Abstract

In this research, the study effect of additive titanium dioxide powder (TiO2) as a lone composite ( Ep+TiO2) and a mixture of (TiO2) and silicon oxide (SiO2), ( Ep+ TiO2+SiO2)as a hybrid composite on the mechanical and physical properties for epoxy coating. Thescompsiteswere prepared by (Hand Lay- the molding) method. The samples were tested for compressive strength, surface hardness, modulus of elasticity, thermal conductivity and diffusion coefficient, from the results obtained showed improvement in mechanical properties after adding ceramic powders, as the alone composite (EP+ TiO₂) had the highest compressive strength ( 53.738 ) ᴍPa, the hybrid composite ( EP+TiO₂+SiO₂ ) had the highest surface hardness (79.65), modulus of elasticity (1166.66 ) ᴍPa, impact strength ( 8.48) ᴍPa, thermal conductivity (0.4961 )watt/ m.c◦. As for the diffusion coefficient in the acidic solution ( HCL), the epoxy without adding the highest diffusion coefficient ( 31.3x 10^-10) m²/ sec while for immersion in ordinary water, the one composite material (Ep+ TiO₂) had the highest value of the diffusion coefficient (7.56x10^-10)m²/sec.
