Interphase structuring for improved toughness according to biological principles (B03)

• Subject Area: Polymeric and Biogenic Materials and Derived Composites ; Lightweight Construction, Textile Technology
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 417002380

The primary goal of the project is the transfer of material concepts found in biological structures that allow high toughness in composites by the implementation of bioinspired transition zones between impregnated reinforcing textiles to the concrete matrix. Alternating layers of organic and inorganic materials as well as open-cell polymer structures are implemented in interphases to achieve enhanced fracture toughness and to avoid cleavage cracks between textile reinforcing structures and concrete under high stresses.
