Powder binding
The powdering of fabrics refers to a process in which polymers in powder form are applied to the textile structure. This is an important processing step in automated fiber composite technology, especially in the production of preforms or semi-finished products.
Typical areas of application
The advantages of Powder Binding at a glance
Fixation of the fiber layers
The fabrics no longer slip and the draping process becomes easier.
Even resin distribution
The powder can already provide parts of the matrix, which improves resin flow paths.
Process simplification
Preforming is faster, and less additional adhesive or spray is required. It also allows the decoupling of the shaping and impregnating processes.
Cleanliness
Customizable properties
1
A powder is sprinkled evenly onto the surface of the fabric and fixed in place.
2
The powder is then thermally activated at the start of component production so that it fixes the fibers or serves as a matrix precursor.
