Toughness versus stiffness of PP particulate composites modeling and experimental approach
Original language description
This contribution is focused on particulate composites, namely on composites with polypropylene matrix (PP) and rigid (CaCO3) fillers. Generally, the addition of rigid particles to a polymeric matrix has an embrittling effect on the composite. Using veryfine isometric filler of sub-micron range with proper surface treatment and good final dispersion enable to achieve enhancement of toughness without significant reduction of its stiffness. The role of filler size and interphase properties on micro- andmacro-behaviour of particulate composites is analysed from the experimental as well theoretical point of view. The attention is focused on fracture toughness and stiffness values. It is concluded that one of the possible sources of a toughening mechanismon micro- level is a blunting of the micro-crack caused by its interaction with coated particles. The results of numerical simulations are compared with relevant results determined experimentally.
