For collagen reinforced alginate, how will the failur strain change with changing the volume fraction of each component?and alginate concentration?

is it true to say that the mechanical properties (tensile strength and stiffness) are mainly affected by the collagen volume fraction, while the failure strain/compliance are affected by the...
