Junior research group

Young scientists from the Fraunhofer WKI and the TU Braunschweig are working together to develop solutions for sustainable buildings.


Junior research group

The multidisciplinary junior research group is currently investigating the long-term behavior and durability of wood-hybrid systems for load-bearing structures in building construction. 


Long-term behavior of wood hybrid systems for sustainable buildings

In the establishment of sustainable construction methods for the future, wood plays an important role as a building material made from renewable raw materials. The native properties of wood can at present restrict the utilization of this sustainable material in construction projects. In order to compensate these typical wood properties, innovative hybrid systems can be advantageously applied.

Current research projects


Lightweight sandwich element with recycled balsa wood

Using a stand-up paddleboard as an example, we are developing a lightweight-construction sandwich element using renewable raw materials. For the core, we are using balsa wood from disused wind-energy rotor blades, thereby offering a solution for their high-quality reutilization (cascade utilization). The outer shell will be made of natural fiber-reinforced bioplastics.


Ecological insulating materials and components for Chile

In this project, we will develop insulating materials from Chilean plants and largely unused plant “waste“ that accumulates in Chilean agriculture, forestry and timber industry. In this way, we contribute to sustainable forest management and to improving the environmental balance of the construction industry in Chile and open up new value creation opportunities.


Bio lightweight building board for the interior construction of ships

Due to the fire-protection requirements, solely non-regenerative materials such as aluminum or foam glass have been used up until now for interior fittings in ships. In this project, we are developing a non-combustible lightweight board made from plywood which is suitable for cabin construction in ships and which is, furthermore, much easier to work with.


Glimmer-protected wood-fiber insulation

Wood fibre insulating materials are good for the environment, but currently only reach building material class B1 (normally flammable). In building classes 4 and 5, they may therefore only be used with an approval in individual cases. We are developing a climate protection system for sustainable wood fibre insulating materials to improve their building material class and expand their market potential.


Fire-safety in public facilities

What fire-safety requirements exist for products such as textiles, furniture and mattresses in public facilities? How can the requirements be fulfilled in the most environmentally friendly and health-compatible way possible? In this research project, we are developing a concise guideline with defined recommendations for purchasers.


Composite thermal insulation systems with bio materials

Renewable raw materials exhibit a high absorption of moisture, which can be beneficial for their application as an insulation material, particularly in the case of prolonged unfavorable moisture conditions. Within the framework of the collaborative project “More than just insulation - Additional benefits of insulation materials made from renewable raw resources” we are investigating composite thermal systems with insulation materials made from renewable raw materials.
