FE results for the picture-frame test
Figure 7 shows the FE results of the discrete approaches for dry
fabric. All the models are in good agreement with the experimental results. At a displacement of 80 mm of the pictureframe, meaning a shear angle of about 40°, the simulations result
in higher forces. Thus, the models have a higher shear stiffness
for higher shear angle values compared to the test specimens.
Simulations with truss elements in combination with shells or
membranes and P2P mesh result in the same force values. The
Beam_Shell model with the checkerboard mesh shows lower
tensile forces of the picture-frame compared to the Pin-to-Pin
mesh. However, the difference is not significant in this case. In
future work, the models have to be compared within a forming

study when significant inter-tow sliding can occur.
The Truss_Membrane_P2P_PA6 model with an elasto-plastic
constitutive law for the matrix component shows the increasing
tensile force at the beginning of the picture-frame test, but stiffness is also too high, especially for higher shear angle values.
There is a good agreement of the FE results of the *Fabric
material model with the experimental test results of the dry and
impregnated fabric with PA6 (Figure 8), even for high shear
angles.
Furthermore, there is less pre-processing effort because no 1D
elements are required. This reduces simulation time. There is no
need to validate the material input data, contrary to the discrete
approaches.

Double-dome sensitivity study
The simulation of the double-dome part is performed for the
*Fabric material model due to its good agreement with the experimental results of the picture-frame test and little time effort,
even for the pre-processing and validation steps.
The FE model consists of a die, a punch, a binder and a sheet.
The latter is just a quarter of the size of the part due to the sym-
