Influences of NBR/Al2O3/YSZ as Fillers for PMMA Composite on the Thermal Properties

Abstract

The aim of this study is to investigate the effect of nitrile butadiene rubber (NBR as impact modifier) together with Al2O3/YSZ (toughening) as different filler ratios in PMMA material on the DSC thermal properties. PMMA matrix without fillers was mixed between PMMA powder and 0.5 wt.% of BPO and fixed at 7.5 wt.% of NBR particles with different ratios of filler (1, 3, 5, 7 and 10 wt.%) of Al2O3/YSZ mixture filler by (1:1 ratio). The TGA data were shown that the PMMA composite have better thermal stability compared to unreinforced PMMA matrix. While, DSC curves shows slightly similar in Tg value. DSC results also indicated the presence of unreacted monomer content for both reinforced and unreinforced PMMA composites. As conclusion of this study, the reinforced PMMA composites are improved in thermal stability compared to unreinforced PMMA matrix.
