Static and dynamic compressive properties of mica/polypropylene composites

摘要: Abstract The static and dynamic properties of mica/polypropylene composites, with a mica content 10, 15, 20% by weight, were studied at different levels strain rates (from 10 s−4 to 10 s2), using conventional Universal Testing Machine Split Hopkinson Pressure Bar apparatus. results show, that the mechanical in terms yield stress, fracture strain, compression modulus compressive strength, greatly affected level applied content. It was found Bergstrom model both consistent reliable, evaluating effect hardening mechanism respect rate. relationship between rate sensitivity thermal activation volume composites successfully obtained various contents, where show contradicting pattern for parameters.
