Fiber reinforced polymers receive a lot of attention from industry and research due to their outstanding properties that have the possibility of creating revolutionary lightweight technologies. This affects transportation vehicles, such as cars, trucks, trains and airplanes and other products of daily life. This is why it is the main objective of the International Research Training Group (IRTG) – registered under GRK2078 – to train postgraduate engineers for the development of innovative lightweight technologies and to develop robust integrated engineering strategies.
CoDiCoFRP stands for Continuous-discontinuous long fiber-reinforced polymer structures. These structures combine the design freedom of discontinuous- and the high stiffness and strength of continuous fiber-reinforced polymers. However, there is still a lack of proven concepts for the manufacturing, modeling and dimensioning of CoDiCoFRP. The main advantage of DiCoFRP is their bulk material flow capability, which - compared to CoFRP - increases the design freedom for components significantly. The benefit of CoFRP is the high load-bearing capacity, which is much higher compared to DiCoFRP. From an engineering point of view, an optimal combination of design options on the one hand and high stiffness and strength on the other hand can be obtained by combining DiCoFRP with local continuous fiber reinforcements (CoDiCoFRP).
