An essential aspect of the DSC analysis in the context of this research was the estimation of the degree of crystallinity of the produced materials. The manufacturing process was designed to achieve similar degrees of crystallinity within each material group, as the degree of crystallinity can influence the mechanical properties of the material. If the crystallinity varied significantly, it would be difficult to determine whether a given effect was due to the filler size or the degree of crystallinity. Consequently, all PLA-based materials exhibited a degree of crystallinity close to zero, while the PCL-based materials had a similar crystallinity level, ranging from 50-55%. Tg -glass transition temperature, Tcc -temperature of cold crystallisation, Tm -melting point, ΔHcc -enthalpy of cold crystallisation, ΔHm -enthalpy of melting, Xc -degree of crystallinity, Tc -temperature of crystallisation, ΔHcc -enthalpy of crystallisation.
