mechanical properties and heat resistance at a sufficiently high level. It was found that composites with OPSU have higher mechanical and thermal properties compared with composites with PC. Samples from modified carbon-filled PEI were printed by the fused deposit modeling (FDM) method. Three-dimensionally printed samples from carbon-filled PEI modified by OPSU showed significantly higher mechanical properties than composites with PC.

“…Recently, researches have been developing rapidly in the production and usage field of carbon fibers (CF) and materials based on them, especially after the creation of super-strong (5000-7000 MPa) CF with high ultimate elongations (1.5-2.0 %) and high energy of destruction. The progress in the creation of new binders based on engineering thermoplastic materials with increased heat resistance contributes to the development of carbon plastics [1][2][3][4][5][6][7][8][9][10].…”

In laboratory conditions, the molding process was simulated by extrusion of a multifilament yarn with a diameter of the monofilament equal 250-350 μm from high performance plastics. The possibility of obtaining a microfilament bundle of polyetheretherketone, polyphenylene sulfide and polyetherimide using a specially made forming head is shown. The technological modes of extrusion have been worked out, which makes it possible to obtain thermoplastic fibers from the studied thermoplastics. It was revealed that the obtained microfilaments can be subjected to post-processing by cold drawing to reduce their diameter by 40-70 %.
