摘要
本研究的目的是评价(Novalac/TiO2)复合材料的拉伸强度、冲击强度和硬度(Vf = 12%为计算性能的最佳体积分数)通过开模(手铺)技术制备。计算在0.5 M NaOH溶液中浸泡60 d后的导热系数(k)和增重%。结果表明，不同配比下，材料的力学性能有所下降，计算出扩散系数D (D=2.3 *10-12 m2/sec)。
Effect of NaOH on Some Physical Properties of Novalac /TiO2 Composite
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).
