Abstract
The mechanical properties and structure of composites filled with short basalt fibers (SBF) based on blend of polypropylene (PP) and metallocene ethylene-propylene elastomer (mEPE) are studied. It has been shown that the introduction of SBF in the PP/mEPE blend while ensuring good adhesion fiber-matrix by adding maleated polypropylene (MAPP) lead to significant increases in the modulus of elasticity and the tensile yield stress. When tested with notched specimens, the impact strength of PP/mEPE/SBF/MAPP composites improves with increasing fiber content. This trend is also observed in the case of un-notched specimens only at low test temperatures. To explain the observed phenomena, the influence of introduced fibers and test conditions on crack nucleation and crack propagation is proposed.
