Effects of Composite Formulation on Mechanical Properties of Biodegradable Poly(Propylene Fumarate)/Bone Fiber Scaffolds

Figure 3

The main effects of the parameters on the compressive modulus of the crosslinked PPF composites. A positive number indicates an increase in the modulus as the parameter was changed from a low (−) level to a high (+) level. A negative number indicates a decrease in the modulus as the parameter was changed from a low (−) level to a high (+) level. Error bars represent the standard error of the effect (dry ± 16.5 MPa, wet ± 6.2 MPa).
