Effect of NaOH on Some Physical Properties of Novalac /TiO2 Composite

Abstract

Aim of present work is to evaluate the tensile strength, impact strength, and hardness of (Novalac/TiO2) composite with (Vf = 12% optimum value of volume fraction for calculating properties) of prepared by open molding (hand lay-up) technique. Thermal conductivity (k), and weight gain % after immersed in NaOH solution 0.5 M for 60 days were calculated.                               Results showed a decreasing in mechanical properties with different ratios, Diffusion coefficient (D) calculated (D=2.3 *10-12 m2/sec).
