Abstract
Novel textile reinforced composites provide
an extremely high adaptability and allow for the development
of materials whose features can be adjusted precisely
to certain applications. A successful structural and
material design process requires an integrated simulation
of the material behavior, the estimation of the effective
properties which need to be assigned to the macroscopic
model and the resulting features of the component.
In this context two efficient modelling strategies - the Binary
Model (Carter, Cox, and Fleck (1994)) and the Extended
Finite Element Method (X-FEM) (Moës, Cloirec,
Cartraud, and Remacle (2003)) - are used to model materials
which exhibit a complex structure on the mesoscale.
For these investigations the focus is set on composites
made of glass fibers, thermoset or thermoplastic
matrices and on the application of commingled thermoplastic
and glass fibers. Homogenization techniques are
applied to compute effective macroscopic stiffness parameters.
Problems arising from a complex textile reinforcement
architecture, e.g. bi- or multi-axial weft-knit,
woven and braided fabrics, in combination with a high
fiber volume fraction will be addressed and appropriate
solutions are proposed. The obtained results are verified
by experimental test data.
The macroscopic stress and strain fields in a component
are used for optimization of the construction and
the material layout. These distributions are computed
in a global structural finite element analysis. Based on
the global fiber orientation the required macroscopic material
properties obtained from homogenization on the
meso-scale are mapped to the model of the structural
part. The configuration of the fiber-orientation and textile
shear deformation in complex structural components
caused by the manufacturing process is determined by a
three-dimensional optical measurement system.
