Institute for plastics technology
The Institute for Plastics Technology ( ICT ) at the University of Stuttgart is a research and teaching institute in Stuttgart-Vaihingen . It is part of Faculty 4, Energy , Process and Biotechnology .
history
At the beginning of the 1960s it became clear to the then Technical University of Stuttgart, on the one hand, that plastics were becoming an increasingly important class of materials and, on the other hand, that they behave so completely differently from classic construction materials .
Initially, in 1963, a professorship for materials science of metals and plastics was to be established in the materials testing institute (MPA), but the designated head, Wintergerst, negotiated that the chair should be renamed independently and shortly afterwards to "Institute for plastics science and plastics testing (IKP)" . After starting out on Cannstatter-Strasse, the institute then moved to Pfaffenwaldring 32.
Just one year later, at the instigation of Otto Fahr , the then board member of Werner & Pfleiderer , now Coperion, another institute, the Institute for Plastics Technology (ICT), was founded. Under the direction of Schenkel, this dealt with the processes and machines for plastics processing and plastics processing. Initially housed in rooms on Keplerstrasse, it found its place in the old Benger building at Böblinger Strasse 70.
The then institute directors Wintergerst (IKP) and Schenkel (IKT) as well as their successors Peter Eyerer and Hans-Gerhard Fritz , co-founders of the Polymer Processing Society and its president from 1989 to 1991, later together with Gerhard Busse and Manfred Wagner , gained international scientific attention Findings gained and always actively transferred to industry. In the 1990s, the two institutes together had around 100 scientific and around 40 technical employees, most of whom were self-financed.
At the beginning of the 1960s, the two institutes IKP and IKT were founded with complementary orientations at different locations. In 2010 the University of Stuttgart placed them in the hands of Christian Bonten , with the clear task of building on the successes of the past decades. As early as 2014, the university management strengthens the institute with another W3 professorship for Marc Kreutzbruck . The new Institute for Plastics Technology will merge into the previous rooms of the IKP on the university campus in Pfaffenwaldring over the next few years in order to be close to the Stuttgart students.
Research priorities of the ICT
Research in plastics technology has three facets: material technology, processing technology and construction technology / product development. Research - very similar to development - deals with increasing the efficiency of plastic as a material in materials technology, with increasing the efficiency of processing machines, tools and processes in processing technology and with increasing the efficiency of plastic products in product development. While special solutions for an application are sought during development, research always tries to develop general solutions. Examples of current research activities can be obtained by moving the mouse over the respective fields of competence.
Materials engineering
In order to make a material “more effective”, that is, to make its property profile wider or deeper, the current condition of the material must be suitably determined with the help of material testing methods. In plastics technology, a plastic is created through a processing process only through a novel combination of polymers with additives. Significant improvements were achieved at the IKT, particularly in the area of new bio-based and biodegradable plastics. In addition, the constant goal of materials technology is also the predictability of the material behavior in use. For this purpose, research is carried out on complex material models B. map the time and temperature behavior realistically.
- Research on testing and measuring methods for plastics
- Research on plastic-specific material models to predict material behavior
- Increase the efficiency of the material through processing
Processing technology
In order to make a machine, the tool or the manufacturing process more efficient, their condition must first be sufficiently described. It may be necessary to first invent suitable measuring equipment and methods for this. In order to be able to predict the behavior of the machine and tool in the process, research is carried out on model-like and as universally applicable mathematical descriptions of the respective process as possible in order to be able to simulate it realistically. In the area of single-screw extrusion in particular, the IKT gained importance through the development of a continuously grooved extruder with a barrier screw.
- Research on rheometry and interpretation of the measurement results
- Realistic rheological-thermodynamic modeling of plastics processing processes to predict process behavior
- Increased efficiency in plastics processing: extrusion , injection molding , thermoforming
Product development
A plastic product can be made more effective, e.g. B. in which it fulfills several functions at the same time or the previous function with more demanding boundary conditions. To do this, the product condition must first be determined and, if necessary, research into measuring equipment and methods. With the help of material laws, research is carried out on the predictability of product behavior, especially the service life prediction under different operating conditions. With the help of calculations, the component behavior is simulated and validated with selected tests. The ICT achieved special international importance as new NDT processes for modern materials were developed under the direction of Gerhard Busse and used to address industrial issues, e.g. B. were tested in the aviation industry. In this context, for. B. 1995 the defect-selective ultrasonic lock-in thermography and the overtone scanning vibrometry were developed and microwave methods were used to measure fiber orientation fields in injection-molded components.
- Research on non-destructive testing (NDT) of components made of plastics and fiber-reinforced plastics using the methods of active thermography , interferometry and ultrasound
- More precise prediction of component behavior using plastic-compatible material models
- Research into permissible accelerated aging
- Research on better models to predict lifespan
- Higher product efficiency through functional integration and the choice of more efficient materials
All three areas are interlinked and are interdependent, because with plastic products a construction not only has to be suitable for the stress, but also suitable for processing and material.
