Description
Summary:Polymethyl methacrylate nanocomposite including CuO, TiO 2 and Al 2 O 3 nanoparticles (NPs) was studied as an interlayer to enhance properties of ultrasonically welded glass fiber reinforced plastic. Synthesized NPs were characterized by SEM and XRD methods. A multiple regression model based on response surface methodology by using the input parameters of welding time, NP’s weight percentage and thermal conductivity according to analysis of variance was developed. Results showed that applying 2 bar pressure, 0.5 s holding time, 1 wt% CuO, and 0.4 s welding time, the maximum breaking load of 2585 N can be obtained, while with 1 wt% TiO 2 and Al 2 O 3 breaking loads of 2198 N and 2069 N can be expected, respectively. Therefore, using CuO, TiO 2 and Al 2 O 3 NPs, an increase in the weld strength by a factor of 1.5 can be realized.
