The interior of our largest industrial furnace: This is where large demonstrators such as pressure bulkheads (4.5 m diameter) and booster housings (6 m long) can be produced.
In the small furnace, preliminary tests and feasibility studies are typically carried out on a scaled basis (here: vacuum consolidation of angular elements)
The Institute of Structures and Design (BT) at its sites in Stuttgart and Augsburg operates four furnaces for the investigation of fibre-reinforced structural component production processes.
The technical specifications of the furnaces in detail are:
Furnace Facilities in Augsburg
Furnace 1:
interior dimensions: 5 m x 4.5 m x 8.5 m
max. temperature: 230°C
temperature uniformity: ±5°C
Furnace 2:
interior dimensions: 3 m x 3 m x 5 m
max. temperature: 410°C
temperature uniformity: ±5°C
Furnace 3:
interior dimensions: 1.5 m x 1 m x 1 m
max. temperature: 450°C
furnace class 1 with type A instrumentation
AMS 2750E
Furnace Facility in Stuttgart
Furnace 4:
interior dimensions: 2 m x 1.2 m x 1.2 m
max. temperature: 450°C
temperature uniformity: ±5°C
The scope of performance of the furnaces thus ranges from small laboratory furnaces for preliminary tests to large facilities for the production of full-scale demonstrators. For example, pressure bulkheads (4.5 m diameter) and boosters (up to 6 m in length) have already been manufactured with partners from the aerospace industry.
Research focuses on the investigation of production processes for the infusion of dry fibre preforms by means of vacuum infiltration with thermosetting resins (using the VAP and VARI processes), as well as the vacuum consolidation of high-performance thermoplastics.
