Full textTailored Fibre Placement (TFP) allows manufacturing flat, net shape fibrous reinforcements with continuously varying orientation and thickness. The hybridisation of TFP and forming is an attractive solution to manufacture mechanically optimized 3D shelllike composite parts. During the forming of complex parts, inevitable fibre path changes occur in the TFP preform. Prediction of the final state of TFP preforms is required to take full advantage of this hybrid solution in the industry.A first numerical modelling strategy is proposed to address the forming of flat TFP preforms. Two semi-discrete models based on an embedded formulation are developed to offer the possibility of removing or keeping the backing material. Both finite element models use an explicit discretisation of the fibre tows using beam elements and assumes no slippage between the preform constituents. Full-scale validations of the model without backing material are successfully addressed by forming hemispherical and tetrahedral parts with final orthotropic orientations. Finally, a mixed embedded element-ALE (Arbitrary Lagrangian Eulerian) formulation is proposed to introduce fibre slippage into the models without modifying their initial ingredients. A parametric study of pull-out experiments is performed to characterize the friction behaviour to be implemented in the models. Numerical validations for TFP preforms and an extension to model fibre slippage in conventional textiles are proposed

Full textThe present work demonstrates the stiffness and strength design of fiber reinforced plastics (FRP) made by the Tailored Fiber Placement (TFP) technology using the example of a a turbo molecular pump (TMP) rotor made of carbon fiber reinforced epoxy resin (CFRP). In contrast to other textile preform manufacturing processes, the TFP technology enables the placement of reinforcement rovings in arbitrary direction according to an user defined design path. In this technology a double locked stitch in a zigzag stitch pattern is used to fixate the rovings. The fixation process leads to waviness and material inhomogeneities within the placed rovings resulting in reduced material properties in TFP-based fiber reinforced plastics. The wavinessinducing effects have been identified and quantified by detailed process analysis and morphological investigations. Subsequently, a meso-scaled representative volume element (RVE) of a TFP unit cell based on finite elements was developed. The RVE provides the opportunity to derive realistic material properties by calculating the stress and strain distribution as well as as the local fiber content in TFP-based FRP. In this work, the influence of different TFP process parameters on the resulting modulus and strength has been investigated using the RVE approach. Additionally, long term loading effects leading to a reduced matrix modulus were analyzed numerically with the RVE. Based on the development of the CFRP TMP rotor specific characteristics of the design process for components made of TFP are clarified. Besides the explanation of loading conditions of TMP rotors the progress of a load-adapted fiber layout considering geometrical restrictions is demonstrated. For the stress analysis based on the Finite Element Method (FEM) material data calculated with the RVE according to the applied TFP process parameters have been integrated into the FE model. The numerically determined failure speed and the calculated eigenfrequencies were successfully validated by experimental tests. By implementing TFP specific material data in the FE model, both, the strucural rigidity as well as the strength, were predicted for the first time in a TFP-based component. Compared to the state-of-the-art, the developed TMP rotor offers an increased failure speed by 45 %. Furthermore necessary geometric modifications for FRP based TMP rotors in order to achieve a material-specific design adapted to the orthotropic material properties and thus to further increase the nominal rotational speeds were shown. These findings provide in a generalized way for a material-specific design of TFP-based FRP components
