“…As calculations involve more details concerning the attenuation of gamma rays, a comparison between simulating mass attenuation coefficient and experimental mass attenuation coefficient was conducted. The calculation was performed by the XCOM computer software, which was developed by NIST . Calculation of mass attenuation coefficient [( μ/ρ ) theo , cm 2 g −1 ] in this software is based on the mixture rule:

{(\frac{μ}{ρ})}_{t h e o} = \sum ω_{i} {(\frac{μ}{ρ})}_{i}

where ω i and (μ/ρ) i are weight fractions and mass attenuation coefficients of the constituent elements i , respectively.…”

“…Moreover, the existence of high Z chemical elements, such as Ti, Fe, Ba, Mn, makes BF have better radiation shielding ability compared with carbon and glass fibers. However, due to the limited shielding ability of the original BF composite , functional particles are in need to modify BFRPs for enhancing shielding property. Previously, we fabricated BF reinforced epoxy composite filled with Er 2 O 3 particles .…”

Continuous basalt fiber (BF) reinforced epoxy matrix composites with different contents of micro‐tungsten powder were fabricated by hot‐press process with prospective of combined radiation shielding and mechanical functions. Gamma photon shielding and mechanical properties of the composites were evaluated. The measured mass attenuation coefficient shows that tungsten filler significantly improves the radiation shielding property of BF composite, especially for low and moderate photon energies of 80 and 356 keV. Flexural strength of BF composite decreases along with increasing tungsten concentration, while flexural modulus and interlaminar shear strength are not obviously affected by tungsten content. Given the advantages of lightweight, high mechanical property and good radiation shielding performance, the studied BF/tungsten composite is promising material with integrated shielding and structural properties for use in nuclear industry.

“…Subsequently, the Er 2 O 3 nanoparticles were selected for their ability to act as gamma rays absorbers thanks to the high atomic number of the Er. 29,30 In a further effort to achieve a fully connected network between the hybrid constituents, each reinforcing phase was subjected to a surface modification to allow the creation of physico-chemical links between all the components. Finally, the effect of the Er 2 O 3 amounts on the mechanical, ballistic and nuclear shielding performances was thoroughly studied to unravel the best ratio allowing optimal performances.…”

In this study, a new high-performance hybrid material was designed targeting an efficient ballistic and nuclear shielding protection. To achieve this goal, a typical highly performant thermosetting resin, namely the phthalonitrile (PN) resin, was reinforced with Kevlar fibers (KF-29), as continuous phase, and erbium oxide (Er2O3) nanoparticles, as discontinuous phase. The reinforcing phases underwent a silane surface modification to create a fully connected network aiming an improved stress transfer between the constituents. The mechanical investigations through tensile and bending testing confirmed the positive effect of the addition of an increasing amount (up to 20 wt%) of the Er2O3 nanoparticles. The hybrids also provided excellent gamma rays shielding performances with a screening ratio of about 33% for a 3 cm thick sample. In the meantime, the ballistic tests evaluated under the National Institute of Justice standard (NIJ standard-0101.06-IIA) also highlighted an improved kinetic energy absorption following the increase in the amounts of the discontinuous phase. Overall, this study unraveled for the first time ever the benefits obtained from a fully connected hybrid network in the field of ballistic and radiation protection.

Preventing X‐rays from reaching the human body is of great significance for the safe implementation of a wide range of related technologies. However, the current materials are commonly accompanied with low mechanical properties and backscatter radiation hazards. In this study, a structural material with high mass attenuation coefficients in a wide energy range (10–100 keV) is developed. The integration of high‐Z elements in hierarchical collagen nanofibers strongly reduces the backscatter radiation, resulting in only 28% of secondary radiation compared with a standard lead plate. The water vapor permeability of the engineered leather is nearly 340 times higher than commonly used synthetic and natural polymers. Compared with the commercial rubber‐based materials, the tensile strength of the engineered leather increased to 27.22 MPa (tenfold increase) and tear strength to 78.5 N mm−1 (threefold increase), respectively. A fully tailored engineered leather suit provides a 24.7% lower metabolic rate of locomotion and 67% reduced body heat compared with commercial lead aprons, which can facilitate better performance and safety during intensive activities in the health care and nuclear industries. This work lays a foundation for the engineering of next‐generation X‐ray shielding materials with potential large impact on the X‐ray application landscape.
