Název v původním jazyce

The effect of an interphase on micro-crack behaviour in polymer composites

Popis výsledku v původním jazyce

The present chapter is focused mainly on polypropylene based composites filled by mineral fillers, but some results can be generalized for other particle composites. The stiffness and toughness of the composite is modelled using a three-phase continuum consisting of the polymer matrix, mineral particles and an interphase between them. It is shown that the effect of the interphase on the macroscopic characteristics of the composite is decisive. Generally, the addition of the mineral filler to the polymermatrix leads to ebrittlement of the composite. It is shown that properties of the interphase control both the stiffness and embrittlement of the particulate composite. Primarily, the interaction of micro-cracks with coated particles is studied. It is concluded that in some cases of the microscopic particles, size and specific interphase properties and the addition of mineral fillers can lead to a good balance between fracture toughness and stiffness.
