| Riassunto: | Title screen Hybrid composite materials reinforced with unidirectional fibers and small-scale micro- or nanoparticles provide benefits compared to traditional composites. The present paper shows the experimental investigation of carbon-fiber-reinforced polymers modified by the addition of 0.5–5 wt% of milled carbon fibers and 0.1–0.5 wt% of single-wall carbon nanotubes. Both fillers were analyzed from technological point of view. The impact on mechanical and physical properties was revealed and discussed. Main attention was paid to quasi-static tensile and flexural properties as well as fatigue behavior under tension–tension mode. The maximal improvement in static tensile strength by 8.6% (from 682 to 741 MPa) and flexural strength by 14% (from 649 to 740 MPa) was achieved by the addition of 0.3 wt% single-wall carbon nanotubes. Short beam shear strength increased by 18%. Fatigue durability was highly improved as well. The strengthening mechanisms are attributed to the improvement of shear interfacial properties. In contrast to single-wall carbon nanotubes, milled carbon fibers enhanced the properties by 3%–9% only at static loading, while fatigue properties are negatively affected. |
