Glass transition temperatures (Tg), enthalpy of cold crystallization (Δhc), enthalpy of fusion (Δhm), and crystalline weight fraction growing during cold crystallization (wCc) and disappearing during fusion (wCm) for the PLA-based matrix and biocomposites (estimated errors: ± 0.5 °C for Tg; ± 1 J/g for Δhc and Δhm, and ± 0.02 for wCc and wCm).
