The Fraunhofer Centre for High Temperature Lightweight Construction HTL offers contract research in the application areas of aerospace, energy technology and thermoprocess technology as well as in the product area of technical ceramics. For our customers, we develop and optimise technologies, processes and products up to the production of prototypes and small series. Find out more about our current publicly funded research projects here.
Duration 2021 - 2024
Novel composite materials for high-temperature heaters and gas-electricity hybrid furnaces
Within the scope of the project, novel MMC resistance heaters will be developed.
Development of a fibre-reinforced near-net-shape airfoil made of highly rigid oxide ceramics
Within the scope of the project, a technology is to be developed with which a near-net-shape 3D preform of engine blades for aircraft gas turbines (airfoils) can be integrally woven from oxide ceramic fibres and suitable for series production.
Digitisation of material development along the value chains
In DiMaWert, a methodology is to be established which will radically reduce the development times for new types of thermal processes. In addition to thermal processes, DiMaWert also aims at material and component development, which is also to be accelerated considerably with ICME and AI methods.
Duration 2020 - 2023 Development of SiC-fabrics for the winding process for the production of high temperature resistant tubes
In RoSiC, textile fabric structures for tubular SiC/SiC composites will be developed. On the other hand, multilayer fabrics are to be developed which can be easily processed and infiltrated in the winding process to tubular components.
Duration 2020 - 2023 Energy-efficient high-temperature processes for large and geometrically complex components
In HTPgeox, a methodology will be developed and tested using the example of sanitary ceramics, with which the production of components can be optimised in terms of energy efficiency and product quality through the interaction of digital processes.
Duration 2020 - 2023 Development of a basalt fibre reinforced mixed oxide ceramic using the example of a hand pouring crucible
The aim of BaMOX is to develop a ceramic fibre composite material (CMC) which meets the requirements of the casting process and is more cost-effective to produce than the alternative materials used so far.
Duration 2020 - 2022 Round needled C/SiC tubular structures for space travel
In RuRoRa, tubular structures with an increased fibre content in the Z-direction are to be produced by round needling of semi-finished textile products. Thereby improved properties in form of an increased interlaminar shear strength shall be achieved.
Duration 2020 - 2022 Spherical pressure vessels for hydrogen storage
In KuWaTa a spherical isotensoid high pressure tank for the storage of hydrogen at 350/700 bar is to be developed. The tank will be made of carbon fibre reinforced plastics ( CFC ) and by automated forming processes such as winding or tape deposition.
Duration 2019 - 2022 Dense oxide ceramic CMC components for micro gas turbine applications
In DoMiGat an O-CMC is to be developed which can be used at significantly higher temperatures up to approx. 1250 °C. A stator for micro gas turbines as a demonstrator component is to be developed from this novel material.
Duration 2019 - 2022
Development of a coating of short fibres using the fluidised bed coating process
The overall objective of 3D-FRG is the additive production of fibre-reinforced SiC/SiC and C/SiC components with significant property and environmental advantages over conventionally processed ceramics.
