Polymer composite materials based on a binder from renewable raw materials: the effect of a filler on the physical and mechanical properties

Polymer composite materials have been developed using polyester-urethane-acrylate resin based on 2,5-furandicarboxylic acid obtained from plant biomass and a number of synthetic (carbon, glass, and aramid fibers) and mineral (basalt) fibrous fillers. The high operational characteristics of the obtained PCMs are demonstrated. The effect of hybridization of synthetic fibers with natural cellulose fibers (cotton) on the physical and mechanical properties of polymer composite materials has been studied. An increase in tensile strength with a simultaneous decrease in the density of PCM using a carbon fi ber/cotton hybrid filler is shown.
