Abstract
The present invention relates to a lead free glossy finish hybrid radiation shielding composite panel comprising: a) 40-70% of industrial waste red mud and 30-60% of epoxy/polyester resin with or without glass fibre, wherein the composite panel has density in the range of 1.4-2.2 g/cc; water absorption in the range of 0.20-0.30%; tensile strength in the range of 12-120 MPa; tensile modulus in the range of 1.5-7.5 GPa; and half value layer in the range of 0.36-0.47 cm and 0.48-0.52 cm for X-ray beam energies of 60 and 100 kVp, respectively. The present invention also describes a low temperature process for manufacturing the composite panels. Moreover, the developed composite panel is a unique material and have multifunctional applications in wider spectrum as high energy electromagnetic radiation shielding doors, panels, partition panels and as roofing sheets.
