Figure 3. Mechanical compression testing of PLA cage, scaffold, and various collagen-PLA composite designs.

Figure 3.

(A) Representative images of stress-strain curves comparing all experimental conditions, PLA cage vs. collagen-PLA composite, collagen scaffold vs. collagen-PLA composite, and between all composite designs. (B) Young’s modulus and Ultimate stress for all scaffold, cage, and composite designs. * indicates significantly (p < 0.05) higher value than scaffold. Data expressed as mean ± standard deviation (n=8).
