“…A comparative study of the same type of PP reinforced with E-and Mtype glass fibers (6 mm in length) showed an increase of impact strength from 6 J/m to 14 and 16 J/m, respectively. 12 This comparison reveals PROPERTIES OF BASALT FIBER-REINFORCED PP the real capabilities of basalt fibers for reinforcing of the isotactic polypropylene (iPP) matrix. The poor adhesion between the iPP matrix of the above-discussed samples and untreated basalt fibers was found on the fracture surfaces by SEM observation (Fig.…”

ABSTRACT:In the present article, a series of commercial-grade polypropylenes (PP) filled with different contents of short basalt fibers were studied. This composite material presented deterioration of both mechanical characteristics, for example, stress and strain at yield with increasing of the fiber content. On the other hand, the impact strength was fourfold higher than that of unfilled PP. A poor adhesion between the PP matrix and the basalt fibers was detected. This is why interfacial interactions were promoted by the adding of poly(propylene-g-maleic anhydride) (PP-g-MA). It was observed that the tensile properties of the obtained materials and their impact strengths increased significantly with increasing of the amount of PP-g-MA in the blend. The adhesion improvement was confirmed by scanning electron microscopy as well. Fourier transform infrared spectroscopy was applied to assess if any chemical interactions in the system PP/PP-g-MA/basalt fibers exist. Dynamic mechanical thermal analysis data showed an increase of the storage modulus with increasing fiber content. The conclusion was made that the modification of the PP matrix led to a higher stiffness but its value remained constant, irrespective of the PP-g-MA content. With increasing fiber content, damping in the ␤-region decreased, but increase of the coupling agent content restored its value back to that of PP. The loss modulus spectra presented a strong influence of fiber content on the ␣-relaxation process of PP. The position of the peaks of the above-mentioned relaxation processes are discussed as well.

“…The mechanical performances of PP can be further enhanced by adding inorganic fillers. The most commonly used low-cost fillers for PP include talc, calcium carbonate, short glass fiber and mica [1][2][3][4][5][6]. However, a large volume fraction of fillers, ca [25][26][27][28][29][30] % is needed to achieve desired mechanical properties.…”

Isotactic polypropylene (PP) nanocomposites containing 0.1, 0.3, 0.5 and 1.0 wt % silver (Ag) nanoparticles were prepared via melt compounding in a twin-screw extruder followed by injection molding The effects of the Ag nanoparticle additions on the structure and mechanical behavior of PP were studied using DSC, WXRD, optical microscopy, tensile and Izod impact techniques. DSC and WXRD measurements showed that the addition of only 0.1 wt% Ag nanoparticles promote the formation of β-form PP. Further increasing Ag content would not lead to additional increase of the β-PP phase content. The induced β-form PP phase is beneficial to enhance the impact strength and tensile ductility of the PP/Ag nanocomposites.
