Micro-Mechanics of UPR Composite Toughened by Rigid Nano-Particles
The toughening for UPR composite effect of rigid nano-particles was studied. By the tensile test, it was confirmed that with the increase of the organic rigid particle PA6 and inorganic rigid nano-particles SiO2，toughening effect for the UPR was better. The Generalized Method Cell of the micro-mechanical constitutive of the rigid particles and UPR phase was established. The macro- plastic deformation was simulated by the correlation of parameters for micro-mechanical and macroscopic mechanical, the simulation curves were well fit with its experimental curves。The numerical results indicate that the nonlinear theoretical method can simulate the plastic strain curves of composite well.
