However, there is a limited number of works available, on the particular under dynamic perspective. Based on this, the static and dynamic compression properties of polypropylene/silica composites, with particle sizes of 3 μm, 1 μm, 20 nm, and 11 nm, were successfully studied at different levels of strain rates (i.e., 0.01 s−¹, 0.1 s−¹, 650 s−¹, 900 s−¹, and 1100 s−¹) using a universal testing machine and a split Hopkinson pressure bar apparatus. Results show that the yield strength, the ultimate strength, and the stiffness properties, of polypropylene/silica composites were greatly affected by both particle size and loading rates. Furthermore, particle size also influences the rate sensitivity and the thermal activation volume of polypropylene/silica composites; where, smaller particle recorded lower rate sensitivity. Meanwhile, for the thermal activation volume, the trend was reversed. 2014-03-11T03:18:24Z 2014-03-11T03:18:24Z 2013-03 Article Materials & Design, vol.45, 2013, pages 539-547 0261-3069 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32494 http://www.sciencedirect.com/science/article/pii/S0261306912006577 http://dx.doi.org/10.1016/j.matdes.2012.09.026 en Elsevier |
