In the current study, the low-velocity impact behaviour of composite materials obtained from carbon and carbon-aramid hybrid woven fabrics of different constructions, produced from the same yarn and under the same production conditions, was determined, and the effects of the weaving structure and hybridisation on the low velocity impact properties were investigated. Depending on the weaving structure, the best results were obtained for twill woven composites. The energy absorption capacity was increased by around 9 - 10% with hybridisation. It was observed that peak load values varied with a coefficient between 0.84-0.97 for hybrid composites, whereas the range was 0.49 - 0.87 for 100% carbon composites, depending on the bending stiffness.

Badano materiały kompozytowe uzyskane z hybrydowych tkanin węglowych i węglowo-aramidowych o różnej konstrukcji. Tkaniny wyprodukowane zostały przy zastosowaniu jednakowych przędz i tych samych warunków produkcji. Badano wpływ zastosowanych tkanin na zachowanie się kompozytów podczas obciążeń realizowanych z małą prędkością. Biorąc pod uwagę strukturę tkanin, najlepsze rezultaty uzyskano przy tkaninach o splocie skośnym. Absorpcja energii była zwiększona o ok. 10% w przypadku hybrydyzacji. Zaobserwowano, że wartości pików obciążenia zmieniały się przy współczynniku 0.84 - 0.97 dla kompozytów hybrydowych, podczas gdy współczynnik ten wynosił od 0.49 - 0.87 dla 100% kompozytów węglowych w zależności od sztywności zginania.
