Novel hybrid composites based on polypropylene with basalt/carbon fiber (in English)
Polimery 2018, No 5, 387

Summary

Hybrid composites based on the homopolymer polypropylene Moplen HP500N reinforced with a mixture of basalt and carbon fibers in weight content of 10, 15 and 20 % were produced by injection molding. The density of these composites, their shrinkage and the Vicat softening temperature were determined. Tests of tensile and bending strength properties were carried out and Charpy impact was determined at three temperatures: -24, 22 and 80 °C. SEM images were taken to assess the effects of reinforcement and homogenization of composites and to determine the characteristics of their microstructure. Light-weight hybrid composites with already 10 wt % basalt fibers and 10 wt % carbon fibers are characterized by more than two and a half times increase in strength and over four times increase of the modulus of elasticity in a wide range of temperatures.
