Abstract: | Compared to metal materials, textile reinforced composites show interesting features, but also higher production costs because
of low automation rate in the manufacturing chain at this time. Their applicability is also limited due to quality problems,
which restrict the production of complex shaped dry textile preforms. New technologies, design concepts, and cost-effective
manufacturing methods are needed in order to establish further fields of application. This paper deals with possible ways
to improve the textile deformation process by locally applying a fixative to the structure parallel to the cut. This hinders
unwanted deformation in the textile stock during the subsequent stacking and formation steps. It is found that suitable thermoplastic
binders, applied in the appropriate manner do not restrict formation of the textile and have no negative influence on the
mechanical properties of the composite. |
