Toughness of brittle–matrix composites with heterogeneous reinforcement

Original language description

Elastic properties of fibrous composites are conveniently modeled by rules of mixtures which appropriately combine the elastic properties of individual constituents and allow for a homogenized representation of the composite behavior. However, elasticity may be lost at load levels far below the ultimate performance of the composite due to matrix and/or fiber damage and fiber debonding. It has been proved that statistical-mechanical models perform well for the inelastic range of composites mechanics. This article describes a statistical-mechanical model which introduces the possibility to simulate heterogeneity in bond properties. The model is appropriate e.g. for the newly developed composite material textile reinforced concrete (TRC), where the bond heterogeneity is caused by irregular penetration of the cementitious matrix into the structure of reinforcing multifilament yarns. It is shown that the heterogeneous bond significantly reduces the composite strength.
