Original abstract
Polymeric particulate composites with thermoplastics, especially polypropylene (PP) matrix and mineral fillers, are of great practical importance due to the possibility of modifying mechanical properties and reducing the price/volume ratio of resulting material. The addition of mineral fillers to polypropylene (PP) profoundly changes the mechanical properties of a polymer system. The properties of the particles themselves (size, shape, material properties) can have a significant effect on the global behaviour of the composite. Generally, the addition of rigid particles to a polymer matrix will have an embrittling effect on the composite. Most studies on modification of thermoplastic composites with rigid mineral fillers report a significant decrease in fracture toughness compared with the neat polymer.
