Investigation of the physical and mechanical characteristics of biodegradable composites based on PHA

Among structural materials, an increasingly prominent role is played by polymers and composite materials based on them, in particular composites based on biodegradable polymers, which is due to their environmentally friendly properties and rather high physical and mechanical characteristics. The study of the strength characteristics of a biodegradable wood-filled composite based on PHA is presented in the article. Indicators such as impact strength, tensile and flexural modulus, strength and tensile elongation were analyzed. In the course of the studies carried out, it is revealed that the use of wood flour as a filler is advisable up to 30% of its content in the composite, since at higher filler contents, a significant decrease in physical and mechanical characteristics is observed.
