CG scaffold and scaffold-membrane composite mechanical properties (n = 8). A) Characteristic stress-strain curves, B) tensile elastic modulus, C) yield stress, and D) yield strain. While perforated composites display significantly higher tensile elastic moduli and yield stress compared to scaffolds alone, they are not as strong as monolithic, non-perforated composites. #: significantly greater than all other experimental groups, &: significantly greater than no membrane group. Error bars indicate standard error of the mean.
