Study of Mechanical Properties of Magnesium Oxysulfate Whisker/ABS Composites

Abstract:

The magnesium oxysulfate whisker/ABS composites were prepared by making the magnesium oxysulfate whisker as dispersed phase.Scaning electron microscope(SEM) was used to test the distribution of whiskers in ABS matrix.Effect of the surface modification and the amount of whiskers to the mechanical properties of composites were studied.The results show that,the surface modification can improve effectively dispersity both itself and in ABS matrix,interface acting force between ABS matrix and whiskers, and mechanical properties of composites ,remarkably.When the mass ratio of whisker to ABS is 40/100,the composite owns the optimum mechanical properties(Tensile strength,elastic modulus,and elongation at break are 67.5Mpa, 7.50Mpa,4.70%,respectively), whiskers distribute uniformly in matrix and improve the dimensioned stability of composites.The reinforcement mechanism of whiskers in ABS was also studied to explain the experimental results.
