Summary

Resin Injection Molding techniques like RTM offer high potentials to manufacture advanced continuous fiber-reinforced plastics (FRP) combining a wide range of resin systems and reinforcing materials. The application of a pre-stitched reinforcing package, Non Crimp Fabric (NCF), provides minimum effort in lay-up and quality control as well as outstanding mechanical performance.

Main factors influencing the injection process are the viscosity of the resin system and the permeability of the reinforcement. Characterizing the drapeability of fiber structures offers valuable information on the general design of the preform structure as well as the influence on permeability alterations. With respect to design and manufacturing limitations the drapeability of non crimp fabrics is investigated by a 3-dimensional test.

Materials tested have two different lay-up sequences. While one construction represents a typical bidiagonal style with e-glass in ±45°-direction, the second is a triaxial NCF with a stacking in 0°/±45°-direction. Different binder types and stitching lengths are investigated as well. Results show a main influence of area weight, stitching and lay-up configuration.
