“…Therefore, non-toxic ''lead-free'' filler-reinforced polymer composite for its lightweight, workability, and ability to effectively attenuate radiation has aroused great public interest in many areas, especially in medical treatment, nuclear plant and mobile nuclear devices. For example, the ethylene-propylenediene rubber (EPDM)/low density polyethylene (LDPE) mixed with boron carbide has been widely used for neutron shielding [4], and the polydimethylsiloxane (PDMS) blended with bismuth oxide (BiO) nanoparticles used to shield against X-ray with the voltage range from 40 to 150 kV [3]. But their poor mechanical strength, low thermal stability and radiation resistance make them not suitable for a long-term use.…”

“…Therefore, the most suitable composite material according to the defined criteria is composed of a phenolic resin matrix reinforced with long boron fibres. This selected composite exhibits another additional interesting feature, since boron has the ability to reduce the speed of neutrons 24–26 and, so, this material could have a secondary function as protection shield against neutronic radiation.…”

This study describes a methodological proposal to select composite materials which are suitable to be employed to manufacture pipes that can properly withstand environments subjected to gamma and neutronic radiation. The methodology is used to select, among many others, the optimal composite material whose properties are used afterwards to simulate several pipe sections by finite element analysis, comparing the results with a well-known nuclear-grade steel, WWER 15Kh2MFAA. The most suitable composite material according to the defined criteria is composed of a phenolic resin matrix reinforced with long boron fibres and exhibit great properties to be used in a nuclear reactor environment: good radiation resistance and mechanical properties with a very low density at low cost. It can be concluded that, in some cases, composite material pipes can be a better option than steel ones. Extending the method to be employed in other industries or with other components could be seen as future works.

“…However, the tensile strength of the composite was only 26 MPa. Additionally, ethylene‐propylene‐diene monomer rubber (EPDM) mixed with heavy metal element (Bi–W–Gd–Sb) oxides and boron carbide composites were prepared. Huang et al studied the radiation shielding property and mechanical property of PbWO 4 /EPDM composite.…”

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.
