Material Design

The specific material application of the customer results in a list of thermal, mechanical, electrical, and chemical properties that have to be considered and implemented to achieve a proper material design. The material processing may be accompanied by constraining factors which will be covered by computer simulation analysis.

Which material will yield the optimum technical and economical solution? Could it be necessary to use composite materials? Fraunhofer-Center HTL approaches questions like these, backed by its profound knowledge and expertise in the field of Material Design (see Raether, F.: Ceramic Matrix Composites – an Alternative for Challenging Construction Tasks).

The requirement profile is systematically analyzed in order to identify the key decision criteria. Current available solutions are reviewed for weaknesses and strengths. The aspects of ceramic compatible designs are incorporated into the computer simulations and modellings. With the help of material databases, in-house studies and computer simulations, we at Fraunhofer-Center HTL determine the optimal material design with respect to the intended usage.

At Fraunhofer-Center HTL we calculate the material properties of multiphase materials based on the microstructure. On that account Fraunhofer-Center HTL has specially developed in-house software and commercially available finite element programs at its disposal. In order to have sufficiently precise simulation results, they are experimentally calibrated and validated. All necessary testing methods for the quantitative microstructural analysis and for measuring thermal, mechanical and electrical material properties are available. The structures are computer-optimized for the specific tasks of the customer. Pores and melt phases are adequately considered. If required, Fraunhofer-Center HTL can develop the appropriate manufacturing processes for setting the optimal microstructure and material properties. The process development is carried out efficiently with the help of in-situ measurement methods and computer simulation.

At Fraunhofer-Center HTL, we use computer simulations in order to achieve precise material designs. In addition to commercial methods, there are also in-house models at our disposal.
