New and Challenging Material Class

Discontinuous long fiber reinforced polymer structures with local continuous fiber reinforcements represent an important and new class of lightweight materials. This class of materials has a significant potential for energy savings due to the high specific stiffness and strength as well as the variety of design options in diverse technical applications, e.g., in vehicle construction.

State of the Art

In contrast to the continuous fiber-reinforced composites of non-crimp or woven fabrics, which are used, for example, in the aircraft industry, there is still a lack of integrated and experimentally proven concepts for the manufacturing, modeling and dimensioning of combinations of discontinuously and continuously reinforced polymer structures. Reasons can be identified, on the one hand, in the complexity of the processes in manufacturing discontinuously reinforced polymers themselves and consequently in the resulting heterogeneous, anisotropic and nonlinear material and structural properties, and on the other hand, in the resulting bonding problem of both material types induced by the manufacturing process.

Challenge

Especially in the field of application of three-dimensional load-bearing structures, there is considerable demand for both the enhancement of scientific methods as well as the education of engineers, who have an interdisciplinary understanding of the corresponding process and material techniques along with the necessary simulation and product development methods.

Interdisciplinar Research

In recent years, there has been considerable progress with respect to characterization and numerical methods. Nowadays, it is possible to combine the methodological progress in material science, computational mechanics, production techniques and design methods in an integrated approach.

Objective

The main objective of the IRTG is, therefore, to enable the efficiently structured education of doctoral candidates in this strategically important but not yet developed field of continuous-discontinuous long fiber-reinforced polymer structures, by taking advantage of the complementary competencies of the applicants from Germany and Canada.

German Canadian Cooperation

The complementary research emphases of the participating institutions are respectively strongly ‎cross-linked to the local national industries and research structures, ensure a versatile education and, in the medium term, a transfer of research results to industrial applications.
