Acid-resistant fibre-reinforced composites

Acid-resistant fibre-reinforced composites

The three-year collaborative project involved the interdisciplinary analysis of material-specific damage processes in biogas plants, the development of acid-resistant fibre-reinforced composites on the basis of novel bonding agent systems and, as a final step, the practical implementation of the fibre-reinforced composite that had been developed, through the optimisation of existing construction principles. 


Our partners in the project were Schwenk Zement KG, BioConstruct GmbH and the Institute of Mineralogy, Crystallography and Materials Science at Leipzig University. Biogasfachverband e.V. and the German Biomass Research Centre (DBFZ) were ideal sponsors for the project.

Development of cement-bonded composite construction materials with explosion-proof, bullet-proof and fire-proof properties 


The goal of the project to develop and experimentally validate new, innovative composite construction materials and concepts on the basis of hydraulic bonding agents that are particularly resistant to short-term dynamic loads (shots, explosions) and to fire and cave-in. This required developments in materials science and composite materials, taking account of the latest findings regarding the available starting materials, joining technology and analytical methods. The individual development steps had to be systematically aligned with each other, and the optimisations at the nano/microscale linked to the final application at the macro level. The different stress scenarios needed to be covered in the range of investigations carried out. The primary goal was to make available for practical use cement-bonded composite construction materials that offer a broad spectrum of applications for safety use and also meet all the other physical structural and technical requirements.

Development and application of sensor textiles for online monitoring of load-bearing structures and constructions 


The goal of this research project was to develop novel construction textiles for long-term monitoring (online monitoring) using stitching techniques. For this purpose, optical sensors were to be stitched onto textile structures (glass and synthetic textiles). In future, these sensor textiles should enable flexible, simple observation of tensile and compressive conditions on any component surface, with the observation being stable over the long term. To this end, the objective was to use epoxy-based adhesives to join the entire surface of the textile to the structure to be monitored. Here, the epoxy glue provides an additional effective mechanical protection for the measuring system by penetrating through the technical textile.

The effect of extreme fire scenarios on the load-bearing capacity and durability of bridge structures 


Vandalism, human error or accidents lead time and time again to fire incidents on and beneath bridges. The research project led to findings as to the consequences of extreme fire incidents. Various scenarios of a burning truck laden with wooden pallets were investigated for different types of bridge structure, as were scenarios of burning fluid escaping from a tanker. 


The progress of the fire and temperature profile were calculated using computational fluid dynamics (CFD), taking account of various influencing factors, and all the relevant adiabatic surface temperature/time curves were determined. The heat penetration behaviour was then calculated using transient FEM calculation. 


In the case of fires beneath bridges, the simulations indicated temperatures of the sort that occur in tunnel fires. The progress of the fire could therefore be suitably approximated by the ZTV-ING or the extended ZTV-ING curve. 


In the case of fires on bridges, the temperature acting on the load-bearing structure is, on the whole, somewhat lower than in the case of fires beneath bridges. It was proposed that temperature-time curves based or factorised on the basis of the ZTV-ING curve should be used as a benchmark fire scenario. 


Generalised, directly applicable benchmarking aids were developed and were used to assess the load-bearing capability of different bridges. The application of these benchmarking aids was demonstrated on various types of bridge structure.

Development of a driver’s cab made from aluminium foam composite for high-speed trains 


The development and application of innovative lightweight construction materials and concepts is becoming increasingly important in many sectors of industry for commercial, environmental and functional reasons. 


The goal of the project was to build a bridge between existing concepts and bring together the advantages of existing material solutions. One solution that looked promising was the recently developed material group of aluminium foam composites, in particular aluminium/aluminium foam sandwiches (AFS). These composites unite the advantageous properties of both material concepts and allow for a purely metallic construction that has many benefits in terms of its production and use. 


The overall goal of the project was to develop a lightweight, self-supporting driver’s cab in a hybrid metal construction which met all the requirements in terms of crash behaviour, durability and fire protection for rail vehicles. Here, a particular focus point is developing a production technology for manufacturing a lightweight front module of this kind that is suitable for series production and also energy- and resource-efficient.

Investigations into the self-sealing of penetrating cracks in reinforced concrete constructions used in agriculture 


The research project involved experimental investigation into the self-healing behaviour of penetrating cracks in reinforced concrete constructions under the influence of liquid manure, slurry and silage effluent (MSE) in structures used for agricultural purposes. The experimental investigations were designed to test the self-healing behaviour of the reference fluids used at the time to model MSE fluids against the self-healing behaviour of real slurry. In addition, liquids with varying suspended particle content were tested and evaluated in order to experimentally validate the use of the MSE reference fluids in respect of self-sealing properties. A further key element of the project was the provision of reliable test results in order to assess the quantities of escaping fluid to be expected and the maximum fracture width.

Realistic numerical calculation methods for predicting the behaviour of structures and fluids 


The project involved creating, verifying and validating constitutive models to produce numerical calculations that are as realistic as possible for predicting the behaviour of structures (component behaviour) and fluids (propagation of smoke, propagation of temperature). 


These engineering programs cannot be used to forecast real component behaviour – as opposed to standardised behaviour –, and in particular, they cannot be used to forecast the failure of load-bearing structures. Instead, this real load-bearing behaviour is determined by means of experimental testing, which forms part of the service portfolio provided by MFPA Leipzig GmbH. If the numerical simulation is intended to provide scientific support for this testing, it is the real and not the standardised structural behaviour that must be modelled. 


One subgoal of the project was therefore that the material models (which are published in relevant journals and are absolutely essential for the numerical calculations) should be implemented into the in-house FEM program used at MFPA Leipzig GmbH. This program has no encrypted program sections and thereby offers the full range of monitoring and control options for numerical simulations, making it suitable for long-term development. A further subgoal was the preparation of special solutions on the basis of CFD programs (CFD = computational fluid dynamics) for calculations in fluid mechanics issues, in particular in the field of fire protection.

Development of mineral-based materials for storing heat during the daytime as a buffer for use with sol


The goal of the “Energy Revolution”, the transition from nuclear and fossil fuels to sustainable energy sources, is to be achieved by improving the energy efficiency in homes and in industry, and by increasing the use of renewable energy sources.  


The goal of the research project, run jointly by MFPA Leipzig GmbH and the Institute for Mineralogy, Crystallography and Materials Science at Leipzig University, was to develop a mineral-based material which can withstand the very high temperatures that occur periodically during charging and discharging and the – local – very rapid changes in temperature, without damage, sustainably and for the long term, while also demonstrating good properties as an accumulator.


The research project was part-funded by the Nagelschneider Foundation.
