Synthesis, Mechanical, and Thermal Properties of Composite Materials Based on Secondary Polypropylene and Modified Basalt Fibers

Composite materials based on secondary polypropylene and short-chopped basalt fibers are presented. Composites contain from 5 to 20% basalt fibers; each composite is heated at a temperature of 500, 650, and 750°C. For all samples, stress–strain curves are obtained. The tensile modulus reaches 2120 M...

More Information
Summary:Composite materials based on secondary polypropylene and short-chopped basalt fibers are presented. Composites contain from 5 to 20% basalt fibers; each composite is heated at a temperature of 500, 650, and 750°C. For all samples, stress–strain curves are obtained. The tensile modulus reaches 2120 MPa at a basalt fiber content of 20%, while for the initial secondary polypropylene this modulus is 705 MPa. The strength is 44.5 MPa (for the initial secondary polypropylene, this value is 32.0 MPa), and the specific impact strength is 18.3 kJ/m 2 (for the initial secondary polypropylene, this value is 14.4 kJ/m 2 ).
