Compare the minimum critical fiber aspect ratios for E-glass, T-300 carbon, P-100 carbon, and Kevlar

Compare the minimum critical fiber aspect ratios for
E-glass, T-300 carbon, P-100 carbon, and Kevlar 49 fibers in an epoxy matrix.
Assume that the epoxy matrix behaves as an elastic, perfectly plastic material
with a tensile yield strength of 10,000 psi.
