International Research Awards on Fiberreinforced Polymer
Fiber reinforcement plays a pivotal role in the world of composite materials,
enhancing their structural integrity, strength, and performance. Composites, consisting of a
matrix material and embedded fibers, are used in various industries, from aerospace to
automotive and construction. Exploring fibre reinforced composites with a novel approach
for developing wearable radiation shielding devices in radiation protection, radiation
emergency and nuclear disaster management. Types of fibers commonly used in composite
materials, including carbon fibers, glass fibers, aramid fibers, and natural fibers, each
offering unique properties suited to specific applications. Although Lead has been the
traditional gold standard for wearable radiation shielding for many decades. Numerous
health and occupational hazards. (Lead Toxicity), Heavy weight , uncomfortable for
prolonged use. Work related Musculoskeletal disorders (WMSD) are associated problems.
Researchers are exploring advance new materials like Nylon-6 , KEVLAR ( aramid fibres) for
its mechanical strength and suitability in wearable composites for radiation protection. The
study explores innovative Nylon-6-based silicone rubber composites, incorporating fillers
effective in the 140 keV gamma to 511 keV positron energy range. Composites with 60%
bismuth oxide and 50% aluminium powder show exceptional mechanical strength and
superior radiation attenuation capabilities. Novelty of Nylon-6-based silicone rubber
composites offer a promising, lead-free alternative for wearable radiation protection.
Potential advancements in nanocomposites with bismuth and aluminum additives can
further enhance radiation shielding technologies.

Microscope (SEM) (ZEISS EVO 18 Special Edition): Observed microphotographs of samples.
Geiger Muller Counter (M/S Para Electronics Mumbai): Used to assess radiation parameters.
Results:
TSN-4 showed optimal performance across multiple energy ranges (140 keV to 511
keV). Comparison with Lead: TSN-4 shows promising results as a lead alternative.
Conclusion:
Nylon-6 based silicon rubber composites, particularly TSN-4, demonstrate
excellent mechanical and radiation attenuation properties. Potential to replace lead in
radiation shielding applications to develop wearable devices.
