    EnTreHeaT

    The project ‘EnTreHeaT — Enzymatic Surface Treatment of Biogene Heavy Tows (bHT) for use in High-Performance Composites’ (CORNET, no. 01IF00417C) has been initiated by FIBRE. Since June 1st, 2025, research is performed in collaboration with Sächsisches Textilforschungsinstitut e.V. (STFI), Chemnitz, DE and InoTEX s.r.o, Dvůr Králové n.L., CZ, coordinated by Forschungsvereinigung Werkstoffe aus Nachhaltigen Rohstoffen e.V. (WNR), Rudolstadt, DE and Klastr technické textilie, z.s. (CLUTEX), Liberec, CZ. The project aims to improve the interaction of bHT and thermosets.

    Biogene Heavy Tows (bHT) are bark stripes peeled off from hemp stems. They can be as long as the plant and can be used (like commercial rovings) as unidirectional reinforcement in composites. The covering substances on the bHT surface can be removed by enzymatic treatment in order to uncover the surface-near fibres. This enables a direct fibre-matrix coupling. Using this technique, the core of the bark stripes remains unchanged, and the mechanical properties of the composite can be improved significantly. [Link to project flyer]

  • FIX3HYB

    FIX3HYB

    In FIX3HYB, so-called draping molds are developed for the three-dimensional shaping, fixation, and stabilization of the hybrid textiles used. Systems such as pins, Velcro fasteners, and snap fasteners are used for fixation. Additional elements are used as needed to secure the interlayers. In addition, the textiles are pre-compacted using 3D shell elements, so that the inserts are enclosed in a capsule-like structure. These “capsules” can be placed into heated molds during the thermoforming process and rapidly consolidated, whereby the draping form becomes an integral part of the component due to its matrix compatibility with the matrix fibers of the hybrid textile.

    Process development in the project will initially take place at the laboratory level and will subsequently be scaled up to the industrial level. In particular, fiber pre-drying and impregnation quality will be examined, and the process parameters will be optimized iteratively. The mechanical properties of the profiles will be characterized through tensile, compressive, and flexural tests. In addition, the influence of the process parameters on surface quality, porosity, and residual moisture content will be evaluated. More…

    KaskaWi

    The “KaskaWi” collaborative project is developing new approaches to keep FRP from end-of-life construction waste in the material cycle for as long as possible. Instead of shredding the components, the goal is to specifically reuse suitable components and semi-finished products in new construction applications based on their remaining properties. To this end, the materials are characterized, classified, and assigned to suitable second-life applications. Demonstrators such as facade elements and substructures for photovoltaic modules demonstrate the practical feasibility of this approach. A Digital Product Passport (DPP) and a damage model provide the foundation for tracking the condition and usage history of components and enabling further usage cycles. More…

  • PERSEPHONE

    PERSEPHONE

    Membrane-supported capacitive deionization (MCDI) is an electrosorption process for the selective separation of ions with low energy and chemical consumption. The goal of this project is to develop a novel process for recovering phosphate from wastewater and/or surface water with low capital and operating costs, based on cotton and the MCDI process. The phosphate is concentrated, separated, and then recovered using two-phase capacitive membrane deionization. The recovered phosphate is intended to serve as a raw material for phosphorus fertilizers. More…

  • KRYOSTAND

    KRYOSTAND

    The research focus of the KryoStand project is on the development and standardization of mechanical testing methods for fiber-reinforced plastic composites (FRP) and plastics under cryogenic conditions. The goal is to identify and analyze the various factors influencing material testing at extremely low temperatures ranging from 150 °C to below 252 °C (the boiling point of hydrogen) and, thereby, to adapt existing testing methods—which are designed for near-room-temperature testing—to create reliable testing methods for cryogenic temperatures. Only in this way can the safety and efficiency of these materials be ensured in future-oriented technology fields such as hydrogen technology and the associated mobility sectors, as well as aerospace—supported by sensor technology for structural monitoring.

    Testing the mechanical properties of reinforcing fibers—such as carbon, glass, basalt, or ceramic fibers, as well as recycled fibers—is becoming increasingly important, as lightweight construction techniques are being used in more and more fields to conserve resources. A meaningful, fast, and reliable testing method is essential for quality control of these fibers. Single-fiber tensile tests serve this purpose. To quickly and easily determine the mechanical properties, it makes sense to clamp the fibers directly into suitable clamps and test them, rather than having to laboriously affix them to individual paper frames in accordance with ISO 11566. At the same time, the fineness of the individual fibers in the section of the fiber being tested should be determined—a vibroscopic measurement is used for this purpose. The WiBreak project is focused on developing a foundation for
    standardization. More…

    QuasiPuR

    The goal of the project is to develop a quality assurance system for the continuous pultrusion process used to manufacture fiber-reinforced plastic profiles. Using X-ray CT technology, pultruded products will be measured in-process (inline), and the generated measurement data will be automatically interpreted to immediately identify, classify, and quantify defects.

  • OSLAPRO

    The project „OSLAPRO – Optimization of the SLA process using non-destructive testing methods for the targeted manufacture of components and injection molds” (BAB: Funding of Research, Development and Innovation (EFRE-FEI), application number: 65008333) started on 1 July 2025. The project involves collaborative research and development with Kolbes Messtechnik OHG. The project develops a data-driven, methodologically robust approach to improving SLA (stereolithography) mold inserts for Freeform Injection Molding. It links process parameters, material behaviour, and defect mechanisms. The aim is to speed up industrial readiness and achieve reliable, long lasting tool performance.
