Effect of Functional Disperse Fillers on Mechanical Properties of Fibrous Polymeric Composite Materials

Resumo

Oriented fibrous polymeric composite materials based on polyethyleneterephthalate, polypropylene, and polylactide matrices and fillers of various types and chemical nature were obtained by a melt technique. The effect of added fillers on the mechanical properties of the oriented composites was studied. It was shown that with the addition of various types of fillers there is an optimum concentration that leads to increase of the strength and rigidity in the oriented fibrous composite materials, and this is determined by the type and form of the disperse particles.
