Experimental characterization to determine the influence of different binder systems on the preform permeability during RTM manufacturing

Experimental characterization to determine the influence of different binder systems on the preform permeability during RTM manufacturing

For fixation of the preforms during RTM-manufacturing, mainly adhesive binders are used, where a uniform layer of these binders are applied between the textile layers. Previous investigations [1 – 3] showed that the laminar application of binder leads to a reduction of preform permeability for the injection process. In the following study a new preform fixation approach, called “Chemical Stitching”, is introduced and its influence to permeability is examined. For the permeability measurements, a 1-D test setup is used, which is mainly geared to unidirectional fiber textiles. To do the measurements under suitable conditions, specialized sensors are used to detect the flow front and the pressure history in the cavity.
