The epoxies are usually heavy and viscous materials with a molecular weight of approximately 370, with a wpe (weight per epoxide group) of about 180 and a viscosity of 1100 to 1500 mPa-s at 25°C. - 2 - Several factors affect the behaviour of epoxies subjected to ionizing radiations, including the radiation environment and the presence of additives.

The epoxy resin utilised in this work was E−110I/H-9 type, which falls under the category of thermosetting polymers. The molecular formula of epoxy resin is C 21 H 25 ClO 5 and its density is 1.1 g/cm 3. It consists of two parts, namely, a resin with epoxide rings at the ends of its molecules type (E−110I) and a curing agent or hardener.

Herein, carbon-doped boron nitride (BCN), modified by two silane coupling agents, was used to fabricate epoxy composites, and the effect of gamma irradiation on the properties of epoxy resin composites was investigated. The research showed that the modified BCN/epoxy composites prepared herein exhibited excellent mechanical and thermal.

Present work deals with the nonlinear finite element analyses of ultra-high molecular weight polyethylene (UHMWPE). UHMWPE has been presented for ballistic design investigation of lightweight body armour using ANSYS-Workbench. The ballistic performance of UHMWPE has been compared with Kevlar/epoxy composite and alumina. The study is presented in terms of the ballistic limit of UHMWPE, Kevlar.

Epoxy resins are a good candidate for radiation shields owing to their low cost, high strength, low toxicity, resistance to corrosion, excellent mechanical properties, and low shrinkage. [ 9, 10, 11] These characteristics make epoxy composites a desirable shield to attenuate neutrons, X-rays, and gamma rays.

The aim of the current study is to investigate the impact of introducing micro- and nanoparticle MgO as a filler into epoxy resin on the radiation shielding abilities of the prepared samples. To this end, we performed a gamma-radiation spectroscopy experiment with the help of an HPGe detector and Am-241, Cs-137, and Co-60 sources. We evaluated the particle size effect (PSE) and detected the.

The gamma irradiation treatment of epoxy resins composites offers many advantages compared with conventional thermal curing, such as a reduced time, ambient temperature, greater flexibility [5], changes in physical, optical, electrical properties, or morphological structure [2,9,10]. Often, epoxy resins are amorphous in nature and it is.
