Mechanical properties of PLA and its composites. (a-b) Typical strain–stress curves of PLA and PLA composites: (a) PLA-CNW composites and (b) PLA-CS-CNW composites; (c) Young’s modulus of all samples. T-test results are displayed as letters on the top of columns. A column with the same letter represents no significant difference (p > 0.05). (d) Tensile strength and strain at break of PLA-CNW composites; (e) Tensile strength and strain at break of PLA-CS-CNW composites. ϵ represents stress. σ represents strain.
