“…After gamma spectrometric measurements linear (l L ) and mass (l M ) attenuation coefficients and half value layers (HVL) were calculated for the composites and also pure lead (the most widely used shielding material) for comparison. The details of the shielding performance measuring and calculation procedure were already reported [7]. …”

“…Thus mineral-polymer composites and their shielding properties at different IEMR energy regions have not been exploited so far. In view of this, natural hematite filled composites were investigated for IEMR shielding applications in our previous study and challenging results were reported [7]. In the present study, a novel light weight and non toxic composite IEMR shielding material with relatively high IEMR shielding performance prepared and characterized.…”

“…Generally heavy filler materials are used with polymer matrixes like metals and metal oxides [1,2,4]. There are also numerous studies in which several natural minerals are used as filler materials for the composite IEMR shielding like serpentine, hematite and limonite [5][6][7]. A comprehensive literature review revealed that the potential IEMR shielding properties of natural mineral filled composites were investigated only with cement matrixes.…”

In the study, usability of natural titanium-iron oxide filler for ionizing electromagnetic radiation (IEMR) shielding composites with isophthalic polyester (PES) matrix was investigated for the first time. Shielding performances of the composites were also investigated for three different IEMR energy regions as low, intermediate and high for the first time, too. Mass attenuation coefficient of prepared composite with the best shielding performance reached 80 % of elemental lead's performance at low energy regions while it had higher mass attenuation coefficient at intermediate and high energies.

In the present study, new fiber‐metal laminates (FMLs) are manufactured from the lay‐up process of the carbon fibers‐tungsten carbide nanoparticles/phthalonitrile (CFs‐WC/PN) composite and the Al–Li alloy. The properties of the developed hybrids are analyzed and compared with those of the monolithic alloy. Generally speaking, the results indicate that the amount of the fiber considerably affects the tensile properties. The mechanical properties of the FMLs show enhancements over both the Al–Li alloy and the CFs/PN composite individually. When the number of the composite layers varies from 4 to 12, the ultimate tensile strength of the prepared FMLs increase from 335.3 to 690.5 MPa. The FMLs present a ductile behavior (up to a failure strain of 20%), which can be attributed to the ductile fracture morphology of the Al–Li alloy. These improvements are the result of the synergistic combination of the high strength of composites and the superior ductility of metals. In the meantime, the gamma rays (γ‐rays) shielding test reveals that increasing the weight amount of the tungsten carbide (WC) nanoparticles in the composite noticeably improves the screening ratio, reaching the exceptional value of 46% for the hybrid containing 20 wt% of WC.
