Highly advanced math models are presented as proof validation of Micromechanics for predicting overall properties with fibers in composite materials in addition to accurate comprehensive mechanical test methods. An extension of material properties for fiber-reinforced composites readily applies to Cell Biology at the micrometer level for the cytoskeleton and surrounding extracellular matrix fibers. Advanced understanding of free radicals needed in providing exact cure conditions for polymer matrix composites can then be easily applied to free-radical theory in Biology and Medicine....
