The BioMat research group (Bio-based Materials and Materials Cycles in Architecture) at ITKE (Institute of Building Structures and Structural Design) presents the research project PLUS (Sandwich Panels out of plant residues with integrated Acoustic Absorption and Thermal Insulation Properties)
The project is funded by FNR (BMEL), Germany from (01.01.2015-31.12.2017), FKZ: 22008413, lead by Jun.-Prof. Dr.-Ing. Hanaa Dahy, BioMat Director at ITKE, Faculty of Architecture and Urban Planning at the University of Stuttgart

The project aims to find further sustainable solutions for contemporary architecture, through the development of new ecological building materials that are based on biocomposites (natural fibre reinforced bioplastics) based on annualy renewable agro-fibres and bioplastics.
The developed bio-sandwich panels have integrated acoustic absorption and thermal insulation functions.

PLUS Project Intro:
The intelligent processing of plant fibres to building materials can lead to more sustainability in the construction industry. The development of a light construction panels, purely based on annual renewable materials provides a whole range of ecological and economic benefits for indoor architectural applications. This shows an alternative to the rapidly increasing consumption of non-renewable and slow-renewable resources.
The aim of the project is the development, characterization and initial application of two biocomposite extruded plates consisting of up to 100 percent of plant-based renewable raw materials. The plates can be combined to be applied as sandwich panels based on natural fibre composed biosomposites and biofoams with integrated acoustic absorption and thermal insulation functions. Each developed extruded plate can be applied thermoformed for free-form applications, depending on the thermoplastic basis of the developed plates.

The project has a duration of 36 months and is organized in a cooperation partnership between research and development organizations and small and medium-sized enterprises.
The project phases are divided into different work packages, including design, material development, fabrication, and building of individual prototypes of the developed materials. The fabricated prototypes were exhibited in different exhibitions including JEC Composites Exhibition in the sustainability planet show in Paris in 2015, in the Hannover Industrial Exhibition in Germany in 2016 and 2017, in the Materials Revolution in Sweden in 2016 and in Orgatec in Cologne in 2016.
After the completion of the project, the marketing phase of the newly developed materials and products will take place. The application of these novel ecologic materials on a wider scale in architecture and building industry will lead to a direct social, economic and ecologic positive feedback to the built environment and to society.

BioMat is a newly established research group in ITKE since 2016. The main concept of this group is establishing new emerging concepts in the field of sustainable architecture. Materiality, energy efficiency, multi-functionality and life cycle scenarios are integrated. The match between architectural design, lightness, functional gradation, interactivity, material development and fabrication are seen as emerging perspectives that affects sustainability in future architecture.
Architects and engineers are working hand-in-hand in collaboration with different disciplines including mechanical-, material-, electrical-, IT-, textile- engineers, biologists as well as industrial bodies to achieve these scopes together. These disciplines are highly integrated in current funded industrial-research as well as research-teaching projects.
Research fields: biomimetics, sustainability, new building materials-development and fabrication, fibre reinforced composites, product design, multi-functional building systems
