Abstract

To benefit from nano-rubber copolymers, the properties and dynamic behavior of nano-rubbers reinforced Poly(Methyl Methacrylate) (PMMA) were investigated. Dynamic tests were conducted on these materials at high strain rates and different temperatures using split Hopkinson pressure bars. The impact resistance of these materials was studied by performing low velocity impact tests with a drop weight tower at different impact energies and temperatures. The results showed decreased Young’s moduli and yield stresses. The mechanical behavior of the materials exhibited strain rate and temperature dependencies. Moreover, the nano-rubber-reinforced PMMA showed outstanding impact resistance compared with neat PMMA. The modified PMMA also exhibited impact properties similar to those of polycarbonate for certain ranges of impact energies and temperatures. No perforations were observed for all those energies and temperatures.
