Modified epoxy composites have become attractive materials for various applications including coatings, polymer concrete,
and with asphalt as steel bridge pavement material. In such applications, it is important to maintain high chemical and
mechanical resistance to avoid load cracking and corrosion resulted from chemicals exposures. The purpose of this study is to
produce sulfur/epoxy composites with excellent mechanical and chemical properties and able to be applied easily in a wide
range of applications. The epoxy resin was mechanically mixed with different percentages of sulfur and linseed oil to form
sulfur/epoxy composites. Where sulfur is well incorporated into the epoxy matrix. The prepared composites were
characterized by dynamic mechanical analysis including storage modulus, loss modulus, and tan delta. In addition, the
chemical and water absorption resistance was tested including two hours boiling water absorption resistance and long-term
water absorption resistance. The results showed enhanced storage modulus, glass transition temperature, chemicals, and water
absorption resistance. Also, it is observed that as the concentration of sulfur increases, the mechanical and chemical resistance
properties increase. |
