Abstract
The effect of tensile loadings and proportions of carbon fiber on the allowable stress calculations and static failure analysis of carbon fiber epoxy composites were investigated under uniaxial tensile loadings. Micromechanical modeling analysis was applied to model the failures of composites at the continuum length scale. The results obtained from molecular dynamics analysis of graphene and epoxy, were utilized as inputs in the MAC/GMC micromechanics software to model and evaluate the allowable stress values and static failures of carbon fiber reinforced epoxy composites.
The computed results for composite elastic allowable stress estimation for the average materials and the static failure analysis were compared and these results were in agreement. The study has added to the understanding of the failure mechanism of the carbon fiber reinforce epoxy composites as well as the interactions of the constituents at failure.
