OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 27 No. 1 2025 а b c Fig. 10. SEM images for 10 wt. % PEEK in Acrylate material at different magnification: а – 500× magnification, 50 µm; b – 2,000× magnification, 10 µm; c – 5,000× magnification, 5 µm At 500× magnification, the material’s surface exhibited a relatively smooth texture, comparable to materials containing a lower concentration of PEEK. However, the higher PEEK concentration led to more pronounced differences in the texture, indicating a significant influence of the PEEK particles on the surface composition. The observed changes were subtle but consistent, suggesting a uniform distribution of PEEK within the matrix (Fig. 10, b). Increasing the magnification to 2000× made the PEEK particles more visibile. They were observed as discrete inclusions within the polymer matrix, with a size of approximately 1–2 μm. The distribution pattern indicates good integration of PEEK into the base material, promoting enhanced structural homogeneity and, consequently, improved mechanical properties of the composite. At 5,000× magnification (Fig. 10, c), the SEM images provided more detailed information about the microstructural features, confirming the uniform distribution of PEEK particles and the absence of aggregation. The surface maintained an amorphous structure, with the presence of PEEK contributing to minor variations in texture that did not disrupt the overall smoothness of the material. This homogeneous component distribution is critical for achieving an optimal balance of flexibility and strength, which is necessary for the intended application of this material. EDS Analysis and elemental composition EDS analysis provided precise and quantitative data regarding the elemental composition of the 10 wt. % PEEK material. The primary elements identified were carbon (C) and oxygen (O), consistent with the composition of PEEK and the base polymer (Fig. 11). Table 4 presents the elemental composition of 10 wt. % PEEK in Acrylate. The substance in a specific area consisted of approximately 70.19 wt. % carbon and 29.81 wt. % oxygen.
