Název v původním jazyce

Prediction of the behavior of lime mortar reinforced with fibers based on their micromechanical parameters

Popis výsledku v původním jazyce

For the purpose of restoration works a new fiber reinforced composite material with lime matrix is being developed. Fibers act as dispersed reinforcement, which, after matrix cracking, ensures that the material retains macroscopic integrity and makes itpossible to limit the cracks width. The behavior of individual cracks in fiber composite can be controlled by its composition and by the micromechanical parameters of fibers, matrix and the fiber-matrix interface, which we utilize to optimize the material design. To this end, we have chosen several types of fibers and their micromechanical parameters and the parameters of the interface were experimentally investigated. The obtained values were used to numerically simulate the cohesive behavior of a single crack. These numerical simulations are performed for different lengths and volume fractions of fibers. Results will serve as a basis for selection of suitable fiber type, length and volume fraction to be used in the developed composite
