Summary: In this study, polymer/glass fiber fabric-based nanocomposite plates filled with different filler materials (barite, magnetite, and colemanite) and single-walled carbon nanotubes (SWCNTs) were fabricated. The mechanical properties, thermal conductivity, and radiation shielding properties of the specimens were evaluated. The results showed that the specimens filled with barite and magnetite exhibited adequate mechanical properties, especially in terms of Charpy impact strength. Barite-filled specimens outperformed colemanite and magnetite-filled specimens in terms of mechanical properties. Efficient dispersion techniques could further enhance the mechanical performance of the filler-modified specimens. Additionally, the thermal conductivity and radiation shielding properties of the specimens filled with filler materials were improved compared to specimens without fillers.

Summary: Polypropylene fibers have a significant impact on the mechanical properties of radiation shielding concrete with barite aggregates (RSBC). The addition of polypropylene fibers can significantly improve the compressive strength, splitting tensile strength, and flexural strength of RSBC, enhancing its macroscopic mechanical performance. The mechanical property prediction models of EC 2 and GB 50010 for RSBC exhibit deviations, while the ACI 318 splitting tensile strength model and the flexural strength model established in this research demonstrate good predictive performance.

Summary: In this study, lead-free polymer composite panels with new special formulations were prepared to prevent radiation leakage. By adding a large amount of barium sulfate and polyester resin as a binder, the physical, mechanical, and thermal properties of the composite panels were improved. The panels containing higher percentages of barium sulfate exhibited higher strength and thermal stability, and their attenuation coefficient increased while the HVL and TVL values decreased. These non-toxic composite shielding materials provide a radiation shielding solution for wall panel manufacturing.

Summary: This study examined the impact of different treatments on the low-stress mechanical properties of MDP/C-65/35 fabrics. The use of sericin and glutaraldehyde as a cross-linking agent resulted in higher bending rigidity. However, it was found that the tensile resilience of blend fabrics deteriorated following sericin treatment. Additionally, sericin treatment led to increased shear rigidity and hysteresis. The compression properties of the fabric also suffered deterioration, particularly in harder samples. Surface properties such as friction coefficient and surface contour deviation were generally higher in some cases compared to the control and sericin-treated fabrics.

Summary: The TeO2-CdO-PbO-B2O3 glass system was prepared using the melt quenching method. It was observed that optical packing density, number of bonds per unit volume, and various elastic moduli increased with higher PbO content. Additionally, indirect and direct band gap energies decreased as the concentration of PbO increased. The mass attenuation coefficient derived from EPICS2017 library showed higher values at lower energies compared to Phy-X/PSD, but lower values at higher energies.
