SiC nanoparticles) group and Reinforce heat cure acrylic soft liner (0.6% wt. SiC nanoparticles) group. the strength of the shear bond, hardness of soft liner/ NPs composites was measured, <br />Result<br />The results showed a highly significant increase in Shear bond strength and hardness of soft lining material at 0.6% and 0.4% wt sci NP compared to control specimens.<br /><br />Conclusion <br />the addition of silicon carbide nanoparticle into heat cure acrylic soft liner material improves mechanical properties such as surface hardness and shear bond strength.
