Numerical Material Testing of Mineral-Impregnated Carbon Fiber Reinforcement for Concrete

Research output: Contribution to journalResearch articleContributedpeer-review



Abstract: This work was dedicated to the simulation of fiber composite structures consisting of carbon
fibers and mineral impregnation. The aim of this study was to generate a micromodel that predicts the
properties of a mineral-impregnated carbon fiber reinforcement. The numerical characterization was
based on the discrete microscopic modeling of the individual phases using a representative volume
element. In addition, the stochastic nature of the fiber strength, the anisotropic damage mechanisms
of the brittle matrix, and the non-linear bonding behavior between the filaments and the matrix were
considered in the material models. The material models were adjusted based on the literature sources
and our own experimental investigations. This was followed by the validation of the representative
volume element, quantifying the evolution of stiffness and damage under longitudinal tensile loading.
The numerical results of material stiffness, as well as the tensile strength of the representative volume
element, were compared with the results of the experimental investigations. To verify the robustness
of the numerical model, significant model parameters were subjected to a sensitivity analysis.
