Mechanical properties of spread carbon fiber reinforced polymer containing microcapsules were predicted by using representative volume element (RVE) models. Firstly, we employed finite element analysis (FEA) to discuss the effects of microcapsule volume fraction, dispersion state and diameter on the elastic properties of RVE models of spread carbon fiber reinforced polymer containing microcapsules. Then, FEA of short beam shear testing was performed using the predicted elastic properties from the RVE models, and the analytical results were compared with the experimental results to validate the RVE models. Finally, we investigated damage progression behavior of the RVE models to study the damage distributions within the spread carbon fiber reinforced polymer containing microcapsules. The results indicated that comparisons with the analytical and experimental results showed reasonably a good agreement. Therefore, the RVE models were effective to predict the mechanical properties and can contribute the design of microstructure for self-healing spread carbon fiber reinforced polymer.
